Myopia

Myopia is a condition where the vision outlined for the first time by Aristotle (384-322 BC. JC) a myopic blur seen by far, and next to the visual defect, myopia some abnormalities are accompanied by more or less serious the retina.

Definition.

It speaks of myopia if the image of distant objects is formed in front of the retina. The importance of myopia varies eyes.

In near vision, there is a distance at which a myopic sees net and without effort. If myopia is important, this distance is reduced. This is why some people very nearsighted read a few inches of text.

We know the different causes of myopia.

Either the eye is “too long” (a look “normal” has a length of 23mm). This is the case in congenital glaucoma. This rare disease can reach children at birth. Because of increased pressure in the eye, the eye grows too quickly and becomes fragile. Without treatment, the evolution is toward blindness. It should make the diagnosis as soon as possible.

Either the optical system of the eye (formed by the cornea and lens) is too powerful.

Finally, make certain myopic cataracts.

Evolution.

Myopia usually appears around adolescence and may increase to about 20 years. It is not known to predict how fast or how long it will increase, because each eye is different.

The myopia “strong” in principle occurs earlier and may even rise well after age 20.

Consequences eye.

Without glasses, myopia is not a good distance visual acuity. It is expressed in tenths. If the eye is in good condition, the glasses allow him to see 10/10, or even more.

Myopia have a greater risk to a detached retina or glaucoma. For detection, regular visits to the ophthalmologist are recommended.

Some say myopia “strong” are responsible for abnormalities of the retina that worsens over time and threaten vision. The physician can monitor their progress in examining the funds.

Some children are visual too much effort: they “accommodate” too. This can result in “false myopia. To recognize and find the cause is instilled into the eyes eye drops that temporarily block the accommodation and we review the child.

Optical correction.

The myopic lenses have been used since the 15th century.

Myopia is corrected by a glass diverge. He puts on the retina, the image of distant objects, which are seen as sharp.

Avoid too correct myopia, which may cause eyestrain and headaches. Some are intentionally under-corrected to improve the comfort of the subject, even at the expense of a moderate vision blurred.

Different types of glasses and materials exist. The optician can guide the choice.
