Cornea is really "delicate". Frequent rubbing of eyes, wearing inappropriate contact lenses, using inappropriate eyedrops, unreasonable diet, and light pollution will make him "lose his temper". In the long run, symptoms such as keratitis, amblyopia and cataract will appear, even leading to blindness.
The nutritional requirements of cornea are comprehensive. Eye drops, delicious food and daily care are indispensable. Different nutrition can bring different health improvements to corneas, so that health problems can be alleviated at the first time and hidden health problems can be eliminated in the initial state.
In many people's opinion, the reason why the cornea is injured is simply that the time spent watching computer and TV is too long. In fact, the act of injuring the cornea is far more than that. A simple eye rubbing action or the use of eye lotion that has been opened for more than 45 days are all the "murderers" who hurt the cornea!
The cornea works like this
The cornea is very thin, only 0.5mm thick, but it contains five layers of tissue, of which the epithelial layer is the most important protective tissue. Its cells are constantly renewed and closely arranged. Always protect your eyes from outside bacteria.
The cornea is transparent without blood vessels. If you can ensure that it is moist and not dry, the visual clarity and stereoscopic sense will be very good. It is just like the lens of a camera, which directly affects the quality of the image people receive.
In addition, the cornea can also prevent the eyes from being "troubled" by pain. Because there are very sensitive nerve endings in its "body", the eyelids will automatically close once a foreign body contacts or is stimulated by sudden strong light. In the shortest possible time, the eyes can be fully protected. This protective barrier minimizes the appearance of eye "trauma".
The eyes are really "hurt"
One of your carelessness is likely to cause damage to the cornea and bring about considerable health risks to the eyelids.
Corneal killer: light pollution
Injury level: ★★★★
When the eyes stare at the computer and TV screen for a long time, the light beam will focus on the retina through the lens of the eye, which will make the eyes extremely tired.
At the same time, because the blink frequency is reduced, the evaporation frequency of tear film used to maintain the wetness of the eye surface is accelerated, which can no longer moisturize the cornea. The eyes will often feel uncomfortable.
The reflective light of mirror buildings, granite and marble is very bright, and the retinal cells of the eyes are suddenly stimulated. Unable to adapt and cause discomfort. Long term exposure to strong sunlight can also cause corneal diseases, such as those of the elderly.
Corneal killer: wear contact lenses for a long time
Injury level: ★★★
If contact lenses are cut off for a long time, especially those with low oxygen permeability, the cornea is prone to edema, which affects the cornea metabolism and light transmittance, causing blurred vision.
Corneal killer: incorrect eyedrops
Injury level: ★★★
Many people, no matter what happens to their eyes, pick up a bottle of eyedrops to use, thinking that each kind of eyedrops will contain anti-inflammatory and soothing substances. But in this way, not only may the real eye problem not be solved, but it will lead to new problems and make the cornea unbearable. For a long time, it will certainly strike.
Corneal killer: bad habit
Injury level: ★★★
Wearing contact lenses, sleep when sleepy; Rub your eyes when they are uncomfortable or itchy; Outside, the sun is in the sky, but sunglasses are "on holiday" at home; While sleeping, the computer and TV are still working tirelessly. Many people are not unfamiliar with this series of habits, but they are the main culprits of cornea damage.
If you sleep with contact lenses, the permeability of the cornea will be affected, and the dryness will become more serious; Rubbing your eyes with your hands often can easily bring bacteria into your eyes and cause inflammation; Regular exposure to sunlight, computer and TV radiation will lead to premature aging of the cornea, which requires nutritional supplies to maintain "normal work".
Corneal "nourishment" is comprehensive
Ophthalmologists tell us that we should protect our eyes as well as our skin, protect their moisture, and replenish the needed nutrients for the cornea at any time.
Corneal nutrition comes from the inside of the eyeball, such as amino acids and glucose. In addition, oxygen is an important substance to maintain corneal cell metabolism and corneal health, and 80% of the oxygen in the cornea is obtained by dissolving the oxygen in the atmosphere. Therefore, it is essential to keep the eyes moist for corneal cell health.
Moisture - eye drops
Eye moisturizers are emerging one after another, but for resisting light pollution, eye drops containing vitamin B and panthenol are the best choice, because these two ingredients can maintain cornea metabolism, reduce intraocular pressure, regulate vision, and relieve eye muscle fatigue.
