Why is it harmful to see solar eclipse with naked eye?
Doctors always warn people, especially children, against watching the solar eclipse, either directly or through smoking glasses or even in shallow water as in a utensil. The harmful rays in the sunlight (infrared rays) are at the maximum during the eclipse, which might burn the most sensitive part of retina, forea and macula, leading to irreversible loss of eyesight.
The surface of the sun is about four times as hot as a furnace. The lens or cornea in our eyes acts like a burning-glass. If one looks straight at the Sun, the lens will be destroyed for life. Even if we look at the Sun through smoked glass, the Sun may look dim, but the dangerous heat rays can still pass through. Whenever there is an eclipse of the Sun, some people are blinded because they take foolish risks of this sort.
