Question

Which of the following parts of the eye are responsible for refraction and focusing?

• A. Cornea
• B. Aqueous humour
• C. Lens
• D. All of these

Answer 1

The correct option is D

All of these

Light rays reflecting from distant objects enters the eye through the cornea, aqueous humor, the lens, and finally the vitreous humor. Light entering the eye is refracted by the cornea. About 80% of the refraction occurs in the cornea and about 20% in the inner crystalline lens. The lens focuses light and images formed on the retina.
