Sunglasses are definitely a fashion favorite and a great tool for styling in the shinny summer. But how do we choose the right sunglasses? Do we really need them? How important is the color of the lenses? What about the size of the lenses and eyewear frame? There’s actually a lot to learn about this.

Choosing Lenses
How to pick good lenses? Sunglasses are categorized into light-absorbing, polarized, coated, and photochromic types. The best lenses are polished using optical procedures, just like the optical frame prescribed by doctors. Plastic lenses, similar to Rx ones, vary greatly in quality. Generally, plastic lenses are lighter, shatterproof, and cheaper; however, they are prone to scratches, so special care must be taken when touching or cleaning them.

There are several simple ways to test the lenses: Observe them under light. The lenses should be completely clear, with no cross scratches, streaks, circles, bubbles, or stains at all. Move the lenses up, down, left, and right to look at objects with distinct lines, such as window frames or door frames. If these objects appear wobbly or distorted, the lenses have distortions and are not usable. To check if the lens color is uniform, pay attention to whether the two lenses have the same color and if their gradually lightening parts are in the same positions.

Lens Colors
The price of sunglasses doesn’t entirely reflect their optical quality. Because the most expensive ones may just have novel designs, and what you’re paying for could be the fashionable eyewear frame rather than the optical quality of the lenses.

What color is the best? Generally, natural pure gray and “smoke” colors are the best. Lenses of these colors are the hardest to manufacture, so inferior sunglasses won’t use them. Next is green. Blue and red lenses are only used in certain industrial applications. There are also special yellow lenses. Therefore, the choice of lens color depends on the purpose. How dark should the color be? The darkest colors are suitable for use in strong light. It’s very dangerous to use them when driving on roads with fluctuating light conditions. Many people find the lenses of the sunglasses they buy suitable in brightly lit stores, but they turn out to be too light when used at the beach or in the countryside. The best way is to take the sunglasses outside and look at the sun. It’s advisable that only 20% to 30% of the light can pass through in strong sunlight.

There is a rather special eyewear product called a “sunglass clip-on”. It is a type of sunglasses specifically designed for people who wear optical frame. By simply clipping this clip-on onto their existing optical frame, their myopia eyewear can instantly be transformed into sunglasses, thereby providing better protection for their eyes.

How should we choose a sunglass clip-on?
First, check if the sunglasses clip-on has a polarizing effect.

The polarizing effect can help us better distinguish objects under reflected light and strong light, making it suitable for people who fish, ski, or drive. In general, most sunglasses clip-ons have this function. However, regular eyewear brands will come with a polarizing test card, which features patterns of fish and water surfaces for consumers. Therefore, you can try on the sunglasses clip-on, and if you can see the fish, it indicates that its polarizing effect is good.

Second, verify if it has UV protection.

When purchasing a sunglasses clip-on, consumers must confirm whether the product has UV protection. If it only has a light-filtering function but no UV protection, it cannot fully block UV radiation, and the damage to the eyes cannot be avoided.

Third, inspect the structure of the sunglasses clip-on.

Non-regular brands usually use iron components, which can easily cause the lenses to get scratched and even harm the eyes. On the contrary, if we choose big brands, their quality is guaranteed. When the lenses come into contact and bear force, they can avoid the phenomenon of being separated by silicon gel.

In the sweltering summer, a trip to the seaside is definitely the best choice. However, the intense sunlight causes trouble for those of us who are nearsighted. At this time, we need a pair of sunglasses, so how should myopic people choose the right sunglasses?

Myopic sunglasses lenses are mainly divided into three types: photochromic myopic sunlenses, tinted myopic sunlenses, and polarized myopic sunlenses. These three types of sunlenses have a common advantage: they are all suitable for all optical frame and sunglasses frame with small curvature, and combine sunglasses and optical frame in one, which is more aesthetically pleasing.

Main features of photochromic myopic sunlenses: Photochromic sunglasses adjust the depth of color according to the intensity of ultraviolet rays, which can meet the needs of wearing indoors and outdoors and effectively prevent ultraviolet rays. However, when used in a car, the ultraviolet index inside the car is usually unstable, so the photochromic effect is not very ideal.