If the eyedrops contain a unique mint cooling formula, they can "refresh" the eyes and spirit in the afternoon of excessive fatigue, and also promote the metabolism of our eyes and relieve fatigue
Wearing contact lenses for a long time will definitely cause dry eyes. Is there any good solution? Choose eyedrops for contact lenses. It is different from traditional eyedrops -- if you wear contact lens drops, the traditional eyedrops will block the air holes of the contact lenses, and the drug residues will cause the lenses to become hard and wear the cornea.
The preservative may irritate sensitive eyes, so the eye lotion decomposed by the preservative in the presence of light is a must, and its eye protection effect is incomparable. Do not let the mouth of the bottle touch the eyelashes when dripping the eye lotion, so as not to pollute the product. The product shall be used up within 45 days after opening.
Oxygen -- special contact lenses
Because there are no blood vessels in the cornea, it is necessary to breathe fresh air to maintain health. For this reason, contact lenses need to have good oxygen permeability.
There is a kind of contact lens on the market that uses innovative silicon hydrogel material. Its oxygen permeability is 5 times that of ordinary hydrogel lens, which can meet the daily demand of cornea for oxygen, care for cornea health, effectively solve the problems of fatigue, dryness, congestion, etc. that often occur in the eyes, and bring all-weather comfort to the eyes.
Smart consumers should also choose and match the nursing liquid that can not only moisturize the eyes for a long time, but also protect the health of the eyes. For example, the eye care liquid containing the moisturizing ingredient HPMC has high compatibility with corneal cells on the basis of its strong bactericidal ability. It does not damage corneal cells, so that eye cells can maintain a healthy state.
Only contact lenses and nursing liquid are both healthy choices, can we make eyes more comfortable and comfortable on the basis of improving vision.
Food -- all kinds of delicious food
Did you know that it is necessary to extract sufficient nutrition from food in order to improve the brightness of cornea and the sensitivity of reaction to things.
Vitamin A can repair damaged cornea cells and protect eye health. To this end, please eat animal liver, fruit, vegetables and carrots and other foods rich in vitamins.
In addition, another element that protects the cornea is vitamin B. It is an antioxidant of the eye itself, which can promote metabolism and protect corneal tissue. In addition, OMEGA-3 is also a good ingredient to protect the cornea. It is high in deep-sea fish and bean products, which can increase the secretion of tears, thus nourishing the eyes.
Self "Massage" -- Reduce Corneal Pressure
Excessive fatigue will make the cornea bear too much pressure, and the ability to perceive things will be greatly reduced. Of course, you don't need to panic too much. As long as you use 10 minutes of self massage on your eyes every morning and afternoon, you can lower the intraocular pressure, increase the permeability of your cornea, and let you "see higher and look farther".
The correct method is: start from the eyebrow bone at the upper end of the eyebrows, and slowly slide the nails from the center of the eyebrows to the top of both sides. In this process, stimulate the eyes. The manipulation should not be too heavy, as long as it can stimulate the eyes. If the force is too heavy, it will cause excessive pressure on the eyes and reduce vision. Remember, persistence is most important.
Exercise -- decontamination of cornea
If the eyes often look at the same place, the microorganisms on the surface are easy to stay. If they are not cleaned in time, corneal inflammation is easy to occur. This situation can usually be solved by blinking your eyes frequently! You might as well leave the computer every hour, stand in front of the window and blink. After 5 minutes, all the microorganisms attached to the corneal surface can be removed, and the tear film can be evenly distributed to all corners of the eyes to moisturize the eyes.
Cornea loves her most
Although the cornea is very fragile, it loves some of us very much, because these people have good living habits, which can improve the health of the cornea day by day.
"Fragile" OL
Tears are a woman's patent. When encountering setbacks, she knows how to release herself with tears. It also protects the health of the cornea and keeps it moist. There will be no dryness.
People who love cleaning up
The cornea loves women who often clean their eyelids, because once the gland is blocked, the secretion of oil will be affected, and then the effective evaporation rate of water will be affected. Dry eyes and astringent eyes will appear. If you are a text worker who often uses your eyes, and if you often feel sore or itchy in your eyes, please clean your eyelids regularly twice a week. The correct way to clean the eyelids is simple. Wipe the edges of the eyelids with a wet cotton swab.
"Very industrious" people
The cornea also needs regular physical examination. Go to a regular hospital every six months to check the eye health. It is very beneficial to maintain the best state of the cornea and control the eye disease at the initial stage. How can the cornea not like such a hardworking person?
