1.2 What is Hyperopia ?
Hyperopia is often referred to as "long-sightedness" or "far-sighted".
An eye is hyperopic when the far point is at a virtual point behind the eye.
Generally the hyperopic eye is too short with respect to the refractive state
of the standard eye (ie an emmetropic eye or eye requiring no optical
correction) or because the optical power of the eye is too low relative to
the length of the standard eye. The focus is correctly adjusted using a
"plus" lens power or convex lens.
