Disposable lenses seem even better.
Wear them for weeks, then throw them away. That should reduce the number of eye problems. Not really, say ophthalmologists at UT Southwestern Medical Center at Dallas. Anyone who wears contact lenses of any kind for extended periods, especially overnight, is at an increased risk for eye problems. This is because the eyes still get less oxygen, and there's more chance for tiny abrasions on the surface of the eye that allow bacteria to grow there.
