A Healthy Alternative
Clear, healthy vision
Sharp, clear vision — any time of the day or night. You can wear NIGHT & DAY™ contact lenses continuously for up to 30 nights and days. NIGHT & DAY allows six times more oxygen to your eyes than the leading soft contact lenses.

The importance of oxygen
Red eyes can be a sign that the eyes are not receiving enough oxygen. Insufficient oxygen also compromises normal eye function and causes uncomfortable lens wear. Patients typically don't experience red eyes with NIGHT & DAY, which are made of a highly oxygen transmissible material. So sufficient oxygen reaches the eye, even during sleep.

If you're considering surgery
NIGHT & DAY lenses are a good alternative to laser vision surgery for the millions of people who are not good candidates for the procedure or who are averse to it due to its high costs, invasiveness, non-reversibility, and potential complications. NIGHT & DAY lenses offer patients the same benefit of continuous, clear vision. To learn more about the risks of laser surgery, check out these informative sites:
