What brand of cycling glasses is good

Riding glasses and sunglasses are not necessary. Never use sunglasses during riding. Riding glasses have more windproof effect than sunglasses. Don't underestimate this function. It can greatly reduce your risk of conjunctivitis. So usually 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. The following is a brief introduction to the selection of riding glasses based on the sunglasses found by Wu Yue.

The types of solar lenses are roughly divided into:

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

Anti reflective protective lens: this kind of lens is coated with a thin layer of magnesium fluoride to prevent 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 means that the lenses are indeed coated with anti reflective maintenance film.

Colorful lens: also known as "dyed lens", that is, in the lens manufacturing process, some chemicals are added to make the lens appear color, so as to absorb the light of a specific wavelength. This is the most commonly used lens type for sunglasses.

Color lens: this kind of lens has the same function as the colorful lens, but the method of making it is different. It is to paint the color on the surface of the lens. We are most familiar with the "gradiently colored lens". The color is the deepest on the top, and then gradually lighter down. Usually, the sunglasses with power are mostly treated by coloring.

Polarizing lens: in order to filter the sun shining on the water, land or snow in the same direction of the eye-catching light, in the lens to participate in the straight direction of the special coating, called polarizing lens. 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 added to 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 do not need the function and function of color:

In addition to the differences in raw materials, the following describes the role of sunglasses with different colors.

Gray film: the gray lens can evenly absorb any color spectrum, so the viewing scene will only darken, but there will be no significant 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 better. Usually, it can block the reflection light of the smooth and bright appearance, and the wearer can still see the slim part clearly. It is the ideal choice of the driver.

Green lens: in the absorption of light, the maximum limit to add green light to the eyes, so there is a cool and comfortable feeling, suitable for people with simple and tired eyes.

Gray Lens: similar to gray lens, it belongs to neutral lens, but with deeper color and higher visible light absorption.

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 almost does not reduce the visible light, but in foggy and dusk time, yellow lens can improve 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 are low, suitable for sun exposure, not suitable for driving.

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

Tong Ming lens: Tong Ming lens is actually a little light yellow, because the contrast is shallow, so it is called Tong Ming lens. It can be used as wind mirror or rain proof mirror.

The most important function of glasses for us is to block ultraviolet rays, which will greatly induce the risk of cataract. The strength of anti ultraviolet rays has nothing to do with the color of our lenses, but with the information and film of the lenses. The above colors should have the defense ability of uv380 or above, or they will be replaced no matter how deep the color is

Types of coating

Usually coating: that is, the mercury like film 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 is usually mercury / Rainbow / Blue / and gold mercury, highly abrasion resistant, with 6 layers of new information, clearer and glossy than usual plating.

Lens appearance: adhere to the original color, especially the light color and progressive color, the effect is clear, it is very simple to see the original color of things, the lens is glossy, looks very comfortable, not like the usual mercury contrast dim. In particular, the original perspective of the film after mercury plating remains unchanged or slightly changes by 1-2%, reducing reflection and adding comfort. If the quality of the mercury film is not good, the fluoroscopy rate will be significantly reduced, and there will be glare, which will cause the wearer to 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, using leading machines to imitate vacuum plating. Sunglasses are often plated on the back. It can improve light perspective, clear and comfortable visual sense, reduce reflection, improve night vision, reduce fatigue and reduce computer radiation.

Revo mercury: that is colorful mercury. Usually sports glasses
