The role of driving sunglasses

During driving, there are various reflected light and glare from different objects (such as water glare and headlight glare). The polarizer can filter out unnecessary light, make the line of sight clearer, and drive safer. % blocks harmful light. Gray or dark green lenses, which are the most natural choice when viewing objects, are good choices.

Material for driving sunglasses

Lens: Polarized lens, in line with relevant standards, such as UV protection should be above 99%, not easy to break.

Frame: aluminum-magnesium alloy, pure titanium, etc.

Principle of driving sunglasses

Driving glasses are designed according to the precise optical principle of the lens polarization angle and curvature. Only the light with the same polarization direction is allowed to pass, while other strong light sources (such as the sun, water surface, glass, and asphalt pavement) are filtered because of the polarization direction after reflection, thus eliminating Excessive light interference, avoiding eye, glare, glare, etc., makes the line of sight more clear and supple.

What are the misunderstandings of driving glasses?

Myth 1: The darker the color, the better.

Many people take it for granted that the deeper the color, the better the UV protection. In fact, the function of filtering ultraviolet rays from sunglasses is only related to the plated film, and the color is not as deep as possible. Especially for long-distance drivers, if the sunglasses are too dark, the eyes are more prone to fatigue, and it is more dangerous to enter the tunnel and other places where the light is dim.

Myth 2: polarized lenses are the most suitable

Many drivers like to wear polarizers. Indeed, polarizers can reduce glare, eliminate glare, and soften the line of sight. However, polarizers are more suitable for large-area reflective environments such as fishing and skiing, while drivers sometimes face tunnels. In darker scenes, the polarizer is easy to make people suddenly black. In addition, the polarizer will lighten the color of the LCD screen and LED traffic lights. Therefore, when selecting a polarizer, it is best to choose a good quality optical lens, and when passing through the tunnel, it is best to remove the glasses in advance and blink more.

Myth 3: Do not wear myopia

Some drivers have mild myopia, and it is okay to drive without wearing myopia. But once you wear sunglasses, the problem comes: the eyes are more prone to fatigue, and your vision will drop, just as your night vision will be affected. Therefore, the driver with slight myopia has no problem driving normally. If you want to wear sunglasses, you must have a lens with myopia.

Myth 4: The color of the sunglasses is too fancy

Fashionable young people will have sunglasses of various colors. It is not fake, but it is not suitable for driving, such as pink and purple lenses, which will change color and spectrum. In fact, it is best to use gray lenses for sunglasses, because the basic chromatogram will not change. Followed by dark green. The brown and yellow lenses have the effect of increasing the brightness, and are more suitable for environments such as foggy and dusty.
