Are there any dangers of wearing colored contact lenses with a certain degree

Colored contact lenses are a kind of flat contact lenses that can change the color of the eyeballs. Some eyewear brands see that women love colored contact lenses very much, so they launch colored contact lenses with degrees, so that more people can become beautiful. Many people with myopia choose cosmetic contact lenses with degrees to make their eyes more lively. Are there any harms in wearing cosmetic contact lenses with degrees frequently? Here we will tell you the benefits and harms of contact lenses.

1. The benefits of wearing contact lenses

1. More beautiful and convenient

Contact lenses are not obstructed by frames, are weightless, and have no effect on the wearer's appearance. They are very suitable for people who love beauty, especially women. Without the hindrance of glasses frames and the risk of frame lenses breaking, contact lenses also bring greater convenience to athletes.

2. Broader vision

Wearing contact lenses can make your vision clearer and your field of vision wider. When wearing frame glasses, there is a certain distance between the eyes and the lenses, while contact lenses are tightly attached to the surface of the cornea, and there is no distance between the lenses and the eyes, so the size of the image seen is close to the real one.

3. Play a more protective role

Contact lenses have the function of protecting the cornea and can also release drugs slowly. They are clinically used to treat eye diseases such as chemical burns, glaucoma, and keratitis. It can also protect the retina of patients with iris defects, albinism, etc. from excessive ultraviolet radiation.

2. The hazards of wearing contact lenses

1. Reduce the resistance of eyes

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.

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.

3. Cause 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.

4. Corneal abrasion, unable 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 corneal ulcers, resulting in irreversible vision loss. Even after treatment, white spots will be left on the cornea.

5. 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.

6. 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.
