Should you wear sunglasses while driving?

Anti-glare, safe driving

Sunglasses mainly help to reduce glare and eye strain caused by sunlight, thereby ensuring your safety when driving a motor vehicle. Wearing sunglasses while driving will also prevent the harmful effects of sunlight.

However, drivers need to prepare a type of glasses that is truly suitable for their eye condition. If your eyes are in a normal state, not nearsighted or farsighted, or have no refractive errors or astigmatism, you can choose a regular type of sunglasses. If your eyes are nearsighted or farsighted or have any abnormal signs, you need to go to a professional eyewear store to check and choose the right type of glasses.

Should you wear sunglasses when driving in the rain or at night?

There are also many questions about whether to wear sunglasses when driving in the rain or at night?

In heavy to very heavy rain, the water blurs the windshield and the wipers do not work fast enough, greatly limiting your visibility. Drivers often choose to turn on the headlights to increase the lighting and adjust the wipers as quickly as possible. However, visibility is still not improved much.

On some forums recently, some members have shared a way to increase visibility for drivers in heavy rain or to prevent glare from oncoming headlights at night, which is to wear sunglasses. According to the shares, this method also helps drivers avoid being dazzled by water splashing when two vehicles pass each other, or when your car is behind a large truck or another car in the rain.

It is true that sunglasses can improve your vision in heavy rain. However, this is only true for polarized sunglasses.

Polarized glasses are similar to regular sunglasses, but they have an additional filter inside that blocks horizontal polarized light rays reflected from flat surfaces such as lakes, seas, and highways. If these horizontal polarized rays are not blocked, they will cause eye discomfort and the image will be blurred.

The good effect of polarized glasses on the human eye is to help observe in all conditions of strong sunlight without being dazzled and glared by blocking horizontal rays of light that cause glare. When used at night, it helps drivers not to be dazzled by rays from headlights of oncoming vehicles, street lights... For the same reason, wearing polarized sunglasses will filter out horizontal rays of light caused by refraction through the rain, helping the driver see better. These glasses also work well when used in strong sunlight conditions, or driving during the day in dense fog.
