What would happen if a blind person looked at the sun?

Once absorbed into the retina, the UV rays result in the formation of free radicals. They ultimately destroy the rod and cone photoreceptors in the retina. The oxidative damage is referred to as solar or photic retinopathy. Damage can occur in as little as a few seconds of staring directly at the sun.

How do blind men see?

Can a legally blind person have a pupillary reaction?

Pupil reaction in a legally blind patient. It depends whether the nerve that regulates pupillary constriction was affected by the injury or stroke which also blinded the person. You can be blind from an occipital stroke because your brain no longer processes input from your optic nerve, and have no problems with pupils reacting.
