There are usually two reasons for dry eyes: one is that the supply of tears is reduced, and the other is that the evaporation of tears is increased.
The reduction of tears is a characteristic of modern people. Tears are difficult to flow out under tension and decrease at night. Tears also decreased with age. Office automation equipment, the lifestyle of night owls, increasing social pressure and dryness due to the popularity of air conditioners are more and more factors that reduce tears.
The reason for the increase in evaporation is that the number of blinks decreases due to gazing at the pictures of personal computers and game consoles; The oil layer on the tear surface became unstable for some reason.
The oil layer is secreted from the eyelid sebaceous glands located at the edge of the eyelid, but it is often blocked. If you use towels to heat your eyes, you can improve blood circulation and eliminate eye muscle fatigue.
top view dry eye
By adjusting the placement of the computer and the angle of the monitor so that the angle of view between the eyes and the monitor is a top view angle, the evaporation of tears can be reduced and the dryness of the eyes can be effectively alleviated. This overlooking method is also effective for the elderly when reading books, newspapers or watching TV.
eat bananas to prevent dry eyes
The function of banana to protect eyes is first related to its rich potassium content. If the human body takes in too much salt, a large amount of water will remain in the cells, causing redness and swelling of the eyes. The potassium in bananas can help the human body to excrete these excess salts, so that the body can achieve a potassium sodium balance, and alleviate eye discomfort.
Bananas contain a lot of β Carotene. When the human body lacks this substance, the eyes will become painful, dry, dull, and dehydrated. Eating more bananas can not only alleviate these symptoms, but also alleviate eye fatigue to a certain extent and avoid premature aging.
blink to prevent dry eyes
Blinking is equivalent to rest. Normal people blink once every five or six seconds. People who often feel eye interference should blink once every ten seconds or even more. The number of blinks is greatly reduced, and the regulation of blood vessels and nerves is disordered. The cornea, which is usually moistened by eyedrops, becomes dry and congested.
