I need to know whether wearing spectacles can cause optical harm. I saw a movie where one pair of glasses was placed on table exposed to sunlight, then the sunlight converged and focused to a point and the table started burning, I couldn't believe that, but after that, I learned that fire can be produced by focusing sunlight with a magnifying glass, I was amazed, but I was worried that this may also happen to humans wearing glasses, though our eyeballs don't usually burn like that. Is that possible?
