Are cosmetic contact lenses harmful to the eyes?

Cosmetic contact lenses are harmful to the eyes because they block the contact between the cornea and the air, causing problems with corneal metabolism and thus eye diseases. If you buy contact lenses of a bad brand, there is a possibility of corneal staining, causing irreversible damage.

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.

If contact lenses are kept attached to the eyeball for a long time, they will paralyze the nerve endings and cause decreased corneal sensation. Many patients are unaware that they have ulcerative keratitis.

Cosmetic contact lenses prevent the cornea from coming into contact with air, and the eyes will experience a condition similar to the human body's "altitude sickness" due to lack of oxygen, resulting in abnormal metabolism and reduced resistance of the eyes.
