Your problem > Vision problems > Far-sightedness


Far-sightedness is not a disease but a vision disorder or, more scientifically, a refraction disorder. As such, far-sightedness has three “cousins”: short-sightedness, astigmatism and presbyopia.

Contrary to short-sightedness, where the eye is too long, in the case of far-sightedness the eye is too short and the light rays meet behind the retina, whereas they should normally focus on the retina.

A young patient is not aware of his problem, as his eye lens’ efforts to adjust – still supple – enable this far-sightedness to be compensated by re-centring the light rays on the retina. But with age, the eye lens loses its elasticity and far-sightedness progressively becomes apparent. Then the eye adjusts poorly to short distances and a patient has to wear reading glasses sooner than other people of his age. In time, he will also have to wear glasses for long distance vision.

What are the symptoms?

A person with far-sightedness sees blurred close up but clearly far away, at least if the patient is still young. From a certain age a person with far-sightedness sees blurred under all circumstances and will tend to wear glasses all the time.

Far-sightedness may also cause headaches or concentration problems, especially in the evening. The eyes may become red or feel they are burning.

Who is affected?

Although young people have far-sightedness, it often becomes apparent with age: it normally appears between 35 and 50 years of age. It affects more than 25% of the population.

What are the causes?

Generally, far-sightedness is hereditary.

What is the evolution?

Far-sightedness appears right from birth. When a patient is young he spontaneously compensates his far-sightedness by adjustment efforts. But with age, and depending on his degree of far-sightedness, his efforts become insufficient and a patient will have to wear glasses firstly for close vision then for long distance vision.

From 45 years of age, presbyopia adds itself to far-sightedness, which means a patient has to wear a different correction to see close-up and long distance.

How is it diagnosed?

Far-sightedness is diagnosed by a clinical examination by an ophthalmologist.

How can it be prevented?

Unfortunately there is no way of preventing far-sightedness.

how to treat it?


    Deep treatment with LASIK

    In depth treatment with FemtoLASIK

    Surface treatment by photorefractive keratectomy (PRK) with the Excimer Laser

    Surface treatment with LASEK (Laser-assisted sub epithelial keratomileusis)

    EPI-LASIK surface treatment

    Treatment with “artisan” phakic implants

    Treatment by refractive exchange of the crystalline lens
