What is hyperopia?
Hyperopia is a refractive disorder of the eye in which light is focused behind, instead of on the retina. This results in close objects appearing blurry, while far objects may appear normal, leading the eyes to tire easily or not see very clearly near or far.
What causes hyperopia? Main causes:
- reduced refractive power of the eye (refractive hyperopia)
- reduced sagittal axis of the eye (axial hyperopia)
- heredity
Hyperopia usually occurs at birth. It may show a decrease during adolescent and post-adolescent years due to greater adaptability of the eye lens and may start to appear again at the age of 30-35.
Diagnosis
A diagnosis of hyperopia is made after an eye examination performed by an ophthalmologist.
Treatment
Hyperopia may be treated with:
- vision glasses
- contact lenses
- refractive surgery
- surgery for replacing the crystalline, natural eye lens
