Introduction to the pros and cons of contact lenses

We all know that many young people have myopia problems, mainly because they do not use their eyes correctly, so we recommend that young people do not face computers for a long time to avoid vision loss. However, many young people nowadays do not like to wear glasses because they will affect the beauty of their faces, so many young people choose to wear contact lenses to enhance their vision.

Wearing contact lenses (contact lenses) will make your eyes feel a little uncomfortable (in the early stages), even soreness and tearing, but you will usually get used to it after a few minutes. Some people may experience temporary conjunctival congestion, decreased corneal sensation, etc. So generally start with a short-term wear, 6-8 hours a day, and take it off at night when you sleep or are not working. As you gradually adapt, you can extend the time appropriately. Some soft lenses can be worn continuously for 4-7 days or longer.

Doctors have 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 objects placed on the cornea. Every time you blink your eyes, the contact lenses will produce a certain amount of friction with the surface of the eyeball. At the same time, they cover the surface of the cornea, making it difficult for the cornea to absorb oxygen directly from the air. Therefore, long-term or continuous wearing of contact lenses will keep the cornea in a state of continuous hypoxia, causing corneal epithelial edema and erosion. If bacteria or viruses are present, it may lead to keratitis and even corneal ulcers.

It is best for women to let their contact lenses "rest" during menstruation and pregnancy. Because before and during menstruation, intraocular pressure will be higher than usual, and the area around the eyeball will be more prone to congestion, especially for women with dysmenorrhea. Wearing contact lenses at this time will have adverse effects on the eyeball. During pregnancy, hormone secretion changes, which causes changes in the water content in the body. The eyelids become a little swollen and the cornea becomes thicker. Especially in the last three months of pregnancy, the cornea contains more water and becomes thicker, which is more obvious and will not match the contact lenses selected normally, thus causing eye discomfort. Pregnant women with edema of pregnancy should especially avoid wearing contact lenses.

Through this article's introduction to the pros and cons of contact lenses, I hope you can pay more attention to them in your life. Although contact lenses may look more beautiful, wearing them frequently may cause increased pressure on our eyes, especially for women during menstruation, which may cause eye inflammation.
