2.
long deals with the processes on your computer, you should eat more
fresh vegetables and fruits, while increasing dietary intake of vitamins
a, b, c, e to prevent corneal drying, dry eyes, decreased vision, it is

of the cells. The main function of vitamin e is: lowering cholesterol, clear the body of waste, prevention of cataracts. Nuts,
and peanuts contain large amounts of vitamin e. Vitamin B1 nutritional

Generally involves a myopic check following two ways:
A self check:
Acuity chart self-examination vision. E is in the eyes of the eye chart to identify the targets, called a Visual target. Depending on the subject-a total of 12 lines, level by level to gradually narrow from top to bottom. Are marked with the numbers on the left side of each row, depending on the subject, see all the e-word in this field. There
are logarithmic Visual acuity chart, also known as 5-point scale, a
logarithmic Visual acuity chart the following table e as a Visual
target, consisting of 14 lines. Everyone can see 11. line e as the standard Visual acuity, which is recorded as a 5 or 1. the best visual acuity (5.3). On young children, under 5.2 (1.5) is not normal; Vision 5.1 (1.2), which is the hidden sexual myopia; 5
(1) for critical myopia, features sexually explicit short-sightedness
started 4.9 (0.8) for sexual function, sexual axis of myopia and myopia;
4.8 (0.6) ~ 4.6 (0.4) for mixed gender myopia (OS sexual and sexual regulation of myopia time there); vision below 4 (0.1) for myopia.
As
a 5-point scale, 3 indexes, which you can see only a few fingers on the
front 2 manual, see only a hand shake and see how many fingers; 1 perception of light, only light and do not see anything; 0 there is no perception of light, who is totally blind.
When checking on the nose with cardboard or similar objects, which covers one eye while checking other eyes. Ca"sdwrx33xg"
