When you are older, most people have bad eyes. Recently, a new study published in the journal Visual Science shows that only 16% of the elderly have normal vision. Poor eyesight is an important reason for a series of life problems such as falling down and not going out. However, most elderly people do not care about the problem of glare, and some misunderstandings with the eyes and glasses make the eyes of the elderly more and more flowers.
Presbyopia is caused by the aging and deterioration of the structure and function of the eyeball, but the poor vision after age is not necessarily presbyopia. Before the reading glasses, go to the hospital to do a comprehensive examination of the eyes, including farsightedness, myopia, intraocular pressure and fundus examination. After removing cataracts, glaucoma and some fundus diseases, the optometry can be determined. Try to optometry and optional lenses in hospital ophthalmology or regular optical shops. After the selection, try to wear for about half an hour, and then mold them without discomfort. Some old people are far from being close to each other. This requires two pairs of glasses. You can also use a multi-focus gradient lens with increasing diopter from top to bottom. The top is suitable for viewing far, and the bottom is suitable for viewing. More convenient.
Change the reading glasses three years. As the age increases, the level of presbyopia will also deepen. Once the reading glasses are not suitable, they must be replaced in time, otherwise it will accelerate the eyes. It is recommended to optometry every three years. If the lens of the reading glasses is scratched or aged, it will cause the amount of light to drop, affecting the image quality of the lens, and also replace it in time.
You cannot use a magnifying glass instead of reading glasses. When some old people read newspapers and read newspapers, they like to hold a magnifying glass instead of reading glasses in their hands. Although they can see clearly, they are actually "indulging" their own eyes. If the magnifying glass is folded into the reading glasses, it is equivalent to 1000-2000 degrees. If the magnifying glass is used for a long time, the visual condition will become worse and worse. It is difficult to match the appropriate reading glasses after getting used to it.
In the daily life of the elderly, they should eat more green vegetables and fruits, which will help the regeneration of the important protein in the retina, rhodopsin. Always use a clean hand to gently rub your eyes. When you massage, bend your index finger from the inner eye to the outer corner of the eye, then from the outer corner of the eye to the inner corner of the eye. Press the temple with your forefinger several times, do it again in the morning and evening. It can not only delay the presbyopia, but also prevent the occurrence of chronic eye diseases.
