Are Polarized Sunglasses Better?

Do night driving glasses really work?

Yellow lenses reduce the amount of light entering your eye, reducing visibility. These darker colors block more blue light than yellow lenses. But they block more light from entering the eye, reducing visibility even more in low-light conditions. In fact, even yellow lenses reduce overall visible light to some extent because they block some blue light. This can be a good thing during the day, but not at night, when maximum visibility is key. Night driving glasses come in a variety of yellow and amber colors. The darkest lenses filter out the harshest light, but they filter out the largest amount of light, making it difficult to see in dim or dark conditions. Some people who wear night driving glasses say they can see better with them on. However, vision tests have shown that night driving glasses do not improve night vision, nor do they help drivers see pedestrians any faster than they would without glasses.

Why do you need night-driving glasses?

Aging causes our pupils to become progressively smaller, so they don't dilate as quickly. A smaller pupil means less light reaches your retina, which makes it harder to see at night. The weak artificial light, and the fact that we can't see beyond these sources in the dark, exacerbate the dangers of night driving. For people wearing prescription glasses, the risk of driving at night is much greater. Driving can be stressful, especially if you have poor eyesight. This is especially true at night. If you have poor vision and drive at night, you're vulnerable to a number of potential hazards, and we're talking about prescription glasses for night driving. These glasses can play a big role in making you safer and more comfortable. They can even save your life. This is especially important as night vision decreases with age. When you drive at night, choosing the best prescription glasses for night driving can make your life easier.