Main features of tinted myopic sunlenses: Tinted resin sunlenses are relatively low in price and economical. However, ordinary tinted myopic resin sunlenses may not have a good ultraviolet protection effect if there is no additional coating.

Main features of polarized myopic sunlenses: The advantage of polarized myopic sunlenses is that they can effectively prevent ultraviolet rays, but their price is relatively high, and they are not suitable for indoor wear. Moreover, the polarized myopic lenses sold on the market currently only have a refractive index of 1.50. For people with high myopia, the sunlenses will be relatively thick.

Factors to consider when purchasing:
Appearance inspection: In addition to ensuring that the sunlenses have no scratches, impurities, bubbles, or streaks, ladies who love beauty must pay attention to the fact that only those with UVA, UVB protection and CE marks on the sunlens surface or tag can play the role of ultraviolet protection.

Myopic sunlens quality: Hold the lens about one foot in front of your eyes, look at a fixed object through the center, and then move it up and down gently. If it is a plain lens, the object should not move. If the object moves with the lens or is distorted, it means the lens is not flat and has unevenness. Such sunglasses should not be bought.

Depth of color: Sunglasses with too light colors have little light-filtering effect; while too dark colors can easily affect vision. In general, brown, gray, and dark green are more appropriate. They have good light-filtering effects, and the scenes seen after wearing the glasses will only become darker without obvious color difference.

Ultraviolet protection function: We cannot distinguish with the naked eye whether a pair of sunglasses has the function of ultraviolet protection. The manufacturer’s explicit commitment to the product is the only reference for consumers to choose sunglasses with protective functions. We can see explicit labels such as “100% UV protection”, “UV400”, “blocks all ultraviolet rays”, “UV protection” on the labels of some products and the front of the eyewear.

Comfort is the key: When choosing a pair of sunglasses, don’t blindly follow the trend. You should also choose the size and curvature of the eyewear according to your face shape. In addition, when trying them on, check if there is a sense of dizziness to avoid accidents such as car accidents caused by dizziness from wearing inferior sunglasses. Also, check if the transparency is high, and it’s better to have a polarized function.

Sunglasses, also known as sunshades, as the name suggests, are used to block the sun. They prevent direct sunlight from causing significant damage to eyesight. But today, we’re going to introduce a special type of sunglasses: polarized sunglasses.

Polarized sunglasses are a category of sunglasses, but they are among the more high-end ones. They have a function that ordinary sunglasses don’t: they can effectively block and filter out various harmful polarized lights.

The so-called polarized light refers to the irregular reflected light generated when light passes through uneven road surfaces, water surfaces, etc., also known as glare. When these lights directly shine into people’s eyes, they can cause discomfort, easily lead to fatigue, make it impossible to see things for a long time, and significantly reduce the clarity of the viewed objects.

Ordinary sunglasses only work by dimming light. Since ordinary lenses cannot filter light, they can only reduce the intensity of glare, ultraviolet rays, etc., but cannot completely block these harmful rays. So their function is only to reduce damage to the eyes, but the biggest advantage of ordinary sunglasses is their good fashionability. Polarized sunglasses lenses, due to their polarizing properties, can completely block the dazzling glare caused by scattering, refraction, reflection and other factors. At the same time, they can also completely block ultraviolet rays that are harmful to human eyes, so that when people are active in strong light for a long time, their eyes are not easily fatigued, achieving a truly protective effect, and making the things seen clearer and more three-dimensional.

Because polarized sunglasses have the function of polarizing light, they can block all harmful rays without affecting the transmission of visible light, truly protecting the eyes. In addition to the basic ultraviolet protection function, polarized sunglasses also prevent glare, road reflected light, water surface shimmer, etc., making them suitable for driving, fishing, traveling, and daily wear.

Choosing a pair of lightweight and durable sunglasses can definitely protect your eyes in the scorching summer and add a stylish touch to your look. So, what materials should we choose for eyewear lenses? As a professional eyewear supplier, please allow us to briefly introduce several lens materials.

