Hyperopia (hi-pur-OH-pee-uh), also known as farsightedness, is a common visual condition where close objects appeared blurred, but objects farther away are clearer. Farsightedness is caused by the eye structure itself, rather than an underlying eye disease.
Hyperopia often occurs when an eyeball is smaller than normal. It may also occur when the eye’s optics are insufficiently strong for its overall length. When an eyeball is small or its optics are weak, light rays from near objects do not focus properly on the retina at the back of the eye. The result is blurred vision for near objects, but relatively better vision for distant objects.
Presbyopia, which has symptoms similar to hyperopia, is due to an entirely different cause related to the aging process.
