The dangers of contact lenses

Contact lenses now have a large number of users, and nowadays contact lenses have been divided into two types. One is cosmetic contact lenses, which are contact lenses used by people who are not nearsighted and have the effect of visually magnifying the eyes. The other is contact lenses for myopia, which are generally colorless. But no matter what kind of contact lenses you wear for a long time, they will be harmful. Did you know that?

Because contact lenses need to be attached to the eyeball, they will cause some damage to the eyeball. If you do not pay attention to eye hygiene in normal times, the harm of contact lenses will be further increased. What are the specific hazards of contact lenses? You can read the analysis in this article:

The first hazard of wearing contact lenses: decreased eye resistance

Contact lenses prevent the cornea from coming into contact with air, and the eyes will suffer from a lack of oxygen, which is similar to the human body's "altitude sickness", making it impossible to metabolize normally and reducing resistance.

The second harm of wearing contact lenses: causing visual fatigue and dry eyes

Wearing contact lenses for a long time can easily cause visual fatigue and even dry eyes. It causes eye soreness and itching, foreign body sensation, excessive eye mucus, dryness, burning eyes and blurred vision.

The third hazard of wearing contact lenses: causing eye allergies

Contact lenses absorb proteins, lipids, collagen, etc. in tears, causing them to deposit on the surface of the lens, breeding bacteria, and causing corneal edema, corneal neovascularization and allergic reactions.

The fourth hazard of wearing contact lenses: corneal abrasion and inability to receive correction

Contact lenses can abrade the cornea, potentially causing serious consequences such as corneal epithelial detachment or perforation. The concavity of some contact lenses does not match the convexity of the cornea, which causes irregular wear of the cornea and causes corneal ulcers, resulting in irreversible vision loss. Even after treatment, white spots will be left on the cornea.

The dangers of wearing contact lenses are more than those mentioned above, but this article will only introduce them to you here. It is only recommended that women who are not nearsighted should wear contact lenses less often, and it is best not to wear them at all. It is also recommended that friends who wear contact lenses must take good care of their glasses and eyes when using them to avoid causing damage to their eyeballs.