Lens Materials:
Resin: Common types of resin include PC lenses and regular resin lenses.

PC Lenses: PC stands for polycarbonate. Polycarbonate is 57% lighter than glass lenses and 37% lighter than regular resin lenses. It features high toughness, hardness, and shatter resistance, making it ideal for active children and athletes. Additionally, its high refractive index allows PC lenses to be made very thin. What’s more, PC lenses inherently block UV rays—unlike glass, they don’t require a coating to provide 100% UV protection.

However, PC lenses have drawbacks: their strength is lower than glass, so they are not wear-resistant and require a coating for long-term use. They are also softer than glass and prone to deformation under pressure, making them unsuitable for hand-made acetate eyewear or rimless metal eyewear. Their high refractive index also results in a low Abbe number (around 32), leading to significant dispersion.

CR-39 Lenses: Regular resin lenses typically refer to CR-39 resin lenses from the United States. They have a high Abbe number (low dispersion) and a slightly higher density than PC Lenses, but are still much lighter than glass and shatter-resistant. Even if they break, they don’t form sharp edges. Their refractive index is relatively low (around 1.5), so the lenses are thicker.

Glass Lenses: Glass was the earliest material used for eyewear lenses. It is hard, resistant to deformation and discoloration, and less prone to scratching than PC or resin. Its refractive index can be adjusted by adding different substances; ordinary glass lenses have a refractive index of approximately 1.523.

The disadvantages are that glass lenses are heavy—almost twice the weight of resin lenses—and fragile. If they shatter, they can easily scratch the eyes. For these reasons, glass lenses are now rarely used, replaced by resin lenses.

MR Lenses: MR lenses are high-refractive-index materials with the most balanced performance indicators, especially suitable for eyewear production. They are lightweight, provide clear vision, have high pressure resistance, and are less likely to break. Most importantly, they resist yellowing better than ordinary lenses, maintaining clarity and brightness over time, and have excellent corrosion resistance.

Nylon Lenses: Nylon lenses represent relatively new technology. They offer physical strength close to PC and optical performance similar to CR-39, with low weight, making them an ideal lenses material. However, they are more expensive than PC lenses.

Lens Coatings:
All lens materials have drawbacks, so coatings are applied to improve their optical properties.

By Function: Common coatings include hardening coatings, anti-oil coatings, polarizing coatings, anti-UV coatings, and multi-layer coatings combining multiple functions.

By Color: Coatings are mainly green, blue, red-green, etc. The color of the coating has no specific correlation with its function, so there’s no need to focus on it.

Blue is a cool tone, red is warm, and green is neutral. Psychologically, people tend to adapt better to green coatings, making green-coated lenses feel more comfortable (though this is purely a psychological effect).

Hardening Coatings (Scratch Resistant Polymer): These reduce the risk of lens scratches. Glass lenses generally don’t require a hardening coating, but resin lenses must have one.

Anti-Oil Coatings: These not only reduce smudges on the lens surface but also repel water, fog, dust, oil, and other contaminants.

Anti-Reflective (AR) Coatings: Applied to the side of the lens closest to the eye, these prevent ghosting by reducing reflections from light entering the back of the lens. They channel light from the back to the front of the lens, minimizing reflection interference and significantly improving visual clarity, with noticeable benefits for wearers.

While some coatings harden the lens surface, they remain delicate and require careful handling. All coatings have a lifespan; if a coating is damaged, the lens is essentially ruined.

UV Protection:
UV (ultraviolet) protection is a must for sunglasses. It is unrelated to lens color or light transmittance and is typically achieved through coatings. Common labeling methods include:

“UV400”: Indicates the lens blocks UV rays and visible light with wavelengths below 400nm. A lens is considered qualified if it transmits less than 2% of UV rays.

“UV” or UV Block)”: Indicates the lens blocks UV rays with wavelengths below 380nm. A lens is qualified if it transmits less than 2% of UV rays.

“100% UV Absorption”: Claims to absorb 100% of UV rays. In practice, a lens is qualified if it transmits less than 0.5% of UV rays.

