Night vision is chiefly a function of the:

A tendency of one eye to deviate upward is:

A condition in which the refractive error of one eye significantly differs from that of the other and where both eyes have the same sign (i.e. both eyes are myopic or hyperopic) is known as:

The condition in which the ability to accommodate for near vision becomes inadequate because of loss of elasticity of the crystalline lens is called:

A refractive error in which the rays of light do not come to a single point of focus is called:

While reading, or performing other near vision tasks: 1. The pupils constrict  2. The eyes converge  3. The crystalline lens accommodates  4. The stroma contracts

The condition in which the crystalline lens of the eye gradually loses its transparency with consequent loss of visual acuity is known as:

The photosensitive receptors of the retina which are responsible for sharp visual acuity and color perception are the:
