Contact lenses, also called contact lenses, are lenses that are worn on the cornea of ​​the eye to correct vision or protect the eyes. More and more people are wearing contact lenses. Some myopic people wear them for the convenience of daily life, while others wear them for beauty. However, do you know that improper wearing of contact lenses and some incorrect habits will not only fail to make your eyes bright, but will harm your windows to the soul. Do you know the dangers of wearing contact lenses?

The dangers of wearing contact lenses:

Reduced 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!

The hazards of wearing contact lenses 2:

Causes 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%.

The three dangers of wearing contact lenses:

Causes 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.

Experts suggest: When using contact lenses, components in human tears, secretions, impurities or foreign matter in the external environment will inevitably adhere to the lenses to form deposits. Even if you follow a strict care and cleaning process, there will still be invisible deposits remaining on the lens that cannot be removed. It is recommended to use monthly disposable contact lenses or replacement contact lenses with a shorter cycle than monthly disposable lenses.

Eyes are the windows to our soul. Wearing contact lenses for a long time may cause keratitis. If contact lenses are not handled properly, they may easily cause eye allergies. If contact lenses fall off due to falls or collisions, it may bring some inconvenience to your life. Therefore, contact lenses are very harmful and are not recommended for you.
