What brand of cycling glasses is good

Riding glasses are different from sunglasses. Never use sunglasses when riding. Riding glasses have more windproof effect than sunglasses. Don't underestimate this function. It can greatly reduce your risk of conjunctivitis. So the general good riding glasses, when the riding speed is too fast, the eyes can't feel the wind. In addition, glass is not allowed to be used as lens information for riding glasses, because it will greatly enhance your ability to get injured when you fall, while resin can protect your glasses from scratch. Here are some information about sunglasses to introduce the choice of riding glasses.

There are five kinds of sun lens: anti reflective protective lens, colorful lens, colored lens, polarizing lens and color changing lens.

Anti reflective protective lens: this kind of lens is coated with a thin layer of magnesium fluoride on the surface to avoid strong light reflection, so that you can see things more clearly and not disturbed by strong light. To test whether your glasses really choose anti reflective protective lenses, you can aim your glasses at the light source. If you see purple and green reflections, it indicates that the lenses are indeed coated with anti reflective protective film.

Colorful lens: also known as "dyed lens", it is to add some chemical substances in the lens manufacturing process to make the lens appear color, so as to absorb light of specific wavelength. This is the most commonly used lens type for sunglasses.

Color lens: the effect of this lens is the same as that of colorful lenses. The only way to make it is different. It is to apply color to the surface of the lens. What we know most is "gradually colored lens". The color is the deepest one on it and then becomes lighter down. Generally, the sunglasses with power are mostly treated by coloring.

Polarizing lens: in order to filter the glare of the sun on the water, land or snow in the same direction, the special coating on the lens in the vertical direction is called polarizing lens. It is most suitable for outdoor sports (such as sea sports, skiing or fishing).

Color changing lens: also known as "photosensitive lens". Because the chemical substance of silver halide is involved in the lens, the original transparent and colorless lens will become colored lens when exposed to strong light for protection, so it is suitable for indoor and outdoor use.

Sunglasses colorful lenses without color effect and effect:

In addition to the differences in materials, the following describes the effect and effect of different color lenses of sunglasses.

Gray film: the gray lens can evenly absorb any chromatogram, so the viewing phenomenon will only darken, but there will be no obvious color difference, showing the real natural feeling. It belongs to neutral color system.

Tan lenses: filter out a lot of blue light, can improve the visual contrast and clarity, in the case of severe air pollution or foggy wear effect is better. Generally, it can block the reflection light on the smooth bright surface. The wearer can still see the thin and thin, which is the ambition choice of the driver.

Green lens: in the absorption of light together, the maximum increase in the green light to reach the eyes, so there is a cool sound feeling, suitable for people with slightly tired eyes.

Gray Lens: similar to gray lens, both belong to neutral lens, but the color is deeper and the visible light absorption rate is higher.

Silver lens: the surface of the lens is coated with high-density mirror. This kind of lens absorbs more visible light and is suitable for outdoor sports.

Yellow lens: strictly speaking, this kind of lens does not belong to the sun lens, because it hardly reduces the visible light, but in foggy and evening, yellow lens can advance the contrast and provide more accurate vision, so it is also called night vision mirror. Some young people wear yellow lenses "Sunglasses" as decoration.

Light blue, light pink and other lenses: also more decorative than practical lenses.

Dark green lenses: absorb heat, bring cool feeling, but the light transmittance and clarity is low, suitable for wearing in the sun, not for driving.

Blue lens: you can wear sun blue lens when you play on the beach. Blue can filter the light blue reflected by the sea and sky. You should avoid using blue lenses when driving, because it will make us unable to distinguish the color of traffic signals.

Transparent lens: transparent lens is actually a little light yellow, because it is lighter, so it is called transparent lens. It can be used as wind mirror or rain proof mirror.

For us, the main effect of glasses is to suppress ultraviolet rays, which can greatly induce our risk of cataract. The strength of anti ultraviolet rays has nothing to do with the color of our lenses, but with the lens information and film. All the above colors should have the defense ability of uv380 or above, otherwise they will be replaced no matter how dark the color is.

Types of coating:

General coating: the mercury like coating on the sun lens, some shallow, some deep, depending on the degree of shading you need. If the sun is very general, the deep and deep coating is the same as the shading glass on the car window.

SFM coating: the color has general mercury / Rainbow / Blue / and gold mercury, highly anti-wear, with 6 layers of new information, clearer and glossy than general electroplating.

Lens appearance: adhere to the original color, especially the light color and progressive color, the effect is clear, very simple to see the original color of things, the lens is glossy, looks very smooth, not like the general mercury is dim. In particular, after mercury plating, the fluoroscopy rate of the original film remains unchanged or slightly changed by 1-2%, reducing reflection and increasing soundness. If the quality of mercury film is not good, the fluoroscopy rate will be significantly reduced and there will be glare, so that the wearer can see his own eyes from the back of the film.

AR coating: myopia or some high quality glasses will choose, it is a combination of multi-layer extremely thin inorganic compounds, the use of preemptive machine imitation vacuum plating. Sunglasses are often plated on the back of the film is not good. It can forward light perspective, clear sound visual sense, reduce reflection, forward night vision, reduce fatigue, reduce computer radiation.

Revo mercury: it's colorful mercury. Generally, sports glasses are used. There are blue revo/ black red revo/ green revo/ orange revo/ it is plated by 8-12 layers of extremely thin mercury, so it is relatively expensive, it has very good anti solar radiation effect, colorful color can match the color of glasses
