Why is it dangerous to look through a lens at the sun or a bright light and why we should not focus sunlight with a convex lens on any part of our body?

Solution

Dear Student,

A convex lens can focus the sunlight to a point to such an intensity that can burn paper, wood, plastic, etc. This intense light can easily damage and distort our eye lens. So, it is dangerous to look at the sun through a convex lens.
