Average each long 5 years old, the presbyopic glasses number of degree increases about 50 degrees. In the majority situations, the senior citizen vision improves is the signal which suddenly cataract progresses. When cataract progress, because the crystalline lens nucleus muddy hardening, its optical cheap sunglasses density markup makes the refraction refracting power to increase, enters the intraocular optical fiber the focus point to move ahead presents the nearsightedness to display, thus reduced presbyopia's degree, therefore looks at time the vicinity small character before was clearer. In addition, has the hyperopia ametropia person originally to the part, should pay attention inspects whether to contract diabetes. When the blood sugar elevates, the room water osmotic pressure reduces, the room water permeates in passively the crystalline lens, causes the crystalline lens convexity and the refraction refracting power increases, from this reduced the hyperopia refraction number of degree, but played the transient rise vision role.
Therefore to the vision which appears suddenly changes “good”, with short-range reading when gives up the presbyopia eyeglasses' senior citizen, should consider whether to have ophthalmopathies or whole body disease and so on cataract has affected the eye refraction strength and the sunglasses online adjustment strength. It is known that the ophthalmology department is in Pediatric hospital all outpatient service a outpatient service quantity biggest branch. Usually arrives in the child who the ophthalmology department outpatient service sees a doctor to have 2/5 watches the nearsightedness, as soon as but will arrive has a vacation this proportion to rise to 4/5. “are most, one day will possibly have more than 400 children to look at the eye.”A nurse said like this to reporter. Little while ago,
the Tianjin Women and children Health center Ophthalmology department's staff to the Tianjin urban district, suburban counties 57 kindergarten 10362 5 to 6 year-old child carried on vision screening the result to demonstrate that 6.82% 5 year-old child vision were low, 14.38% 6 year-old chloe sunglasses child vision were low, when had 10.61% 6 year-old child vision with its 5 years old compared drops. Facing these data, the experience which pediatric hospital ophthalmology department Director Yu Gangyi he more than 20 years makes a house call told the reporters, now contracts nearsightedness's child is more and more truly, moreover is approaching the low age development obviously.
According to Director Yu said that besides the hereditary factors, does not rest with the eye health and the endurance with the eye creates the child nearsightedness's primary cause, but “the bad food habit will also facilitate the child nearsightedness” the view is being approved by more and more experts. The modern medicine research proved: The shortsighted pathological change and the eyeball wall's outer layer scierotic's tenacity insufficiency and the crystalline lens change concern raised. d&g sunglasses After suffering from the nearsightedness, wants to restore the vision, either has one's eyes tested and wear glasses the eyeglasses, either chooses the surgery, has no other alternative. Therefore wants to be far away from the nearsightedness, the protection and the prevention are the most important tasks. Some experts believed that the bad food habit is nearsightedness's catalyst, it will rip open the eye prevention nearsightedness's protector
