It is a common observation that a magnifying glass when used to converge rays of sun to a fine point in paper, the paper burns due to intense heat.
Why doesn't this happen in our eyes? Our eyes are also doing the same, they are converging the sunlight into our retina but our eyes don't get burned, or to say get heated.
Is viterous or aqueous humor absorbing heat? If so, then the tiny amount of fluid present in the eye shouldn't be enough to cool the eye for a longer period of time, but we can spend the entire day at sunlight without any eye stress or pain.
Size of eye lens small compared to magnifying glass? However a magnifying glass of the size of eye lens should also be able to produce significant heating by converging sunlight.
As far as I know, the heating effect is due to Infrared rays not because of UV rays so we can safely ignore them in this case, right?
