Common contact lens hotspots

Nowadays, more and more girls are wearing contact lenses, but these girls may not know that wearing contact lenses incorrectly and some incorrect habits can harm their eyes. Q: Can I sleep with contact lenses? A: Of course not. And absolutely not. Except for some long-wearing lenses approved by the national testing department, other invisible products cannot be worn overnight, nor can they be worn to sleep. Human eyes are very sensitive and need to breathe, and if you wear contact lenses to sleep or even overnight, it can greatly hinder your breathing. Without the supply of oxygen, the eyes will be uncomfortable, and in severe cases, it will lead to corneal hypoxia or corneal edema, and even lead to corneal infection. Q: Why is the prescription of contact lenses different from that of eyeglasses? Answer: Eyeglasses are placed in front of the eye, while contact lenses are directly attached to the front of the cornea, there is no vertex distance effect of glasses, and according to a certain optical principle, the power of contact lenses is slightly lower than that of glasses in people who are nearsighted, and the opposite is true for people who are farsighted. Q: Is it better to have thinner contact lenses? A: Not absolutely. Thin contact lenses increase oxygen permeability and improve comfort, but they are prone to lens drying, dehydration, corneal dryness, corneal staining, and lens breakage. Q: Can I swim while wearing contact lenses? A: No, you cannot. Because the swimming pool contains a lot of chemicals and bacteria, it is recommended not to wear it. If necessary, use disposable lenses and swimming goggles. Remove the lenses and discard them after swimming. Q: Can I still use my contact lenses after a scar? Q: What should I do if I wear contact lenses and wear makeup? A: If you need to wear makeup, please wear the lenses before applying makeup, and then remove the makeup. Do not touch the lenses with your fingers that have been stained with makeup, and close your eyes if you need to spray hairspray or other sprays after wearing the lenses. Q: Can I use eye drops while wearing contact lenses? Answer: When wearing contact lenses, you can only use contact lens lotion that is specially used for contact lens wearing, and do not use eye lotion that is not for contact lenses. If you need to apply other eye drops, remove the lenses and use them. Q: Can I still use my contact lenses after a scar? Small scars on the lenses vary in severity, and in severe cases, they may cause irritation to the eyes and damage the surface of the cornea, so you need to go to a branch to replace the lenses. Small scars on the surface of hard contact lenses can be corrected by grinding, but soft contact lenses cannot be corrected.
