Cornea is very important, which is the "protective umbrella" of the eyes and determines the clarity of vision. Once its health has problems, its vision will be weakened. It can be seen that we really need to pay attention to the "feeling" of the cornea at all times, replenish nutrition for it at any time, keep the cornea in the best condition, and help you harvest more beautiful scenery.
1, corneal killer: light pollution
When the eyes stare at the computer and TV screen for a long time, the light beam passes through the lens of the eye and is all concentrated on the retina, which will make the eyes extremely tired. At the same time, due to the decrease of blink frequency, the evaporation frequency of tear film used to maintain the wettability of eyeball surface is accelerated, which no longer provides moisture for cornea, and eyes often feel uncomfortable. The reflected light of mirror architecture, granite and marble is very bright, which makes the retinal cells of the eyes suddenly stimulated, and the eyes can't adapt and feel uncomfortable. Long-term exposure to strong sunlight can also cause corneal lesions, such as corneal lesions in the elderly.
2, corneal killer: wearing contact lenses for a long time
Wearing contact lenses for a long time, especially contact lenses with low oxygen permeability, is prone to corneal edema, affecting corneal metabolism and light transmittance, resulting in blurred vision.
3, corneal killer: incorrect eye drops
Many people, no matter what happens to their eyes, pick up a bottle of eye drops and use it, thinking that every drop of eye drops will contain anti-inflammatory and soothing substances, but they have not chosen the right product. But in this way, perhaps the real eye problem has not been solved, but new problems have emerged one after another. The cornea is under overwhelming pressure and will definitely go on strike for a long time.
Method for protect cornea and supplementing eye nutrition
1, corneal nutrition: moisture-eye drops for choice.
Eye drops emerge one after another, but in order to resist light pollution, eye drops containing vitamin B6 and dexpanthenol are the best choice, because these two components can maintain corneal metabolism, reduce intraocular pressure, adjust vision and relieve eye muscle fatigue. If the eye drops contain a unique mint cold formula, it can make the eyes and our spirit get a "refreshing" effect in the afternoon of excessive fatigue, and at the same time, it can 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? Choosing special eye drops for contact lenses is different from traditional eye drops. If you wear contact lenses, traditional eye drops will block the pores of contact lenses, and the lenses will harden due to drug residues, thus wearing the cornea. The new eye drops for contact lenses can be used safely without taking off the contact lenses.
Preservatives may irritate sensitive eyes, so eye cream that can be decomposed by preservatives is an essential choice, and its eye protection effect is unparalleled. When dropping eye drops, don't let the bottle mouth touch the eyelashes to avoid polluting the product. After the product is opened, it should be used up within 45 days to ensure the best effect.
2. Corneal nutrients: oxygen-containing contact lenses
Because the cornea has no blood vessels, it needs to breathe fresh air to keep healthy. So contact lenses need to have good oxygen permeability.
The latest contact lenses are made of innovative silica gel hydrogel, and their oxygen permeability is five times that of ordinary hydrogel lenses, which can meet the daily demand for oxygen of cornea, care for corneal health, effectively solve the problems of eye fatigue, dryness and congestion, give eyes all-weather comfort, and fully meet the needs of daytime rest and long-term wear.
Smart consumers had better choose a care solution that can moisturize and protect eye health for a long time, such as HPMC, which contains moisturizing ingredients, has high compatibility with corneal cells on the basis of super bactericidal ability, does not damage corneal cells, and keeps eye cells in a healthy state. When contact lenses and nursing solutions are healthy choices, we can make our eyes more comfortable and more comfortable on the basis of improving our eyesight.
3, corneal nutrients: food-all kinds of delicious eyes.
Do you know that it is necessary to extract enough nutrients from food in order to improve the brightness of cornea and sensitivity to things?
First of all, vitamin A can repair damaged corneal cells and protect eye health. To this end, please eat more foods rich in vitamins such as animal liver, fruits, vegetables and carrots; In addition, another element that protects cornea is vitamin B 12, which itself is an antioxidant for eyes, and can promote metabolism and protect corneal tissue. In addition, OMEGA-3 is also a good component to protect the cornea. Deep-sea fish, tofu and other bean products are high in content, which can increase the secretion of tears and thus moisturize the eyes!
Use up the eye drops as soon as possible after opening them.
Eye drops are not commonly used, but they must be used up as soon as possible after opening. The eyes are easily infected, so you must pay attention to hygiene when using eye drops. Many people have done some harm to their eyes because of improper use of eye drops. Bian Xiao specially arranged some ways to use eye drops, hoping that everyone can choose the right eye drops correctly, really protect their eyes and protect the windows of our hearts.
1, it is best to wash your hands and dry them before taking the medicine to avoid secondary infection. Gently wipe the eye secretions with clean gauze piece or cotton swab, and dry the tears.
2. Look at the drug name and expiration date before taking the medicine to prevent misuse.
3. When dropping eye drops, the patient can sit or lie on his back, with his head tilted back and his eyes looking towards the top of his head. Separate the eyelids by hand, drop 1-2 drops into the eyes, gently close your eyes for 2-3 minutes, and press the lacrimal sac (near the corner of the nose) at the same time to fully disperse the liquid medicine, thus obtaining better curative effect.
4. The dropper head should not touch the eyelids or eyelashes, so as to avoid scratching the eyes or causing liquid pollution.
5. When eye ointment and eye drops are used together, use the drops first, and then use the ointment after a while, because the oiliness of the ointment will hinder the absorption of water-based drugs and affect the therapeutic effect of water-based drugs.
6. The dosage of eye drops should be 1-2 drops each time. Excessive dosage will stimulate tears in eyes and bring out liquid medicine, which will affect the curative effect.
7. Don't use it less or stop using it at will.
8. Once the eye drops and ointment are opened, they should be used up within a certain period of time. Don't use it after a long time.
9. Do not use the eye drops when they are abnormally turbid or discolored.
