It is inconvenient to wear glasses all the time. I don't know how invisible they are. Are there any side effects?

Wearing contact lenses (contact lenses) will make the eyes feel uncomfortable (initially), even painful and tearful, and will gradually adapt after a few minutes. Some people will cause temporary conjunctival congestion and corneal hypoesthesia. Therefore, it is usually worn for a short time at first, 6-8 hours a day, and it is taken off when sleeping or not working at night. After gradual adaptation, the time can be appropriately extended. Some soft glasses can be worn continuously for 4-7 days or longer. Pay attention to the following problems when wearing contact lenses.

1. Ask a doctor to check whether there are indications for wearing contact lenses.

2, contact lenses must be suitable, smooth surface, can not be worn off, good transparency, appropriate curvature and so on.

3. Contact lenses must be kept clean to avoid bacterial contamination, stored in special care solution, and then cleaned with cleaning solution before wearing.

4. Wearing contact lenses for the first time should be done under the guidance of a doctor. Wash your hands with soapy water and clean water first, then clean the mirror with cleaning solution, put the lens on your index finger and suck it with a small rubber tube. Be careful not to blink at this time, and then gently stick it on the cornea.

In the first few months of wearing contact lenses, you should often go to the hospital to check your eyes. If you find that your eyes are sore, red and blurred, you should stop wearing glasses immediately. Corneal epithelium healed after treatment, and then continued to wear.

6, suffering from acute conjunctivitis, dacryocystitis, corneal epithelial injury, glaucoma and other eye diseases are prohibited to wear contact lenses.

Health problems caused by contact lenses are increasing. It is estimated that nearly half of the wearers neglect the disinfection and cleaning of contact lenses, which leads to corneal inflammation.

Wear contact lenses, health first.

In medicine, contact lenses are called "contact lenses". Even if the lens is of good quality and high oxygen permeability, it will hinder the eye's demand for oxygen. Therefore, wearing contact lenses should pay attention to hygiene.

Doctors found that many people wear contact lenses for a long time, which is an important factor leading to eye diseases such as bacterial keratitis. After all, contact lenses are foreign bodies placed on the cornea. Every time you blink, the contact lens will rub against the eyeball surface, and at the same time it will cover the cornea surface, making it difficult for the cornea to directly absorb oxygen from the air. Therefore, wearing contact lenses for a long time or continuously will make the cornea in a state of continuous hypoxia, causing corneal epithelial edema and erosion. If bacteria or viruses exist, it may lead to keratitis and even corneal ulcer.

Because contact lenses directly contact the cornea, strict hygiene requirements are required. Although many people know this in theory, it is easy to ignore the cleaning of lenses in daily life, either because of haste or fear of trouble, which leads to bacterial infection in the eyes.

Cosmetics often bring troubles to contact lens wearers. For example, misuse of cosmetics can lead to contact lens deposition, eye inflammation, allergic reactions and infections. When wearing contact lenses, you should wear glasses first and then make up. Do not draw eyeliner into the inner edge of eyelid or beyond the eyelash line of lower eyelid. Don't apply weak foundation on your face, and don't use cream too close to your eyes.

People who wear contact lenses and use computers should blink more to help their eyes moist and take regular rest. It's best to keep working for about an hour, rest for 5 minutes and look at the distance.

Who should not wear contact lenses?

Some people should not wear contact lenses. For example, people suffering from eye diseases such as blepharitis, severe trachoma, conjunctivitis, keratitis, dacryocystitis, dry eye or glaucoma should wait until the inflammation disappears.

At present, there are not a few primary and middle school students wearing contact lenses, but experts point out that contact lenses are not suitable for primary and middle school students. They are in the vigorous period of growth and development, and the visual axis of the eyeball has not yet been finalized. If you wear contact lenses too early or for a long time, it is easy to produce side effects such as corneal hypoxia and physiological and metabolic disorders. If the curvature of the lens does not adapt to the cornea, it will also cause corneal wear, which will lead to corneal ulcer or perforation in severe cases. Therefore, unless there is a special need, primary and secondary school students had better wear frame glasses.

After the age of 40, we should also gradually bid farewell to contact lenses. Because at this time, the human eye tissue will undergo obvious degeneration, and the local resistance of the eyes will decrease, especially the ability of the eyeball to tolerate hypoxia. Therefore, people aged 40 to 60 can wear it for a short time, and it is best not to wear it over 60.

When should contact lenses "rest"

It is best for women to "rest" their contact lenses during menstruation and pregnancy. Because before and during menstruation, the intraocular pressure will be higher than usual, and the eyeball will be more congested, especially for women with dysmenorrhea. If you wear contact lenses at this time, it will have a bad effect on the eyeball. During pregnancy, the secretion of hormones changes, so that the water content in the body also changes, the eyelids are a little swollen, and the cornea thickens, especially in the last three months of pregnancy. Because of more water, the cornea thickens more, which will not match the normal contact lenses, thus causing eye discomfort. Pregnant women with gestational edema should not wear contact lenses in particular.

Don't wear contact lenses when you have a cold. Wear frame glasses instead. Because the surface environment of the eyeball depends on the following factors: whether there are enough tears, whether there is enough oxygen and whether there are other problems in the eye, and contact lenses will change the surface environment of the eyeball. Wearing contact lenses when catching a cold will greatly increase the chances of other eye complications. In addition, cold patients often have a lot of germs on their hands, which can easily enter their eyes during the process of taking and wearing contact lenses. Moreover, many cold medicines, cough medicines or painkillers contain ingredients that inhibit tears. The decrease of lacrimal gland secretion will make contact lenses too dry and reduce transparency, thus affecting vision.

Don't wear contact lenses for long-distance cycling. Because when riding a bicycle for a long journey, the air accelerates convection, which will reduce the moisture of soft contact lenses, the lenses will gradually dry and harden, and the eyes will feel uncomfortable. Over time, hardened lenses can damage the cornea, leading to eye pain or bacterial infection.

No matter how good the quality of contact lenses is, they are all foreign bodies to the eyes, which are imposed by you, so they will definitely have an impact on the eyes, so I suggest you pay attention when using them. In addition, you must pay attention to using your eyes after the operation, otherwise it will easily recur. I hope your eyes are more and more beautiful.
