Can you go blind at staring at UV light?

More serious damage is known as solar retinopathy. This occurs when UV light literally burns a hole in the retinal tissues. It destroys the rods and cones of the retina and can create a small blind spot in the central vision, known as a scotoma.

What is a Snowblind?
