What is myopia?
Myopia, or nearsightedness, is a refractive error, which means that the eye does not bend or refract light properly
to a single focus to see images clearly. In myopia, close objects look clear
but distant objects appear blurred
. Myopia occurs when the eyeball is too long and the light coming in does not focus directly on the retina
. Myopia may also occur when the cornea is abnormal. Myopia causes a deficit of visual acuity and can cause headaches, strabismus
, visual discomfort and eye irritation.
Myopia is an eye focusing disorder
, not an eye disease.
It can only be considered a disease, when it exceeds a certain graduation, which in this case would be high myopia. Myopia can be developed in childhood
, between 6 and 8 years of age
and it is usually stabilized over 18 years.
Types of myopia
There are two types of myopia. The first one is simple myopia (which is not considered a visual disease) which is less than 6 diopters. The second one is high myopia, when the patient exceeds 6 diopters, it is then an eye disease.
In order to correct simple myopia, it must be first detected by an ophthalmologist, and then, the patient should wear glasses and contact lenses.

How is it corrected?
Myopia can be corrected by the technique of refractive surgery
or Lasik technique
. This laser surgery modifies the shape of the cornea to give the patient proper vision
again. This intervention eliminates the use of glasses and contact lenses definitively. For those patients who due to the characteristics of their eye, does not support laser correction, myopia can be also eliminated by implanting an intraocular lens, which consists of placing a lens in the eye without replacing the natural lens.
