Explanation:
The process of refraction of light is important in the functioning of the human eye. The refraction of light occurs at different structures of the eye, but most of the refraction occurs at the outer surface of the cornea.
Cornea:
The cornea is the transparent outer layer of the eye that covers the iris, pupil, and anterior chamber. It is the first structure that light rays encounter when entering the eye. The cornea plays a crucial role in the refractive power of the eye. It is responsible for providing about two-thirds of the eye's total refractive power.
Crystalline lens:
The crystalline lens is a transparent, biconvex structure that is located behind the iris. It is responsible for providing one-third of the eye's total refractive power. The lens can change shape to adjust the focus of light on the retina. This process is called accommodation.
Iris and Pupil:
The iris is the colored part of the eye that surrounds the pupil. The iris controls the size of the pupil, which regulates the amount of light that enters the eye. The pupil is the black circular opening in the center of the iris. It allows light to enter the eye and reach the retina.
Conclusion:
In conclusion, although refraction of light occurs at different structures of the eye, most of the refraction occurs at the outer surface of the cornea. The cornea plays a crucial role in providing about two-thirds of the eye's total refractive power.
