Hyperopia
The opposite of myopia, hyperopia appears when the eyeball is too short to establish an image on the cornea. As a result, there is a clearer image behind the cornea. Distant objects are clear while there is blurring close up. Contact lenses increase the ocular power, permitting clear vision of close-up objects.
Here is how the spherical contact lens corrects hyperopia:
|
The irregular shape of the cornea produces two focusing points of light in front of or behind the retina, resulting in blurred vision.
|
 |
|
The toric lens corrects the refractive light and in this way creates a focal point on the retina where the vision is clear.
