Facts about harmful UV rays

UV rays are harmful rays that are produced by the sun. They’re broken into three different types: UVA, UVB and UVC. Both UVA and UVB rays reach the Earth and are dangerous to our eyes, but UVB light is the most dangerous. Since these rays are produced by the sun, they can be stronger when it’s highest in the sky. That means rays are most harmful between 10 a.m. and 2 p.m., but you still need protection throughout the whole day.

Many people believe that they’re only at risk on sunny summer days, but that isn’t true. Since the rays are capable of passing through clouds, you also need to wear sunglasses when it’s overcast. Surprisingly, snow can reflect up to 80 percent of UV light, which means that these rays are still damaging even in the dead of winter.

Although UV rays can harm your vision in any weather, keep in mind that UV light can be increased by humid conditions, which means it’s easier to get UV damage when you’re on the coast or somewhere else that’s humid.
