Side effects of wearing contact lenses

Many women who love beauty like to wear contact lenses. Even if they are not nearsighted, they like to wear colored contact lenses to make their eyes look very beautiful. Some people often wear contact lenses and find that their eyes will have tears, stinging, redness and swelling, etc. This makes people very scared, and they rush to the hospital for examination. They find that these are all caused by frequent wearing of contact lenses. Let's learn about the side effects of wearing contact lenses.

1. 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.

Expert advice: Avoid sleeping with it on. The cornea of ​​the eye is a very special organ. It has no blood vessels and breathes with the help of air and surrounding tissues. If you sleep with glasses on, it will affect your eye's breathing, and in serious cases it may cause corneal infection!

2. Cause 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.

Expert advice: The main indicator when choosing contact lenses is water content. If the water content is too high, the lens will absorb moisture from the eye, causing discomfort and drying out. If the water content is too low, the lens will have poor oxygen permeability and your eyes will easily feel dry. This is because oxygen is conducted through the water in the lens. Therefore, the ideal moisture content is between 50% and 60%.

3. Causes optic nerve paralysis

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.

Expert advice: Go to a regular hospital or optician for a detailed examination, choose contact lenses that are suitable for you, and pay attention to your eyes.

Keep hygiene to avoid other eye symptoms. If you experience redness, dryness, pain, fear of light, or poor vision while wearing contact lenses,

If your blood pressure drops, go to the hospital for examination in time.

4. Accelerated corneal aging

If you start wearing soft contact lenses at the age of 20, after 5 years, the number of corneal endothelial cells will be greatly reduced. After the invasion of water, it will easily cause corneal edema. After 10 years, the density of corneal endothelial cells will be equivalent to that of a 60-year-old person. You will not be able to withstand any eye surgery, even if cataracts occur when you are old.
