1. Long term use of contact lenses can cause many eye diseases, such as keratitis, conjunctivitis, etc. 10 years is equivalent to the aging of the retina to 60 years old, and it will become thinner, with a high probability of developing cataracts. However, due to the thin retina, surgery cannot be performed. So it's best not to wear contact lenses every day.

2. Wear and tear of the cornea, which cannot be corrected, and contact lens wear and tear of the cornea may cause serious consequences such as corneal epithelial detachment or perforation. The concavity of some contact lenses does not match the convexity of the cornea, causing irregular wear and tear on the cornea, leading to corneal ulcers and irreversible vision loss. Even after treatment, white spots may still be left on the cornea.

3. Corneal edema and corneal neovascularization reactions can cause eye allergies. Contact lenses absorb proteins, lipids, collagen, and other substances in tears, causing them to deposit on the surface of the lens and breed bacteria, leading to corneal edema, corneal neovascularization, and allergic reactions.

4. The resistance of the eyes decreases, and contact lenses can prevent the cornea from coming into contact with air. The eyes may experience a condition similar to the "altitude sickness" in the human body due to lack of oxygen, resulting in abnormal metabolism and decreased resistance.
