Question

Which of the following best describes the nature of our lens?

• A. Biconvex, opaque and adjustable
• B. Biconcave, crystalline and stationary
• C. Biconvex, crystalline and adjustable
• D. Biconcave, opaque and stationary

Answer 1

The correct option is C Biconvex, crystalline and adjustable

Lens is a crystalline, biconvex and an adjustable structure which bends the light rays. It separates the aqueous humour and the vitreous humour. Ciliary muscles and suspensory ligaments attached to the lens relax or contract to adjust the shape of the lens. This adjustment of lens is necessary to view objects at different distances and to focus light rays on the retina.