SHMC Lenses: means the lenses with Super Hydrophobic coating + AR coating + hard coating anti scratches polymer.

To prevent the eyes from being damaged by the harsh summer sunlight, it is essential to choose a suitable pair of sunglasses. Especially for myopic individuals, wearing low-quality sunglasses not only fails to protect the eyes but may cause greater harm, so caution is advised when purchasing.

For myopic people who want to wear sunglasses, the following methods are available:

Contact lenses + sunglasses: This is not applicable to the main scenario mentioned here, so it will not be elaborated on.

Polarized clip-ons: Convenient but unsightly. They are uncomfortable to wear and prone to loosening.

Dyed myopic sunglasses: Lenses dyed in ordinary stores are prone to color fading and scratching and have a short lifespan. Lenses pre-dyed by professional lenses manufacturers have more stable colors but are relatively expensive.

Magnet-on sunglasses: More stable than clip-ons but heavier. Frequent removal and wearing can easily cause scratches on the sunglasses lenses.

Myopic polarized sunglasses: Highly functional.
Sunlight reflecting off water, snow, or roads creates glare, often causing eye discomfort and fatigue. Polarized sunglasses can effectively filter out these irregular reflected lights, making surrounding scenery appear soft and non-glare. Especially for drivers, anglers, and sports enthusiasts, it is recommended to wear myopic polarized sunglasses. Even for those who do not exercise frequently, purchasing them is cost-effective—they are lighter, more stylish, and have a longer lifespan than other methods.

Shortcoming: If the myopia diopters is high, the lenses will be thicker. Within 800 Diopters, it is still feasible. Of course, MR-8 lenses with a refractive index of 1.6 can be used, which are much thinner but slightly more expensive.

Common sense about optical frame fitting:

Diopters:
The diopter of a lens, commonly known as “degree,” is the most important parameter of a lens.
Thickness is basically proportional to diopter, but there are ways to reduce lens thickness.

Refractive index:
The refractive index is the ratio of the speed of light in a vacuum to its speed in the material.
For the same degree, a higher refractive index means thinner, lighter, and more aesthetically pleasing lenses, but the price is also higher. However, a higher refractive index is not always better, which relates to the lens’ Abbe number.

Abbe number:
Different colors of light have different refractive indices in a medium. When refracted by a lens, the propagation directions of light differ, causing sunlight (composed of polychromatic light) to disperse into different colors—a phenomenon called chromatic aberration. Chromatic aberration affects visual clarity.

The Abbe number measures the degree of chromatic aberration. A higher Abbe number means less chromatic aberration, and vice versa.

Generally, a higher refractive index corresponds to a lower Abbe number and more severe chromatic aberration.

Therefore, when choosing lenses, do not blindly pursue a high refractive index—it not only increases costs but also reduces visual clarity. In general, the refractive index should be selected based on the degree:

Below 200 Diopters: Choose 1.50 refractive index myopic lenses.
200–400 Diopters: Choose 1.50 or 1.56 refractive index myopic lenses.
400–600 Diopters: Choose 1.60 refractive index myopic lenses.
600–800 Diopters: Choose 1.67 refractive index myopic lenses.
Above 800 Diopters: Choose 1.74 refractive index myopic lenses.

After long hours of driving, drivers will feel fatigued, which affects their driving condition. Therefore, wearing Sunglasses while driving is not just about looking cool—they play a crucial role in protecting vision and eyesight, especially in strong light. For driving, Sunglasses are essential auxiliary tools. Today, let’s discuss the Sunglasses suitable for drivers: what types are ideal for driving?

Wearing Sunglasses is not just to block dazzling sunlight, nor is it for vanity; it is directly related to driving safety. When driving, we need to focus on the road ahead. Besides the sun, there are reflections from the road, the rear windshield of the vehicle in front, and glass walls of buildings on both sides. Without the protection of Sunglasses, eye fatigue is prone to occur. Additionally, when the eyes switch between bright and dark environments, the inability to adapt instantly can affect driving safety.
Polarized lens Sunglasses— the best choice for driving
Polarized sunglasses can effectively filter out external stray light and glare. If you plan to buy Sunglasses for driving, remember one term: “polarized sunglasses.” If you don’t want to delve into the details, just remember to choose this type, as they are the most suitable for driving.

