Preface:

First of all, I want to thank my cool friends for their support during this time

Many cool friends have asked me a lot about lensesShoppingI've finally had some free time recently, so today I'll share with fellow cool friends how to choose lenses and advice on lens brands, and I'll try to express myself in the simplest and most understandable way. So I wrote this article hoping to encourage brothers who wear glasses!!

 

(The text and images are quite long, so it's recommended to bookmark and read.)

 

 

1. Knowledge related to lensesPopular science

Let's first talk about some knowledge about lenses, such as the mainstream lens materials, types, refractive index, Abbe number, spherical versus aspherical surfaces, and other related issues on the market.

(1) Lens material

Currently, there are three mainstream types of lenses (glass element, resin element, and cosmo element).

Glass shards

Advantages: Good light transmittance, durability, and long lifespan

Disadvantages: heavy and fragile, not suitable for rimless glasses, poor UV protection.

Resin sheets:

Advantages: medium light transmittance; mainstream glasses currently use resin sheets, which offer excellent UV protection

Disadvantages: Ages quickly; after two or three years, it tends to turn yellow.

Universe films:

Advantages: Durable, not broken

Disadvantage: Poor light transmittance.

(2) Types of lenses

There are many types of lenses on the market. Besides the single-vision lenses commonly worn by myopic people, there are also some more functional lenses, blue light protection lenses, anti-fatigue lenses, anti-fog lenses, and more.

We mainly talk about single-vision lenses, which are our mainstream ordinary lenses.

(3) Refractive index

This parameter is one of the important indicators when choosing lenses. Understanding it mainly allows us to know the thickness of the lens.

Mainstream common refractive indices: 1.56, 1.60, 1.67, 1.74

The higher the refractive index, the thinner the lens and the higher the price.

The lower the refractive index, the thicker the lens, and the lower the price.

(4) Abbe number

Currently, Abbe number is also one of the key indicators of lens optical performance, mainly reflecting the lens image quality.

Currently, this indicator is mostly a theoretical value for ordinary people; the human eye can perceive it very low, so we won't elaborate further here.

Moreover, mainstream brands with the same refractive index lenses generally have similar Abbe numbers, so there's no need to worry too much about this indicator.

5) Spherical and aspherical surfaces

Currently, there are three types: spherical, aspherical, and double aspheric.

The advantages of aspheric lenses include significantly reduced edge aberration, less distortion around the lens, and a more natural and aesthetically pleasing eye area—these are the mainstream advantages today.

 

Spherical images are rarely seen now, as aberrations can change, leading to distorted peripheral vision and unstable image quality.

 

Double aspheric lenses can be achieved in only a few brands, but they are difficult to manufacture and usually expensive. Of course, all indicators are better than aspheric types, making them suitable for people with ultra-high myopia.

2. How to choose lenses that suit you

Based on my years of shopping experience, the most important things are to look at!!

Look at budget, alcohol consumption, and needs

You can refer to my previous article: first, you must check your own budget and act within your means—better to be the head of a chicken than the tail of a phoenix.

(1) Check the budget

Whatever your budget is, choose the brand you choose. There's really no need to force yourself into Zeiss or Essilor.Cost performanceGood options like Seete Nai and Kaimi are also great choices! Take it slow

(2) Check the prescription

If the prescription is high, choosing a high refractive index (1.67 or 1.74) will also result in a higher price.

For lower prescriptions, choose low refractive index (1.56 to 1.60), which usually results in a cheaper price.

So many people wonder why the difference is so much higher than (1.74 yuan vs. 1.67), which involves a lot of issuesTechnologyThe difference is truly significant. (I'll explain this part in detail when I have time)

For power and refractive index, you can refer to the chart below

 

(3) Assess demand

Finally, consider whether you have other needs, such as blue light protection, fatigue resistance, or specialized lenses for driving, adding functional features.

 

Summary: Choose which brand of glasses based on your budget, and then choose the refractive index that suits you based on your prescription. Finally, check if you have any special needs

Brothers with steamed buns are a different story!!

 

 

3. Mainstream Lens Brand Recommendations (Zeiss, Essilor, Cami, Mingyue)

Currently, mainstream lens brands include Germany's Zeiss, France's Essilor, Korea's Kemi, Japan's HOYA, Seiko, Donghai, etc., and domestic brands like Mingyue.

Here, I won't talk about everyday life, only the mainstream

 

。 Here, we mainly recommend Zeiss, Essilor, Camie, and Mingyue.

Zeiss and Essilor are basically among the industry's top tier, while Cami has always had a good reputation, making it the king of value for money. Our domestic Mingyue is also quite reliable. There's another product I have to mention: Zeiss's Vision, which performs very well in all aspects of lens imaging [Leeuwenhoek][Leeuwenhoek].

1: Zeiss

—— Zeiss A Series ——

Entry-level lenses use domestic materials, basically domestic materials, moderate price, and use Zeiss lotus film with low hardness. Not highly recommended!

3. Kaimi

Here, I'll only talk about the U2 and U6 series, and I don't recommend buying them because of the origin and the market is quite chaotic

——U2 Series——

It mainly features high-definition lenses and UV protection, offering good value for money. Its dust and water resistance is decent, easy to clean, dirt-resistant, and wear-resistant—all aspects are decent.

——U6 Series——

It blocks blue light and UV rays. The front surface uses lens material to block UV projection, while the back uses a UV anti-reflective film to reduce UV reflection. It offers great value for money. The U6's background color is relatively lighter than other domestic brands. If you want blue light protection but mind the base color, the U6 should be your first choice.

4. SeeTena

It's a sub-brand of Zeiss, with good clarity and anti-submarine capability. It's a product produced on the Zeiss production line, and its quality easily beats all domestic brands. For friends with a budget of just a few hundred meters, this is the right choice. Personally, I also recommend this one

——Ultra-smooth high-definition coating HMC+

Increased hardness, easy care, wear-resistant and non-slip, clear and comfortable, waterproof and oil-resistant

——Blue Light Protection Coating——

On top of HMC, an additional layer of blue light blocking film is added. The film is blue-purple in color. Not only does it ensure hardness and clarity, but it also blocks harmful blue light, and the base color is lighter than the U6. Definitely worth buying.
