Contact lenses have brought convenience to many myopic patients. Many people have taken off the frame glasses and chose to wear contact lenses, but do you know that wearing contact lenses for a long time will bring great harm to our eyes, so what are the specific hazards of wearing contact lenses frequently? What should we pay attention to in summer?

What harm does long-term wear contact lens have?

1. Wearing contact lenses for a long time can cause a lot of 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, so there is a great chance of cataract, but because the retina is too thin, it can not be operated on. So it's better not to wear contact lenses every day.

2. Wear cornea wear cornea, can not accept correction, contact lens wear cornea, may cause corneal epithelial exfoliation or perforation of serious consequences. The concavity of some contact lenses is not consistent with the corneal convexity, irregular wear of the cornea, causing corneal ulcer, resulting in irreversible vision loss, even after treatment, white spots will be left on the cornea.

3. Corneal edema, corneal neovascularization, and ocular hypersensitivity. Contact lenses absorb the proteins, lipids, collagen, etc. in tears, making them deposit on the lens surface, breeding bacteria, corneal edema, corneal neovascularization and allergic reactions.

4. The resistance of the eyes will be reduced. Contact lenses will make the cornea unable to contact the air. The eyes will produce a situation similar to the 'Plateau reaction' of the human body due to lack of oxygen, which will lead to the loss of normal metabolism and resistance.

What should you pay attention to when wearing contact lenses in summer?

1. Wearing contact lenses should avoid the air conditioning cold air blowing directly on the face, which will accelerate the evaporation of water, so that the lenses become dry, resulting in blurred vision.

2. In places with good cooling and ventilation, dust and dust suspended in the air are easy to enter the eyes and adhere to the conjunctiva and contact lens. In this case, do not rub your eyes with your hands. You can take off the contact lenses and clean them.

3. Take off your contact lenses before going swimming in summer. If you have to swim with contact lenses, you can add a pair of swimming goggles, one can avoid the loss of contact lenses, the other can protect your eyes. Contact lenses must be disinfected after each swim. It is recommended to use the daily throwing contact lenses.

4. Don't let sweat fall into your eyes. The sweat is mixed with various bacteria. Once it enters the eyes, it may cause inflammation. If you rub your eyes with your hands, it is more likely to cause some complications, such as conjunctivitis. In case of a large amount of perspiration, wipe off the facial sweat in time.
