How can sunlight damage your eyes?

Answer 1

The sunlight will burn the retina and cause permanent damage and scaring.

The sun is an intense source of energy that will burn and scar the retina due to its intense heat. This is similar to what happens when you focus the image of the sun on a piece of paper with a magnifying glass; the heat is strong enough to ignite and burn the paper. The lens in the eye will focus and intensify the sunlight onto the retina.

UV radiation can cause damage to the cells of the eyes over time, increasing the risk of vision problems and eye diseases. Photokeratitis (sunburn of the cornea), macular degeneration, and cataracts are just a few of the conditions that can result from excessive exposure to UV radiation from sunlight. To protect your eyes, wear sunglasses that block UV rays and avoid prolonged exposure to bright sunlight, especially between 10 a.m. and 4 p.m.
