The prolonged port of the contact lenses is another cause; in fact, the dryness of the eyes is the most current complaint among the users of contact lenses. The results of a recent research indicate that the port of the contact lenses and the dryness of the eyes can become a vicious circle.

Blur of astigmate

Myopia or presbyopia is well known but it is more difficult for each one, even for the carriers of glasses to define astigmatism. This one isn’t necessarily insulated; because it can combine with hypermetropie, myopia or presbyopia.

This problem of sight is caused by an eye at the slightly oval form. Usually, the cornea is smooth and have the same curve in all the directions. With astigmatism, the curve is more marked in a direction than in other. This difference in curve of eye thus makes difficult the formation a clear image. The vision finds itself fuzzy or deformed.

A marked astigmatism is generally hereditary, congenital and, often, it doesn’t varying during existence. A light astigmatism can be acquired constantly; this is a very current problem which, when it is light, often doesn’t require correction.

Astigmate suffers of a vague vision of near like by far. The images are duplicated.
Possible consequences: headaches, tiredness, eyes red, feelings of burns or tuggings.
These problems can be accentuated if astigmate works in a context which requests much the vision of near. This is the case of people who works on computer.

Try to make read a poster with a astigmate and you will see that they confuses close characters. The ophtalmologist, with the traditional test of recognition of the figures and letters, will note easily that the patient confuses 0 and 8, N and M.

Correction

The person who fears to suffer astigmatism or tests the symptoms of them must go in an ophtalmologist who will subject it to examinations. If the distortion occurs in a regular direction, the correction is easy. Often, the doctor will prescribe the wearing of adapted glasses.

If the distortion is irregular, the cornea will have to be refashioned. This correction carry’s out by use of rigid lenses or the grafts it human corneal tissue. The rigid lenses are often more effective in this case but some special soft lenses can correct a light astigmatism. If astigmatism is important, it couldn’t be corrected by means of lenses always likely to waver on the unequal cornea. In this case, a special lens known as toric could be ground in order to obtain a curve on former surface, thus making it possible to stabilize the lens on the cornea.
