Perforating glasses simulators are used for vision correction and are plastic or metal frame with plates of opaque black plastic with multiple round holes. Often in common parlance they are called – perforated goggles – because of a peculiar kind. Causes of visual impairment can be very diverse. This can be either congenital defect or a genetic predisposition to disease, and acquired as a result of excessive visual load, poor lighting workplace, as well as due to general weakness and provoked other chronic diseases, defects in food adverse environmental conditions for living. In addition, the decrease in visual acuity may be associated with age-related changes – in particular, after forty years down the focusing ability of the eye and starts the development of farsightedness. Perforating glasses simulators are used to treat the following cases: visual Surge (eye fatigue) false and true myopia hyperopia asthenopia (accommodative and muscle), photophobia In addition, perforating glasses are used in some cases for prevention. In particular, well relieve tension and eye fatigue after a long visual stress in children and adults (preschool children, schoolchildren, students, teachers, computer operators, fans of tv display, computer games, etc.). Points provide relaxation and rest the eye muscles and create conditions for eliminating the general body fatigue, distraction attention, drowsiness.
A good preventive measure such points will be and for those whose heredity in myopia and hyperopia is not too favorable. With fatigue the eye for both adults and children and neurotic states glasses are used for half an hour in an environment conducive to rest. The principle of operation points-simulators is that if you look through the opaque lens with a hexagonally located small diameter holes, then through the central optical zone of the eye onto the retina the light falls almost exclusively on the subject under consideration, the effect of causing a sharp increase in the depth of focus and resolution. As a result, the eye sees a clearer picture. It turns out that when a person suffering from myopia or hyperopia, is considering an object through the opening points on the retina focuses cloven, but clear and not blurred (as without the glasses) image. The optical system of the eye picks up this discomfort and sends impulses to the brain. As a result of ciliary muscles change the curvature of the eye lens, so that of the ghost to get one clear. These glasses – great trainers for the eye muscles and their effect does not give the eye muscles atrophy, slowing the loss of elasticity of the lens and normalizes the exchange substances in the tissues of the eye, thus preventing cataracts and other eye diseases. That is why such corrective glasses recommended as people with visual impairments, and normally seeing people whose occupation is associated with intense visual load.
