Know the Sun’s effect on eyes

We’ve studied UV in our childhood. Now, let’s dig a little deeper to understand how it can affect our vision. UV rays are high-energy invisible light rays that are emitted from the sun. UV can be split up into three different types; UVA, UVB, and UVC.- UVA rays have higher wavelengths, hence can pass through glass easily.
- UVB rays are the most dangerous radiation, which causes melanoma, and also results in damaging the Retina.
- UVC rays are absorbed by the atmosphere, so are not a threat to our eyes.
