Is it harmful to wear contact lenses all night?

Most contact lenses sold in the market are hydrogel contact lenses, which are sometimes worn for a long time, usually not more than 8 hours a day, while silicone hydrogel contact lenses are worn for a little longer.

If you occasionally forget to take it and wear contact lenses to sleep, your first eye will be very uncomfortable. Contact lenses are attached to the eyeball and absorb the tears in our eyes. When you sleep, you always feel something uncomfortable in your eyes, which is easy to cause corneal inflammation, and your eyes will not be ventilated and lubricated by tears, which will easily breed proteins and bacteria. The second person who wears contact lenses overnight is likely to cause red eyes and slight pain in his eyes. When wearing contact lenses again, he will always feel uncomfortable.

It is still recommended not to wear contact lenses overnight. If you wear them for a long time, it is recommended to put some eye lotion on them, so that our eyes will not be easy to dry and uncomfortable.

Good friend, I hope my answer is helpful enough for you.
