Question

Here is an experiment: At the hottest point of the day, go to a sunny area with a magnifying glass and a sheet of paper. Hold the magnifying glass wide out with the lens facing the sun. Keep the paper behind the lens. Now, adjust the position of the paper and the lens, and at a particular position, you can see the paper burning at a spot. This is because the light rays from the sun are parallel. When they reach the lens, they converge at a point called the focus. And when the paper falls on the focus, all the light rays get concentrated on that point, along with all that heat energy, and hence causes the fire.

When we consider our eye, the lens is also like a magnifying glass and the retina is like our sheet of paper.

Here's my question - when parallel light rays enter the eye, they converge on a point on the retina. Why doesn't the retina catch fire?

Answer:

Actually our retina have protecting layers which doesn't let our retina face any problem..

there are ciliary muscles in our eye, which helps our eye to dialate and contract.

(Intraocular lens (IOL): After cataract surgery, the cloudy lens will be replaced with an intraocular lens (IOL). The lens naturally protects the eye from almost all ultraviolet light and some blue light. There are types of IOL that can protect the eye and retina from blue light.)
