    Nearsightedness or myopia is definitely the leader inside the rating of perspective troubles. With this illness, somebody ceases to clearly identify things at very long ranges, he needs to squint, shift the written text closer to his eyeballs. As well, your eyes pressure, get exhausted, which further more increases the bad diopters. What approaches are there any right now to improve graphic acuity?


    The oldest and the majority of wide-spread approach to improving eyesight in the event of myopia. Everyone understands by using minor myopia (up to -3. diopters), cups are tried to not be suggested for constant use. They are used only when necessary, because glasses, restoring visual acuity, weaken the eye muscles, and this contributes to the growth of myopia.

    With myopia more than 3. diopters, glasses are prescribed for constant wear, because vision is reduced to the point where glasses can no longer be dispensed with. With good myopia (more than 6. diopters), when selecting the strength of the lenses, the physician prescribes not really a complete correction, but the so-called threshold correction, i.e. one who the individual tolerates. Simultaneously, a person does not see completely in eyeglasses. 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 become accustomed to cups when myopia is along with astigmatism (this can be some deviation in the cornea of ? ?the attention in the form of a sphere plus an approximation to the shape of an ellipsoid). In cases like this, complicated sunglasses with cylindrical sunglasses are given. Correction with glasses of anisometropia (various optical potential of two eyes) is yet another serious issue. The intolerance of complete correction in this case is associated with the development of pictures of various measurements in the retina, in which the mental abilities are incapable of merge in to a single total. A persons human brain itself battles this problem, deflecting the badly viewing eye to the side (therefore squint grows) or reducing the graphic acuity of one eye (the so-referred to as "very lazy vision" or amblyopia develops). This situation contributes to issues that demand long term remedy to regenerate vision.

    Slack eye also develops in young preschool children with incomplete correction of substantial myopia. Low vision in such a case will not be repaired, and the success of the remedy is definitely the better, the previous a whole vision correction is approved.

    Disposable lenses

    It ought to be documented that most of these problems are properly resolved by disposable lenses. However, she does not exclude the use of glasses as an additional means of vision correction. A contact lens, in contrast to glasses, can be found directly at first glance of the eyeball and is also divided in the front side top of the vision only by a level of tears. Due to shut refractive indices of the substance from where the contact tears, cornea and lens are manufactured, the lenses types one particular visual process together with the eyesight. Within this method, the eye muscle tissues function as in a wholesome eye, and weakened lodging is trained, which is amongst the reasons for the progression of myopia. Thus, contact lenses for myopia are not only a means of correcting vision, but also a means of treatment.
