So, who is not suitable to wear contact lenses? 1. Primary and secondary school students and adolescents in the growth and development period, the eyeball optic axis has not been shaped, myopia astigmatism degree is not stable, rapid change, and adolescents' self-care ability is poor, do not pay attention to health, for contact lenses strict requirements of cleaning and disinfection and wearing procedures are not easy to grasp and maintain, it is very easy to cause eye infection and corneal injury. Therefore, teenagers should be careful when wearing contact lenses. 2. People with poor working environment, such as all volatile acid and alkali compounds, oil smoke and dust in the workplace. The environment is not good, foreign bodies are easy to enter the eyes, causing eye discomfort, and easily causing eye inflammation.

People with allergies who wear contact lenses are prone to inflammation, such as itchy eyes, redness and swelling. If these diseases are not treated in time, vision may be endangered. 4. When people with fever and cold have a fever and cold, the local resistance of the eyes will decrease, the secretion of tears will decrease, the metabolism of the cornea will not be good, and then the vision will be affected. 5. People with eye diseases such as keratitis, conjunctivitis, glaucoma, dry eye and trachoma are not suitable for wearing contact lenses. 6. People who ride long distance bicycles and the air accelerates convection, which will reduce the water content of soft contact lenses, make the lenses dry and hard gradually, damage the cornea, cause eye pain or bacterial infection. 7.