Polarized Sunglasses are ideal for drivers because they reduce glare, effectively eliminating and filtering scattered light in beams, making the vision clear and natural. Wearing polarized Sunglasses is like having shutters on a room’s window—the external light is adjusted into parallel light entering the room, making the indoor scenery look soft and non-glare. In addition, polarized Sunglasses can also weaken strong light, reduce fatigue, maintain clear vision, and block ultraviolet rays.
Suitable Sunglasses for driving: Color selection matters
Many people mistakenly believe that the darker the color, the better the UV protection. In fact, the UV filtering function of sunglasses depends on the coating, not the color depth. Especially for long-distance drivers, if the sunglasses are too dark, the eyes are more likely to get tired, and it is more dangerous when entering dimly lit areas like tunnels from strong sunlight.

Sunglasses with excessively dark lenses are not suitable for frequent drivers. This is because overly dark lenses can delay the time it takes for the eyes to send images to the brain, extending the driver’s reaction time to situations and increasing the risk of accidents.
Proper storage of Sunglasses
Avoid placing Sunglasses randomly. It is best to wrap them in an eyewear pouch and store them in the car’s glasses case. Prolonged exposure to high temperatures in the car can easily deform the frames and accelerate color fading of the lenses.

Additionally, since polarized Sunglasses are relatively expensive and difficult to distinguish between genuine and fake products, consumers are advised to purchase polarized Sunglasses from professional eyewear stores. To test the lenses, use a special polarized sunglasses test card—genuine polarized lenses will reveal specific patterns or text on the card, while ordinary lenses will not. When wearing polarized Sunglasses, looking at reflective surfaces like metal or glass under the sun will significantly reduce the glare.

People knows that sunglasses can block ultraviolet (UV) rays in sunlight. As summer approaches, sunglasses have become one of the essential items in our lives. My friends often ask: Is it necessary to choose polarized sunglasses for outdoor traveling? Today, let me satisfy your curiosity by explaining the differences between ordinary sunglasses and polarized sunglasses, and how to choose between them.

For most people, buying a pair of dark-colored sunglasses in summer is believed to protect the eyes from UV rays. In fact, this idea is incorrect. Ophthalmologists point out that polarized sunglasses are more effective than ordinary ones in summer.

Why are polarized sunglasses more effective? This relates to the properties of natural light. Natural light, also known as unpolarized light, consists of electromagnetic waves that vibrate in random directions. When natural light passes through a polarizing lens, only waves vibrating in one specific direction can pass through. Polarized sunglasses leverage this property to block harmful light.

When sunlight hits any object, it generates harmful light through reflection or refraction. Polarized sunglasses can completely absorb these rays, reducing damage to the eyes. In contrast, ordinary sunglasses lack this function. Their lenses cannot filter light but only reduce the intensity of strong light and UV rays. They are powerless against harmful reflected or refracted light, meaning they can only mitigate eye damage to a limited extent. However, ordinary sunglasses have a significant advantage: their fashionability, which many online buyers favor.

Moreover, sunglasses aren’t just for sunny days. They are categorized into sunshade sunglasses, colored sunglasses, and special-purpose sunglasses. Colored sunglasses can be used for fashion matching throughout the year, while sunshade sunglasses are suitable for all seasons. Even on cloudy days, it’s recommended to check the daily UV index to decide whether to wear sunglasses.

The Burning Question: How do I choose the right frame for me? What materials are available, and what’s the difference between them? Although many have worn eyewear for years, terms like acetate eyewear, metal eyewear, white copper eyewear, tungsten carbon eyewear, and titanium eyewear still leave them confused most just pick based on style and make a purchase without a second thought.

Aoker here to break down their differences in simple terms, so you can easily master the skills to select the right material.

What are the main frame materials?

