Four misconceptions of wearing sunglasses while driving

There are four major misunderstandings about wearing sunglasses when driving,some veteran drivers may not know.When we drive on the road at ordinary times, it is inevitable that we will encounter particularly strong sunlight and even driving against the light.Many people will certainly buy a pair of sunglasses, which can not only reduce the damage from the glare and ultraviolet rays to the eyes, but also more clearly see the scenery and road conditions ahead.However, there are many kinds of sunglasses on the market.It is likely to buy sunglasses that are not suitable for driving.

Many people take it for granted that the darker the color, the stronger the ability to prevent strong light and ultraviolet rays.In fact, the function of sunglasses to filter ultraviolet rays is only related to the coating, but not the depth of color.

Not all sunglasses can protect the eyes. A pair of qualified sunglasses can not only block the transmission of ultraviolet rays, but also well distinguish traffic lights of different colors.Unqualified sunglasses may have undesired diopter.It is equivalent to wearing a pair of near-sighted or farsighted glasses when people with normal vision wear these sunglasses.And their eyes will be greatly affected.

In addition, the police suggest that drivers who often wear sunglasses should not choose sunglasses with too large frame and excessive weight. Such sunglasses will make the driver's face swell and paralyze, and distract the driver's attention. It is reported that polarized sunglasses that can filter glare (especially harsh light) are a good choice for drivers. Polarized sunglasses also have the functions of weakening strong light, anti-fatigue, not interfering with vision, anti-ultraviolet and so on.

Sunglasses with beautiful colors are OK to wear when playing, but not suitable for driving. They not only can’t insulate the glare of the sun, but also cause poor vision due to the quality of the lens.
