Glasses help people with myopia see the world clearly, making them truly a great invention. Today, glasses are no longer just a tool for vision correction, but also a fashionable accessory for daily styling. So how do you pick the right eyeglass frames?

Frames are chosen based on the geometric shape of facial bone structure. Faces are generally divided into six types: long face, square face, round face, inverted heart face and oval face. Different face shapes suit different styles of frames.

1. Long Face
People with long faces have an elongated silhouette and a sharply defined jawline.
Recommended material: Mainly acetate plastic
Recommended style: Full-rim frames
Styling tips:
Go for frames with soft square or rounded outlines
Choose frames with a large vertical height
Select frames with low-set and wide temples
Opt for solid dark-colored frames

2. Square Face
Square faces feature a broad forehead, a short facial outline and soft cheek lines.
Recommended material: All materials are suitable
Recommended style: Full-rim, brow-line and half-rim frames
Styling tips:
Pick oval frames or square frames with gentle curves
Choose frames with slim and minimalist lines
Go for frames with a small vertical height
Select frames with high-set and narrow temples

3. Heart Face
Also known as inverted heart face, it is wider at the top and narrower at the bottom, creating an unbalanced visual effect.
Recommended material: Mainly acetate plastic
Recommended style: All frame styles
Styling tips:
Choose frames that are narrower on the upper part
Pick frames with a large vertical height
Select frames with high-set temples

4. Round Face
Round faces have full cheeks, a relatively wide forehead and a rounded chin, with soft overall contours.
Recommended material: All materials are suitable
Recommended style: All frame styles
Styling tips:
Choose frames with distinct, firm angles
Go for frames with a small vertical height
Select frames with high-set temples
Pick frames with elevated nose pads
The core principle of frame selection is to highlight your facial strengths, conceal flaws, and create a symmetrical and balanced look. Since everyone has a unique face shape, choosing frames that match your features can refine your facial contours and enhance your personal charm.

Do you feel overwhelmed when picking eyeglass lenses? There are glass lenses, nylon lenses, resin lenses, plus lenses with refractive indices of 1.56, 1.61 and 1.67. How do you make the right choice?

Lens Materials
1. Glass Lenses
Made primarily of optical glass, they feature excellent optical properties and a high refractive index. A higher refractive index means a thinner lens. However, glass lenses are fragile and relatively heavy. For daily use, they are cumbersome to wear and easy to break, so they are not widely used nowadays.

2. PVC Plastic Lenses
PVC is a type of thermoplastic material. Solid PVC is heated and molded into lenses. Such lenses are low-cost, but they have poor light transmittance, low heat resistance and are prone to deformation. They are mostly used for decorative glasses. Despite the low price, PVC lenses are not recommended for long-term daily wear.

3. Nylon Lenses
Nylon lenses are made of transparent polyamide. Thanks to its special physical properties, the material was initially applied to spacesuit visors, police and military anti-explosion gear, and precision instruments. Due to the high cost, civilian nylon lenses are mainly used for professional sports protective eyewear and luxury sunglasses. They come with a hefty price tag for ordinary consumers, while they are a casual pick for the wealthy.
Note: Many cheap lenses on the market claim to be nylon products. They are actually made of common polyamide, which looks similar but is not genuine nylon material.

4. Resin Lenses
Resin lenses are optical lenses made from resin, available in coated and uncoated versions. They are lightweight, impact-resistant and deliver good light transmission. Coated resin lenses see great improvements in waterproof performance and wear resistance. Additional functional coatings can also be applied to provide UV protection, blue light blocking and photochromic effects.
Today, resin lenses account for 99% of all lenses sold in optical shops. Basic uncoated resin lenses are also known as “white lenses” at a low price. The price of coated resin lenses varies according to coating techniques and additional functions.
Spherical vs. Aspherical Lenses: Which Is Better?
The two types differ in surface curvature. Traditional spherical lenses cause severe aberration and distortion, leading to blurry vision, distorted views and a narrow field of vision.
Aspherical lenses correct these flaws effectively. Meanwhile, they are lighter, thinner and more stylish.

