Vision Needs
Far-Sighted
Farsightedness, or hyperopia, occurs when an eyeball is too short
for the focusing power of the lens and cornea. This causes light rays
to focus behind the retina. As a result, the eye sees distant objects
more clearly while near objects appear blurred. It is a condition in
which your eye is underpowered. Correction requires a "plus" lens
containing additional optical power to permit sharp vision of near
objects.
How a spherical contact lens corrects hyperopia?

|
The shape of a hyperopic eye focuses images behind the retina, producing blurred vision of near objects. |
By
increasing the cornea's focusing power, a spherical contact lens
corrects the refractive error, creating a single focal point on the
retina where vision is sharpest. |
