Question

the eye lens is a)double convex lens b)double concave lens c)plano-convex lens d)plano concave lens​

Answer 1

Answer:

Explanation:

. A lens having both the spherical surfaces curved

inwards is a concave lens.

Answer 2

Eye Lens is DOUBLE CONVEX (option a)

• The eye lens is a transparent lens present in between the anterior and posterior segment of the eye.

• It is responsible for proper focussing of light rays originating from both distant and nearby object.

• The light race undergo refraction from both the cornea as well as from the lens and gets focused on the retina.

The eye lens is a double convex lens with an approx power of 16-19 Dioptres and the cornea has a power of 44-45 Dioptres.

Since the power is positive, the lens is converging in nature.
