Myopia is a visual defect that affects distance vision causing general blurred vision of objects that are far away or if there is a very high myopia even objects close to 50 cm are not seen well either.
CAUSES
People who suffer from myopia have a more elongated curvature of the eyeball or the corneal or crystalline lens structure has a different curvature than a person who does not suffer from any visual impairment and causes the light coming from outside to focus not exactly on the retina but in front of the retina. For this reason, the vision is blurred. The function of the glasses is to put the image coming from the outside in focus on the retina.
Myopia can appear at birth, in childhood or in adolescence. It does not appear very often in adulthood, but there may be cases. Several studies have shown that there is a progressive increase in the number of people with myopia, especially in children.
METHODS TO STOP MYOPIA
There are several methods to try to stop myopia in the child to adolescent stage:
- Lenses to stop myopia: It is a lens designed to stop the development of myopia in children. It is a treatment that must be taken into account especially in children of early ages where it is analyzed that year after year myopia is increasing. It is necessary to go to a specialist in optics to diagnose the case and assess whether this type of glass is suitable.It must also be taken into account that there are many causes of myopia, and one of them is genetics. This type of glass does not permanently eliminate myopia but it slows it down and it is very important because it is not the same for a 7 year old child with a myopia of -3 diopters to end up at 16 years of age with a myopia of -7 diopters than to end up with a myopia of -5 only. The difference is great and it should be noted that any treatment that helps to reduce myopia is good.
.
- Contact lenses to stop myopia: they have the same function as glasses. Like glasses, it is a treatment to slow the growth of myopia and not to eliminate it.Contact lenses are a useful option just like glasses, although in children it is not used as much due to the maintenance of contact lenses and hygiene which are very important. It is also important to know that contact lenses to stop myopia must be worn for many hours for the treatment to be effective.
- Visual therapy: these are a set of exercises that help to improve the muscular function of both eyes equally. After a good diagnosis and depending on the type of myopia that exists, they can give positive results. It is efficient especially in children.
- In conclusion, the treatments that exist for myopia are to correct it or to stop its fast development. There are cases, but very rare, in which the myopia that appears disappears, especially in special cases such as pregnancy or an episode of stress.
