Hyperopia develops in eyes that focus images behind the retina instead of on the retina, which can result in blurred vision. This occurs when the eyeball is too short, which prevents incoming light from focusing directly on the retina. It may also be caused by an abnormal shape of the cornea or lens.

Farsightedness can be corrected with glasses or contact lenses to change the way light rays bend into the eyes.
If your glasses or contact lens prescription begins with plus numbers, like +2.50, you are farsighted.
You may need to wear your glasses or contacts all the time or only when reading, working on a computer or doing other close-up work.
When selecting eyeglasses for the correction of farsightedness, choose aspheric high-index lenses — especially for stronger prescriptions. These lenses are thinner, lighter, and have a slimmer, more attractive profile. Aspheric lensesalso reduce the magnified "bug-eye" appearance eyeglasses for hyperopia often cause.
Be aware, though, that high-index aspheric lenses reflect more light than standard plastic lenses. For the best comfort and appearance, make sure the lenses include anti-reflective coating, which eliminates distracting lens reflections.
High-index aspheric lenses for children should be made of lightweight polycarbonate lensmaterial for superior comfort and impact resistance.
Also, photochromic lenses that automatically darken in response to sunlight are highly recommended for kids and anyone who spends a significant amount of time outdoors.
Refractive surgery, such as LASIK or CK, is another option for correcting hyperopia. Surgery may reduce or eliminate your need to wear glasses or contact lenses.
