Detailed explanation-1: -You can’t see a person’s cornea the way you can see the colored part of the eye behind it-the cornea is like a clear window that focuses light into the eye. Behind the cornea is a watery fluid called the aqueous humor.
Detailed explanation-2: -Crystalline Lens: The transparent structure inside of the eye located directly behind your iris. The sole function of your lens is to focus light rays onto the retina. Fovea: forms a small indentation at the centre of the macula and is the area with the greatest concentration of cone cells.
Detailed explanation-3: -Lens (also called crystalline lens). The transparent structure inside the eye that focuses light rays onto the retina.
Detailed explanation-4: -The cornea refracts light and accounts for two-thirds of the eye’s total power. The lens is a biconvex, transparent structure present in the eye behind the pupil. The lens along with the cornea refracts the light, so as to focus it on the retina.
Detailed explanation-5: -The lens sits behind the iris and is clear and colorless. The lens’ job is to focus light rays on the back of the eyeball-a part called the retina (say: RET-i-nuh). The lens works much like the lens of a movie projector at the movies.
