Contemporary ways of correction of myopia


Nearsightedness or myopia will be the head from the ranking of sight troubles. With this particular sickness, someone ceases to plainly distinguish things at extended distance, he has to squint, shift the words closer to his eyes. Simultaneously, your eyes strain, get worn out, which more improves the negative diopters. What strategies are there right now to enhance aesthetic acuity?


Sunglasses


The most ancient and many wide-spread approach to raising eyesight in case of myopia. Everyone knows by investing in moderate myopia (as much as -3. diopters), eyeglasses are tried not to be recommended for continuous dress in. Because glasses, restoring visual acuity, weaken the eye muscles, and this contributes to the growth of myopia, they are used only when necessary.


Glasses are prescribed for constant wear, because vision is reduced to the point where glasses can no longer be dispensed with, with myopia more than 3. diopters. With higher myopia (more than 6. diopters), in choosing the potency of the lenses, your physician prescribes not just a complete correction, but the so-called endurance correction, i.e. one that the person tolerates. Concurrently, somebody fails to see completely in cups. The intolerance of full spectacle correction for myopia is associated with many reasons, but the main one is a significant reduction in the image due to spectacle lenses.


It is not easy to get used to eyeglasses when myopia is put together with astigmatism (this can be some deviation of the cornea of ? ?the eye through the shape of a sphere as well as an approximation towards the shape of an ellipsoid). In this case, sophisticated glasses with cylindrical glasses are assigned. Correction with glasses of anisometropia (distinct eye potential of two eyeballs) is another significant problem. The intolerance of full correction in cases like this is assigned to the formation of photos of different sizes in the retina, that the mental abilities are incapable of merge in to a single total. The human head on its own fights this problem, deflecting the badly viewing eyesight aside (therefore squint develops) or decreasing the aesthetic acuity of merely one eye (the so-called "lazy eyesight" or amblyopia grows). This situation brings about issues that demand long term therapy to bring back perspective.

Sluggish eyesight also builds up in young preschool children with imperfect correction of higher myopia. Low eyesight in this instance is just not reconditioned, and the achievements of the treatment will be the far better, the previous a whole eyesight correction is recommended.


Contact lenses


It must be observed that the majority of these problems are properly resolved by contacts. She does not exclude the use of glasses as an additional means of vision correction, however. A contact lens, in contrast to eyeglasses, is located straight on top from the eyeball and it is separated in the entrance top of the eyesight only from a covering of tears. As a result of shut refractive indices in the substance from which the get in touch with tears, cornea and lens are produced, the lenses forms one particular visual program with the vision. With this system, the eye muscle tissues serve as within a wholesome eyesight, and weakened accommodation is qualified, which is one of the causes of the progress of myopia. Thus, contact lenses for myopia are not only a means of correcting vision, but also a means of treatment.
