Our eye lens is a __________.
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Convex lens
The eye lens is a transparent, flexible lens that is thicker in the middle than at the edges, with both faces curved outward. Such a lens is a convex (converging) lens: it bends the light coming from an object so that it meets on the retina and forms a real, inverted image there.
The ciliary muscles change the curvature of the lens, so its focal length changes and the eye can focus on both near and far objects.
