Contact lenses are soft, thin and comfortable, and can easily change the color of the eyes, so they are very popular among young people. However, long-term wearers still experience eye discomfort. What is going on?
Contact lenses need to be used close to the eyeballs, which will hinder the oxygen supply to a certain extent and easily cause discomfort when worn for a long time. Hypoxia in the eyes will cause symptoms such as hyperemia, dryness, and blurred vision. Therefore, contact lenses with lower oxygen permeability cannot meet the needs of eye metabolism. Choose contact lenses with low water content to avoid dryness caused by water evaporation. It can also alleviate the uncomfortable feeling caused by corneal hypoxia.
Contact lens wearers should measure the eye data in detail at the beginning of fitting. If the base curve, diameter, and other parameters do not match the eyeball, the corneal tissue will be rubbed repeatedly during wearing, which will lead to conjunctivitis, corneal ulcers, and other ophthalmic diseases. To prevent the occurrence of inappropriate fitting problems, the editor recommends that you perform an eye examination before wearing contact lenses and review them regularly.
If the contact lens is not cleaned in place, protein, lipid, and other precipitated substances remain on the lens, which easily breeds bacteria, affects the lens's oxygen permeability, and wears the corneal epithelial tissue, and causes discomfort. When operating the lens, you must carefully clean and disinfect your hands. If you have the habit of makeup, you must pay more attention to wearing glasses before makeup and removing them before removing makeup to prevent lens contamination from causing corneal inflammation.
Once you feel uncomfortable wearing contact lenses, you must stop using them immediately and look for the cause. If the symptoms are severe, you should go to the eye examination to confirm the diagnosis as soon as possible to prevent the problem from getting worse and causing other eye problems.
