Question

Arrange the parts of the human eye in the correct sequence of arrangement starting from the outermost part.

• A. Cornea
• B. Pupil
• C. Lens
• D. Retina
• E. Optic nerve

Answer 1

Light enters the eye through a transparent layer called cornea which is the outermost layer. It then passes through the aqueous humour and enters the pupil. It then passes through the lens and then strike the sensitive inner layer called retina. The retina recieves light from the lens and converts it into neural signals. And finally the optic nerves transmits the neural signals to the brain for visual perception.