Advantages of Aspherical Lenses
Sharper vision: With professional coatings, they deliver clear and comfortable visual experience.
Lightweight to wear: You can barely feel the lenses on your eyes.
Natural view: They minimize visual distortion and present realistic scenes.
Given people’s pursuit of life quality and appearance nowadays, aspherical lenses are highly recommended for their light weight, thin profile and attractive look.

Lens Refractive Index
The numbers 1.56, 1.61 and 1.67 stand for lens refractive index, a core parameter of eyeglass lenses.
Differences Between 1.56, 1.61 and 1.67 Lenses
For lenses of the same material and power, a higher refractive index results in a thinner lens. Lenses with a higher refractive index cost more to produce and process, so the larger the number, the higher the price.

Under the same material, power and curvature design, a 1.56 lens is thicker than 1.61 and 1.67 lenses. For people with high myopia, high-index lenses reduce overall weight and look more appealing. Besides, aspherical lenses are thinner than spherical ones even with the same refractive index.

For most people, coated aspherical resin lenses are the top choice, as the technology is mature, the price is reasonable and they are comfortable to wear. Luxury lenses are an option for those with a higher budget.
Guidance on Choosing Refractive Index
Below 200 degrees of myopia: Choose 1.56
200 to 400 degrees of myopia: Choose 1.61
Over 500 degrees of myopia: Choose 1.67

After going through the above classification and comparison, you will have a basic understanding of lenses. Next time you visit an optical shop, you can select suitable lenses based on your own needs and avoid unnecessary spending.

Do lenses have an impact on visual clarity?
Yes, they do.

Here we need to introduce a key parameter for evaluating lens clarity: Abbe number. A higher Abbe number means sharper imaging, while a lower one results in blurred vision. Generally, the higher the lens refractive index, the lower its Abbe number. The Abbe number is primarily determined by the lens material itself. Some brands add special additives to improve the Abbe number. A small number of lenses that balance high Abbe number and high refractive index have also emerged on the market.

For ophthalmic lenses, the Abbe number normally ranges from 30 to 60. Lenses with a refractive index of 1.50 from mainstream brands have an Abbe number of around 58, whereas those with a refractive index of 1.74 have an Abbe number of about 32. A friend of mine has worn both types. Currently she uses lenses with a refractive index of 1.60 and an Abbe number of 40. She says the visual difference between Abbe numbers 58 and 32 is quite noticeable, yet she can barely tell the difference between 40 and 58.

Conclusion
If you have a high diopter: Prioritize thin and lightweight lenses with a relatively high refractive index, but do not over-pursue an extremely high index.
If you have a low diopter: Go for lenses with a higher Abbe number, since clear vision is the top priority.

Are there fixed standards for selecting lens materials?
No. The choice depends on personal needs and budget.
The two main lens materials are glass and resin. Resin lenses are further divided into thermoplastic materials (represented by PC lenses) and thermoset materials (represented by CR39 lenses).

Unlike eyeglass frames, resin lenses are the mainstream choice among consumers. Thanks to continuous technological improvements in recent years, thermoset resin lenses are favored by most people for their well-rounded performance.

Though PC lenses are not naturally scratch-resistant, manufacturers apply protective coatings during production to reinforce their durability, so this is no longer a major concern for buyers.

With the widespread use of electronic devices, people’s eyesight has been deteriorating. Myopia affects increasingly younger children, and presbyopia now occurs at an earlier age. Various eye conditions have also become more prevalent, leading to a sharp rise in the number of people wearing glasses.

Common lens coatings include green coating, gold coating, magenta coating, blue coating and yellow-green coating. Blue coatings deliver excellent radiation resistance and wear resistance, yet their light transmittance is lower than that of green coatings. Green coatings feature superior light transmittance but are less wear-resistant than blue ones. Radiation-proof lenses are covered with a blue anti-radiation coating. When you tilt and rotate such lenses, a distinct blue iridescent glow can be seen on the surface.

