Is it true that there are contacts that you can sleep with and don't need to take off for a long time?

Yes it is true that there are "extended wear" contacts that are FDA approved for overnight wear and longer periods of time. There are many risks involved that you need to be aware of :
"Extended wear is different from daily wear because extended wear puts more stress on the eye, extended wear requires special precautions. First, extended wear requires healthy eyes that can tolerate the added stress. In addition, overnight wear requires the use of special extended wear lenses that are available in both soft and rigid gas permeable (RGP) materia1s. Fortunately, serious eye infection is a rare problem for contact lens wearers. But people who wear their contact lenses overnight have a higher risk of developing infection and other problems than people who take their lenses out every night. Finally, because there is higher risk, extended wear means more frequent check-ups are needed from your eyecare professional. As a result, extended wear lenses can cost more than daily wear. "

There are higher risks of eye infection and getting giant papillary conjunctivitis (eyelid develops an allergic-type reaction to deposits on the lens)

To avoid these complications :
-Keep to the wear schedule your eyecare professional has given you.
-If you use disposable or frequent replacement lenses, replace the lenses as planned.
-Any time you remove and re-use a lens you've worn, clean, rinse and disinfect the lens carefully before putting it back in your eye.
-Periodically give your eyes a break and sleep without your contact lenses. (Follow carefully the schedule prescribe by your eye care professional. Usually, one night "off" per week.)
-Keep all scheduled follow-up appointments with your eyecare professional, even if some of the visits aren't covered by your health plan.
