Benefits of Wearing Sunglasses on Snowy Days

For driving, wearing sunglasses is not just about blocking out the harsh sunlight, it is directly related to driving safety. Many people wear sunglasses when driving, but not everyone will know the reasoning behind it.

The benefits of wearing sunglasses on a snowy day

Firstly, when driving we are trying to focus on what is ahead of us. In addition to the sun's glare, there are also reflections from the road and the rear windscreen of the car in front of us. So if you don't have sunglasses to cover your eyes, it's easy to get eyestrain. In addition, your eyes will not be able to adjust instantly to the light and dark environment, which will affect your driving safety.

In addition to the hot summer sun, it is also necessary to have sunglasses in winter. On snowy days, the environment in front of you is white. It can be very difficult for your eyes to adjust to dark areas. This is often referred to as "snow blindness".

What is snow blindness?

"Snow blindness is also known as heliophthalmia. It is caused by the burning of the outer cornea of the eye by ultraviolet radiation after the reflection of bright light from large areas of snow. In bright light conditions, the snow reflects much more ultraviolet light. A large amount of UV light is absorbed by the cornea of the eye and the eye will develop damage similar to electro-optic uveitis. Typical symptoms are dry eyes, tearing, gritty foreign body sensation, severe pain and conjunctival congestion.

It is important to beware of snow blindness on snowy days. Wearing sunglasses is not only fashionable, but more importantly, it can prevent snow blindness.
