Should you wear sunglasses while driving?

Combat glare, drive safely

Sunglasses have the main function of limiting glare caused by sunlight, thereby ensuring your safety when driving. Wearing sunglasses while driving also helps to prevent the harmful effects of sunlight.

Wearing sunglasses while driving helps protect your eyes from glare, making driving safer.

However, drivers need to prepare a type of sunglasses that is suitable for their eye condition. If your eyes are in a normal state, without nearsightedness – farsightedness or any refractive errors, you can choose a regular pair of sunglasses. But if you have nearsightedness – farsightedness or any abnormal signs, you need to go to professional eyewear stores to have your eyes checked and choose the appropriate sunglasses.

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

There have also been many questions about whether you should wear sunglasses when driving in the rain or at night.

In heavy rain conditions, when the windshield is blurry and the wipers are not working fast enough, greatly limiting your visibility, drivers often choose to turn on the high beam to increase illumination and adjust the wiper button as fast as possible. However, the visibility is still not greatly improved.

On some forums recently, some members have shared a way to improve visibility for drivers when it is raining heavily or to prevent glare from oncoming headlights at night, which is to wear sunglasses. According to their sharing, this method also helps the driver avoid eye glare when water splashes when two vehicles pass each other, or when your car is behind a large truck or another car in the rain.

Indeed, it is true that sunglasses can improve your visibility when driving in heavy rain. However, this is only true for polarized sunglasses.

Polarized sunglasses are similar to regular sunglasses but they have an additional polarizing filter inside that blocks horizontally polarized light reflected from flat surfaces such as water, beaches, and highways. If these horizontally polarized rays are not blocked, they will cause discomfort to the eyes and the image will be blurred.

The good effect of polarized sunglasses for human eyes is that they help with perfect observation in intense sunlight without glare, by blocking horizontally polarized light. When used at night, they help the driver not be blinded by the bright lights from oncoming headlights, street lights, etc. It is also because of this reason that wearing polarized sunglasses will filter out the horizontally polarized light that is caused when it is reflected through the rain, helping the driver to see better. These sunglasses are also effective when used in bright conditions or when driving during foggy days.
