Power of Accomodation

Read the assertion and reson carefully to mark the correct option out of the options given below: Assertion : The eye is said to have power of accomodation . Reason : Ciliary muscles alters the shape of the lens for near or far vision during accomodation .

A myopic adult has a far point at 0.1 m . His power of accomodation is 4 diopters. (i) What power lenses are required to see distant objects ? (ii) What is his near point without glasses ? (iii) What is his near point with glasses ? (Take the image distance from the lens of the eye to the retina to be 2 cm).

The human eye possesses the power of accommodation. This is the power to :

The defective condition of accomodation of the eye in which distant objects are seen distinctly but near objects are indistinct is

A convex lens of power 4D is kept in contact with a concave lens of power 3D, the effective power of combination will be

Assertion :- Accomodation power is present in human eye. Reason:- It depends on the sliding of lens forward and backward

Assertion :- Accomodation is done by Iris of eye. Reason:- Lens is biconcave and flexible in nature and ciliary body muscles does not help for this process.

Does short sightedness (myopia) or long sightedness (hypermetropia) imply necessarily that the eye has partially lost its ability of accomodation ? If not, what might cause these defects of vision ?
