Question

Identify the correct pathway of light-

• A. Cornea $\to$ aqueous humour $\to$ vitreous humour $\to$ lens $\to$ retina
• B. Lens $\to$ cornea $\to$ aqueous humour $\to$ vitreous humour $\to$ retina
• C. Cornea $\to$ lens $\to$ aqueous humour $\to$ vitrous humour $\to$ retina
• D. Cornea $\to$ aqueous humour $\to$ lens $\to$ vitreous humour $\to$ retina

Answer 1

The correct option is D Cornea $\to$ aqueous humour $\to$ lens $\to$ vitreous humour $\to$ retina

The correct pathway of light is:

Cornea - aqueous humour - lens - vitreous humour - retina

The cornea forms one-sixth of the anterior portion of the eyeball. It admits and focuses the light rays entering the eye.

The space between the cornea and the lens is called aqueous chamber and is filled with a fluid called aqueous humour. It is responsible for the nutrient supply to the lens and cornea.

The lens bends light rays as it passes through it. It changes its shape and adjusts such that the light waves focus on the retina.

The vitreous humour is the fluid found in the vitreous chamber, a space between the lens and retina. It helps maintain the shape of the eyeball.

So, the correct answer is option 'd'.

The retina is the neurosensory layer of the eyeball.
