Choose the correct pair from the following: (a) Lens - Accomplishes accommodation by changing the curvature of its plane (b) Retina - Holds the lens with the help of the suspensory ligament (c) Cornea - Secretes aqueous humor (d) Choroid - Helps to maintain the shape of the eyeball

Which of the following are the refractive media of the eye? (a) Cornea, aqueous humour, lens, vitreous humour (b) Retina, aqueous humour, lens, vitreous humour (c) Cornea, retina, lens, iris (d) Aqueous humour, iris, vitreous humour, cornea

What is the relation between the lens and the accommodation of the eye?

Blind spot is the part of the eye devoid of light sensitive cells formed at the junction of optic nerve and retina.

Accommodation is the ability of the retina of the eye to adjust the focal length as needed.

Choose the odd word and write it: Hypothalamus, Pons, Medulla Oblongata, Cerebellum

While looking at a distant object the focal length of the ocular lens increases if its curvature decreases.
