16
Q

A form of anisometropia in which one eye is myopic and the other hyperopic

A

Antimetropia

17
Q

It is a condition in which the refractive power of the two eyes is unequal.

A

Absolute Anisometropia

18
Q

It is that type of refractive anomaly in which although the total refraction of the two eyes is equal, the component elements in each show relatively large differences.

A

Absolute Anisometropia

19
Q

this is commonly referred to as lazy eye.

A

Amblyopia

20
Q

this is when a person is not able to align both of their eyes under normal conditions simultaneously and is referred as being cross eyed.

A

Strabismus
