Avoid
"glued", note frequency and full flashes, acting on their own, often
blinking eye exposure to air, it may be reduced to prevent tear
evaporation.
Air
conditioner not blowing too long time, prevent air blowing on the seat,
and installed in addition to the headquarters of the tea to increase
humidity around.
Eat all kinds of fruits, especially citrus fruits, should eat more green vegetables, whole grains, fish and eggs. Plenty of fluids also help alleviate dry eyes.
Involved vertically on the body, do not tilt the Flash head and carefully check it says that my vision. Discovery is to figure out the order from top to bottom.
First pointed to the line 0.1 Visual target identification after the test concluded that gap.
Detection by rows and thenFake Oakleys , until I can clear up, depending on the orientation of the gap. Then the digits to the left of this line is measured in the eyes. If you measured your eyes is very poor, even the Visual target of 0.1 is not clear, you can shorten the distance for testing. Slowly approaching the table view the ESA under test, until we can see a gap of 0.1 line e direction so far. Follow the actual tests distance vision in 4 m: 0,08; Visual acuity 0.06 at 3 m, 2 m Visual acuity of 0.04; Visual acuity 0,02 per 1 m (with a standard eye chart, for example, 5 meters). Far Visual acuity with scrutiny at the same time, for the verification of near vision. Because the light emitted so far and near are different objects. Light that distant objects are parallel and the intensity of the nearby objects are loose. Two
different light entering an eye form at different locations, so far
good eyesight eye sight eyes sight is not necessarily better. Better near Visual acuity in the eye, his gaze far away is not necessarily good, so far vision. Usually as a criterion to distinguish between a real vision of up to 5 meters distance.
Check out the short-sightedness, I want to get closer to the eye chart. Far Visual acuity chart from 3 m 30 cm can be measured in the vicinity of the eye sight. Terms
and conditions of the appropriate lighting, distance 30 cm. detection
methods and checkpoints and check for the eye is about the same. If you don't see the 5 line at 30 cm depending on the object, that is, that the Hyperopia or visually.
1. the frequency of the flashes of the habit. Dry eye syndrome is a type of stress disorders, problems in the eyes of the watching to see in one direction for a long time. Adequate rest is the best way to prevent eye fatigue, avoid continuous operation.
1.
Proper glasses is very important for men over 40, double focus lens is
preferred, or while typing, wearing glasses with low levels.
2.
Work posture and distances are also important, try to stay at a
distance of over 60 cm, adapting to the most appropriate posture, which
allows the vision to preserve up to about 30 °, such perspectives can
relax muscles of the neck and eye surface exposed to the air in the area
is reduced to a minimum.
2.
persons engaged in computer operations, you should eat more vegetables
and fruits, while increasing dietary intake of vitamins a, b, c, e to
prevent corneal drying, dry eyes, decreased vision, or even as night
blindness, computer operators, they should eat foods rich in vitamin a,
vitamin c can be effective to prevent the oxidation of the cells. The main role of vitamin e is: lower cholesterol, clearing the rubbish inside the prevention of cataracts. Rich in vitamin e are nuts, and peanuts. Vitamin B1 nutritional nerves, green leafy vegetables contains a lot of vitamin B1. May
be suitable for drinking green tea on a daily basis due to
lipopolysaccharide in tea may improve bodily functions, the function of
tea, there is radiation damage.
Keep good posture. To
maintain the most appropriate posture, binoculars, head or mild down
watching the screen that makes it easy for the neck muscles, and that
area of the eye as soon as possible less exposed to the air.
Adjust the screen distance location. Recommended
distance of 50-70 cm, and the screen should be slightly below the level
of the city face 10-20 cm below 15-20 degrees. Because of the angle and the distance can reduce the demand for refractive errors, reduces the chances of fatigue of the eyes.
If
you have less secretion of tears, eye, easy to dry, it is not
appropriate to use contact lenses into your computer, you'll want to
wear glasses. People who wear contact lenses to your computer, it is best to use a high oxygen permeability rate variety.
For men over 40, double focus lens is preferred, or when typing, wearing glasses with low levels.
If
the redness of the eye, burns or foreign-body sensation, eyelids heavy,
fuzzy, or even eye swelling or headache, still not significantly
improved after the break, then you need to be hospitalized."sdwrx33xg"
