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
