As many types of contact lens care systems are becoming harder to find, wearers are turning to All-in-One Multipurpose Solutions. "No rub" is usually written prominently on the bottle. But when it comes to cleaning your contacts thoroughly, there's still no substitute for rubbing.

No matter what the bottle says, here's what to do: Take your lens, add a couple of drops of the solution, and rub the surface for a few seconds — either between thumb and forefinger, or by placing on your palm and rubbing with forefinger. Be sure to rub both sides before rinsing well with your multipurpose solution or saline.
