Hello Tuyen

Welcome to the forum.

OK, since you posted under Acuvue Oasis 1-2 week lenses I assume that is what you are wearing. These are made of silicone hydrogel (senofilcon A) with highish oxygen permeability (Dk 103).

While you shouldn't sleep in lenses without the agreement of your doctor, one night and especially with a lens as breathable as this one, you should have absolutely no problems. The problem with sleeping with lenses, in is that the eye may be starved of oxygen when your eyelids are closed and problems can occur if you do this long term against the doctor's advice.

If your eyes are uncomfortable, just give them a rest without the lenses for say 12 hours and you will be fine.
