What causes far-sightedness?
When the eyeball is too short.
With far-sightedness (hyperopia), objects at distance appear clearly, on the other hand at close distance they appear blurred. The reason for this is that incident light rays are focussed not directly on the surface of the retina but behind it since the eye-ball is too short. The shorter the eye-ball the weaker the eye sight - that is the person is far-sighted close objects appear more and more blurred.
How to treat far-sightedness?
Treatments for a life without glasses
For the correction of hyperopia there are surgical possibilities within the cornea (cornea resp. Laser treatment) and the eye lens ( lens treatment):
With the laser treatment, tissue of the cornea is eliminated in order to compensate the refraction of the incoming light rays. This requires a certain thickness and stability of the cornea.
With the lens treatments, an artificial lens is inserted in order to alter the refraction behaviour. Lens treatments allow the compensation of very substantial visual defects as there is no limitation regarding the removing of corneal tissue.
Depending on the kind of visual defect, there are several treatment possibilities.
Which treatment is suitable for me?
Eyes differ. Depending on the state of the eye and the type of hyperopia there are different methods.
In principle the following treatment methods can be used for correcting hyperopia:
Hyperopia up to + 10 dpt.
up to 5,0 dpt.