Hard Coating
Silicon dioxide hardening technology is applied to the lens surface, bringing its wear resistance close to that of glass lenses.

Anti-Fouling Coating
Mainly made of fluorides, this coating covers the porous anti-reflective layer. It reduces the contact area between the lens and water or oil, so water droplets and grease hardly stick to the surface. It is also known as a water-repellent coating.

Anti-Radiation Coating
This coating consists of metallic compounds that form a protective barrier on the lens. Following the electromagnetic interference shielding principle, a conductive film is applied via specialized coating techniques. It reflects and absorbs low-frequency radiation and microwave radiation, relieving potential eye heating caused by low-frequency radiation and preventing visual fatigue.

UV Protection Coating
It blocks harmful ultraviolet rays in sunlight.

Many people still hold the long-standing belief that the eyewear industry is highly profitable. With the rise of online shopping platforms such as Taobao, Tmall and JD, intense price competition has made eyewear pricing fully transparent. The industry is no longer synonymous with excessive profit margins. Even so, pairs that look nearly identical can vary greatly in cost. Today, we will compare cheap and high-end models by taking pure titanium frames as an example.

These two styles share roughly 80% of the same design and base materials, yet there are clear gaps in quality and price.
1. Temple Design
Most wearers encounter a common problem: frames that fit too tight cause headaches and leave deep indentations on the temples. Loose frames, on the other hand, keep slipping down and require constant adjustment.
Aoker has optimized this detail by adopting high-elasticity memory material for the temples. The temples flex automatically to fit different face shapes, eliminating pressure marks on the temples and delivering all-day comfort.

2. Upgraded Fitting Accessories
Screws: Aoker uses advanced glue-reinforced screws. They boost friction, withstand frequent opening and closing, extend service life and effectively prevent screw thread slippage.
Nose Pads: Our exclusive custom nose pads are contoured to fit the curves of the left and right sides of the nose. They sit snugly to reduce pressure marks on the bridge of the nose for a more relaxed wearing experience.
We have also launched the 3rd-generation summer-specific metal nose pads. Designed with special grooves, they accelerate sweat evaporation and stop frames from sliding easily.

These subtle details account for the price gap between eyewear products. We will continue to share more differences in our future posts.

Prolonged work in front of computers has caused visual fatigue in many people. Nowadays, quite a number of people wear anti-fatigue lenses. However, most overlook a key detail: they assume any frame works for these lenses. In fact, specific rules apply if you want to achieve the optimal anti-fatigue effect. Let’s take a closer look.

Causes of Binocular Visual Fatigue
When the eyes focus on distant or near objects, the ciliary muscles relax and contract to adjust the thickness of the eye lens. The ciliary muscles stay relaxed for distance vision and contract for near vision. Excessive eye use or prolonged close-range viewing keeps the ciliary muscles in a sustained contracted and tense state, which may lead to accommodative spasm — namely visual fatigue.

Working Principle of Anti-Fatigue Lenses
Designed to relieve fatigue caused by continuous ciliary muscle contraction, anti-fatigue lenses adopt a principle similar to progressive lenses. They add a +0.50 D to +0.60 D accommodative power to optimize myopic diopters, restore normal minor diopter fluctuations and rebalance the eye’s accommodation system. This fully eases strain on the eyes.

To put it simply: the lens has a higher power for distance vision and a lower power for near vision, with diopters gradually decreasing from the center to the edge of the lens.

Frame Selection for Anti-Fatigue Lenses
Given the gradual diopter change across the lens surface, frame height is a critical factor. If the frame is too short, the effective visual area will be limited. Both near and distance vision will rely on the same diopter zone, and the anti-fatigue function will be largely ineffective.

For anti-fatigue lenses, the vertical height of the frame should preferably be no less than 30 millimeters. That said, an excessively tall frame is not ideal either. Always pick a suitable frame based on your own diopter.
