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.

Today we will take an in-depth look at myopia lens materials. To figure out which myopia lens works best, you first need to learn about different lens types.

Experts classify myopia lenses by material into inorganic materials and organic materials. In terms of development history, they fall into three categories: natural crystal lenses, optical glass lenses and optical resin lenses. Ophthalmologists point out that the best myopia lenses are those that correct vision while providing optimal eye protection.

1. Lens Performance: Blue Light Blocking & Anti-Fatigue
When choosing myopia lenses, evaluate them from three aspects: imaging quality, anti-eye fatigue performance and ultraviolet (UV) protection.
Studies show crystal lenses fail to block UV rays effectively. They contain numerous natural mineral impurities and deliver poor optical imaging, so they have been largely phased out.Glass lenses only block UV light up to 350 nm, while the wavelength range of harmful UV rays is 295–380 nm.Resin lenses can block UV rays within 350–380 nm, and some premium variants offer protection beyond 380 nm.
In addition, various lens coatings are available. Coated lenses feature higher surface hardness and help relieve eye fatigue.

2. Resin Lenses vs. Glass Lenses: Different Functional Features
Glass lenses and optical resin lenses are the two most common options on the market.Glass lenses are hard and highly wear-resistant, with stable quality and parameters over long-term use.
Resin lenses are divided into spherical lenses and aspherical lenses. Compared with spherical lenses, aspherical lenses produce less peripheral aberration, present more realistic vision and look more aesthetically pleasing. Generally, a higher refractive index means thinner and harder lenses.
Resin lenses are much lighter than glass lenses, provide better UV protection and superior impact resistance. For these reasons, optical resin lenses are the better choice, ideal for teenagers, people with high refractive errors and athletes.

3. Price Is Not the Priority — Suitability Matters Most
Ophthalmologists note that the quality of a pair of glasses mainly depends on the lens. Lens prices are determined by brand, imaging performance and coating technology, while frame costs largely decide the overall price of the glasses.

Therefore, the quality of myopia glasses is not necessarily proportional to their price. People with myopia should neither buy cheap glasses at random nor blindly pursue expensive products that do not fit their eyes. It is recommended to get an eye examination at a professional ophthalmic hospital, and pick suitable, cost-effective glasses based on individual eye conditions.

The trend of myopia affecting younger children and developing into severe cases is worsening, and the growing number of children wearing glasses has drawn widespread public attention.
Can these vision rehabilitation centers really help kids ditch their glasses? Reporters recently conducted an on-the-spot investigation into the issue.

Using keywords such as “myopia treatment” and “vision rehabilitation” on Baidu and Dianping, reporters found that there are more than 300 such stores in Beijing alone, including numerous franchise chains. Some youth vision rehabilitation centers have over a dozen branch locations.
The boom in the vision rehabilitation industry is closely linked to China’s persistently high and continuously rising youth myopia rate, as well as widespread anxiety among parents.

According to the latest report from the World Health Organization, China has a total of 600 million people with myopia. The myopia rate among high school and university students exceeds 70%, while nearly 40% of primary school students are nearsighted. China ranks first worldwide in youth myopia prevalence, and the figure keeps climbing year after year. A recent survey of 1,950 parents of primary and secondary school students shows that 73% have children with myopia, and 92% are deeply worried about their kids’ eyesight.

“Half of the students in my class wear glasses, and several suffer from high myopia,” a teacher at a middle school in Beijing told reporters. Today’s children are surrounded by electronic devices, yet they fail to realize how much harm prolonged screen time does to their eyes.

Mr. Xu, a Beijing resident, has a fifth-grade son with nearly 200 degrees of myopia, who now struggles to see the blackboard clearly. Hoping to stop his child from wearing glasses permanently, he took the boy to a nearby vision rehabilitation center. “The staff said they could restore eyesight gradually through device-based and manual massage. Five treatment courses cost 7,000 yuan,” Mr. Xu said. He insisted that his child must not wear glasses at such a young age. “I’m willing to spend any amount on treatment, otherwise he’ll never be able to take glasses off later.”

The person in charge of the center stated that over 100 children have regained their eyesight since its opening. Business peaks during winter and summer vacations, and the center earned hundreds of thousands of yuan in profit last year.

