The doctor warned about the consequences of sleeping in lenses.

Anna Toltaeva, a doctor at the Vision Ophthalmological center, spoke on Wednesday, March 18, about the risks that the habit of sleeping in contact lenses can lead to.

According to the ophthalmologist, lenses that are not designed to sleep in them severely restrict oxygen access to the cornea and disrupt the normal exchange of tears under it. In addition, people do not blink in their sleep, so germs and dirt are easier to retain on the surface.

The doctor noted that after sleeping in lenses, photophobia, dryness, a feeling of sand, redness and a feeling that something is interfering most often occur.

"Sometimes it can cause micro-damage to the epithelium of the eye. Infectious keratitis develops less frequently, and in severe cases, corneal ulcer is possible. Dry eye syndrome may also worsen and vascular sprouting may occur as a reaction to a chronic lack of oxygen," the specialist said in a conversation with Lenta.Ru .

She added that the risk of unpleasant consequences increases if you sleep with lenses on during a cold and after drinking alcohol.