1. Acetate: The Treasure Material in Eyewear
Scientific name: Cellulose acetate. It has high raw material costs and strict manufacturing process requirements.
Product Features:
Strong texture, rich and glossy colors, warm touch, and hypoallergenic.
Representative Products:
Acetate eyewear is an eco-friendly material that won’t be affected or altered by human skin or bodily secretions. With high transparency, easy dyeing, comfortable touch, and timeless appeal, it offers creative flexibility for processing making final acetate eyewear vibrant and full of character.

2. Tungsten Carbon Eyewear: A High-Tech Material in Recent Years
Widely used in medical, electronic, and aerospace fields.
Material Features:
Flexible and unbreakable, with sweat-resistant surfaces that won’t peel.

3. Metal Eyewear: The Current Fashion Favorite
Metal materials for frames are divided into three categories: copper alloys, nickel alloys, and precious metals.
Material Features:
Wear-resistant, hard, shiny, and fashion-forward in design.
Metal eyewear boasts hardness, flexibility, corrosion resistance, metallic luster, light weight, and comfort, with adjustable nose pads. Materials include nickel silver, stainless steel, titanium, memory metal, aluminum, monel frames, etc. We produce various metal eyewear styles, such as rimless, full-rim, and half-rim frames.

4.Pure Titanium Eyewear: The Noble Material in Eyewear
Titanium is used in aerospace and nuclear power generation, weighing 48% less than ordinary metal frames.

Material Features:
Both flexible and lightweight, non-fading, with delicate and slim designs.

5. Buffalo Horn Eyewear: 100% Natural Material
Purely natural, extremely lightweight, comfortable to wear, pleasant to the touch, and suitable for many with skin allergies.
Horn is a lightweight, comfortable, and beautiful frame material that commands a premium price. While Asian water buffalo horn is abundant, few manufacturers have the skill to transform it into eyewear. Only the most skilled artisans at top frame workshops can cut and polish horn materials to meet the standards of luxury eyewear.

In the summer time, friends who often drive are always troubled by strong sunlight. So, how should drivers select suitable sunglasses from the many types available? How to choose sunglasses? What precautions should be taken when wearing sunglasses while driving? AOKER will explain this to you.

Gradient Color sunglasses Are a Good Option
Wearing sunglasses can block and prevent ultraviolet (UV) rays from harming the retina and eye lens, slowing down or preventing the onset of cataracts. In the sunny summer, citizens should wear sunglasses when going out, but try to avoid wearing them indoors. The principle of moderation should be followed when wearing sunglasses, do not overwear them just for the sake of novelty or fun. Especially for teenagers, sunglasses should not be worn indoors, as indoor visible light stimulates eye development.

Drivers with myopia can first wear contact lenses and then sunglasses. If a driver’s eyes are inflamed and they cannot wear contact lenses, they can wear optical frame with a clip-on sunlens. For drivers without myopia, gradient color sunglasses are recommended, as they change color according to the intensity of UV rays—a relatively user-friendly design. Drivers should avoid wearing dark sunglasses, as these may cause visual delays and pose safety hazards.

At present, sunglasses on the market are divided into light-blocking sunglasses and polarized sunglasses. Generally, drivers can wear polarized sunglasses during the day, as polarized lenses can completely block dazzling glare caused by scattering, reflection, and other factors, effectively ensuring driving safety. Light-blocking sunglasses, on the other hand, are suitable for people who are long-term light-sensitive or have larger pupils and are more sensitive to light.

Extra Caution When Wearing Sunglasses
Although wearing sunglasses can avoid UV damage, drivers should be careful: dark sunglasses may “filter out” light-colored objects in the periphery, causing drivers to have illusions and thus leading to danger. Therefore, when driving with sunglasses, consciously limit speed and observe the driving environment to avoid traffic accidents.

In places with significant light changes, such as tunnel entrances, the same distance may appear closer in strong daylight and farther in dim environments. This can cause drivers to misjudge the length of oncoming vehicles, passing distances, and following distances. Therefore, drivers wearing sunglasses should be more cautious when passing through tunnels to avoid rear-end collisions.