Eager to free their children from glasses, many parents spare no expense on so-called myopia rehabilitation treatments once their kids are diagnosed with nearsightedness. Strong market demand has consequently given rise to a large number of myopia rehabilitation institutions of all kinds.

Which brand of progressive lenses is the best?

This is a subjective question. Optometrists and opticians have their own preferences based on professional experience and patients’ feedback. Below is an objective evaluation of progressive lenses.
Advantages
One prominent benefit of progressive lenses is their integrated prescription design. There are no visible dividing lines on the lenses, nor will you experience image jump. This greatly boosts wearing comfort and enhances safety during activities such as driving. Conventional multiple pairs of glasses and frames mean extra maintenance work and higher costs, which is rather inconvenient. With progressive lenses, you do not need to switch glasses frequently when alternating between computer use, driving and other daily activities.
Even if you rarely use a computer, prolonged exposure to LCD or LED screens can strain your eyes, which makes intermediate vision correction essential. A single progressive lens can correct distance vision, intermediate vision and near vision (for reading) simultaneously — it serves three purposes at once.
Progressive lenses combine multiple visual fields into one lens, with diopter power changing gradually to accommodate far, intermediate and close-range viewing needs.
Disadvantages
Many new wearers encounter minor issues when walking up and down stairs. Since the near-vision correction zone sits at the lower part of the lens, stairs may appear distorted or “bouncing”. This is a normal adaptation issue, and the discomfort usually fades within about two weeks as you get used to the lenses.
Other potential problems often stem from lens materials, surface coatings, improper fitting or incorrect wearing posture, rather than flaws inherent to progressive lenses themselves. Some people simply struggle to adapt to progressive lenses. These lenses are not suitable for everyone, and a small number of wearers can never get accustomed to them. For such cases, bifocal lenses are a better alternative.
Limitations
The visual experience of wearing progressive lenses is often compared to watching movies on a modern high-definition flat-screen TV, instead of an old cathode-ray tube television.
Which brand of progressive lenses is the best?
This remains a subjective choice. Optometrists and opticians select different brands according to their professional experience and patients’ individual conditions.

In daily work, many patients and parents often ask: “Which lens is better? Will certain lens coatings harm the eyes? Do you have blue light blocking lenses?” Today, let’s take a brief look at common coatings for resin lenses.

Early lenses had no coatings. After long-term use, people found that uncoated lenses were prone to scratches and produced glare, which blurred vision. As a result, hard coatings and anti-reflective coatings were developed.

Main Functions of Different Coatings
Hard CoatingResin lenses are lightweight, safe and comfortable, yet they scratch easily with regular use. A wear-resistant hard coating is applied to the surface to enhance the lens hardness.

Anti-Reflective CoatingThis coating leverages the wave properties and interference of light. It effectively cuts down glare, delivering clearer vision.

Top Coating (Anti-Fouling Coating)Lenses with anti-reflective coatings tend to get dirty easily, which lowers light transmittance. An additional top coating is added to repel oil and dirt.

Blue Light Blocking LensThere are two main types of blue light blocking lenses on the market: coating reflection type and substrate absorption type.

Reflection type: The lens is coated with a film that reflects short-wave blue light, giving the lens surface a blue-violet tint.
Absorption type: Special color infiltration technology tints the lens yellow to absorb blue light. Such lenses appear yellowish-brown with a dark coating.
How to Choose the Right Lens Coating
Lens coatings are manufactured through sophisticated processes to provide multi-layer protection. They affect the lens service life, appearance and visual clarity. Generally speaking, coated lenses outperform uncoated ones, and functional coatings work better than regular ones.
Choose coatings according to your personal needs, as the most suitable option is always the best:
People who frequently use electronic devices are recommended to choose blue light blocking coatings.

Primary and secondary school students may opt for peripheral defocus lenses.
Adults should prioritize protection against ultraviolet rays and blue light; photochromic and blue light blocking lenses are great choices.

Hard coatings are ideal for those who value durability and scratch resistance.

Anti-fouling coatings suit people who require lenses to stay clean easily.
Green coating is the most common and standard anti-reflective coating. It offers UV protection and excellent light transmittance, presenting clear, natural and true colors. It is comfortable to wear and perfect for people with high color perception requirements and students.

Do not select lenses merely based on their appearance. Always pick what works best for you.
