Common visual disorders
MYOPIA
The eye of a short-sighted person is "too long", which means that the light ray focuses ahead of the cornea, instead of on it. In some exceptional cases, myopia is due to a lens that is ‘too convex’ and which can cause excessive convergence.
Symptoms: Vision is clear in close proximity, but blurred from afar.
Possible treatment :
- Refractive surgery
- Glasses or contact lenses
HYPEROPIA
A hyperopic person has an eye that is "too short" or where the cornea is too flat.
Symptoms: Vision is blurred in close proximity. It also becomes blurred from afar with age. Depending on the degree of hyperopia, some patients should consult an ophthalmologist at a very young age.
Possible treatment :
- Refractive surgery
- Glasses or contact lenses
PRESBYOPIA
Presbyopia is a widespread visual defect that normally becomes pronounced from the age of 45. Over time, the crystalline lens of the eye loses its elasticity, which prevents it from correctly focusing on images.
Symptoms: Near vision becomes blurred.
Possible treatment :
- Refractive surgery
- Glasses or contact lenses
