Sunglasses are essential
It's the hottest season of the year again. For those who drive, with the air conditioner on in the car, the human body is comfortable, but the eyes are still suffering - the strong sunlight outside the car affects the sight, and it is easy to make the eyes tired after a long time. Therefore, it is necessary to prepare a pair of suitable sunglasses to avoid eye irritation from strong light.
It is best to wear polarized sunglasses when driving. Because polarized sunglasses have a very high blocking rate of ultraviolet rays, even if the eyes look directly at the strong light for a long time, it is not easy to get tired. At the same time, it also has the function of filtering out scattered light and anti-glare that ordinary sunglasses do not have.
Some car manufacturers have launched original sunglasses in recent years, which are polarized lenses with anti-ultraviolet and anti-glare. It should be reminded that if you are driving some models with a head-up display and wearing polarized sunglasses, the normal reading of the display information may be affected or even completely invisible because the polarized light is "too in place".
The price is not the only criterion for judging whether the quality of a pair of sunglasses has passed the test, but how much can explain the point. The price is ridiculously low, and it may be difficult to guarantee the quality itself, let alone polarizers. Generally speaking, if the price is much lower than 100 yuan, it is basically not an authentic polarizer.
In addition to the price factor, the outer packaging of regular UV-blocking sunglasses is marked with a UV protection rating (UV). UVA (filterable ultraviolet wavelength is 320-420 nanometers), UVB (filtering wavelength is 275-320 nanometers) and UV400 (filtering wavelength is within 400 nanometers), all of which have anti-ultraviolet functions.
The color of the sunglasses for driving should not be too dark. It is best to choose brown or gray polarizers, and dark green ones are also recommended. The tinted lenses can filter out a lot of blue light, which can improve visual contrast and clarity. The gray lens can evenly absorb any color spectrum, and what you see after wearing it will only darken without obvious chromatic aberration.
When driving in summer, choose a pair of beautiful and qualified polarized sunglasses for yourself!
