Can I sleep in my contact lenses?
Unless you are wearing contact lenses specifically designed to be slept in then no you shouldn't be sleeping in your lenses. When you're wearing contact lenses they restrict the amount of oxygen getting to the cornea and with your eyes closed this supply is further constricted. Too little oxygen getting to the cornea can be dangerous and result in swelling, blurred vision and in the longer term, damage to the cornea. If you have accidentally slept in your lenses, drip some saline solution in to the eyes to moisten the lenses and then remove. They should not be reinserted that day. If you have fallen asleep in your lenses and are concerned about the effects, please feel free to contact us.
