What are the consequences of sleeping with contact lenses?

Unless you are using long-wear lenses that have been approved by the relevant authorities. Because the cornea of the human eye is a very special organ with no blood vessels on it, the oxygen needed for metabolism must be provided by the air from the outside world or the surrounding tissues. If you sleep with glasses, it will easily lead to corneal hypoxia, such as corneal edema, stromal streaks or corneal neovascularization, and even corneal infection.

The glasses will not breathe, they will not breathe, and they will have to be removed, but sometimes I forget to take them off, get up and go again, it's okay, if you don't go back, you can't take them off. It's best not to go to bed.

Your eyes don't get rest, and you lose your contact lenses in your sleep.

Contact lenses can not be worn to sleep, which will lead to lack of oxygen in the eyes, especially the contact lenses with poor air permeability and maintenance performance will damage the cornea, so for this reason, you should also wear less contact lenses, not to mention wearing contact lenses when sleeping, the eyes usually need better rest when sleeping, and wearing contact lenses will make the eyes rest poorly, if the nap time is short at noon, you can wear it to sleep, and it is best not to wear it to sleep at night.

1. Breathe with your eyes

Sleep is a relaxing process, during which the human body will slow down breathing, all aspects of the body's functions will also slow down, the eyes are controlled by the brain, although they don't see things, but they will still move with the movement of the brain, oxygen is difficult to enter when the eyes are closed, coupled with the barrier of contact lenses, the cornea of the hypoxic eye is more prone to congestion, redness and swelling than ordinary eyes, bacterial infection, etc., and in serious cases, it will also cause eye ulcers and erosions.

2. Tears secretion

The tears secreted by the surface of the eye will also be absorbed by the contact lenses, which can easily lead to dry eyes the next day and cause great pain, and the lenses as foreign bodies will inevitably rub against the cornea when sleeping, which may cause chronic congestion of the conjunctiva, which will cause conjunctivitis for a long time, and wearing contact lenses while sleeping is equivalent to prolonging the wearing time of contact lenses, and the long-term use of contact lenses will also shorten their lifespan.

3. Contact lens care

There will be proteins, tears, and some secretions on the surface of the eyes, and the contact lenses will inevitably be stained when wearing them, and the human eyes can be constantly washed through tears, so that these things become eye feces and tears are discharged, and the contact lenses will be attached to the dirt and cannot be directly rinsed away, so you have to take off the contact lenses every day, care for and clean the lenses, and then soak them in the care solution, even if you accidentally wear them and sleep for a night, you have to take them off and clean them the next day, and you can use them again after soaking and disinfection.
