Are my contact lenses inside out?

Are my contact lenses inside out?

It is often difficult to determine if a disposable soft lens is inside out if the user can't see any markings on the lens or can't judge the edge profile. Here is another way to tell if the lens is correct.

  • Place the lens in your palm.
  • Aim a steady stream of solution on the lens. If the lens folds on itself, then the lens orientation is correct to go on the eye. If the lens does not fold on itself it is inside out.

An alternative method is to hold the lens on the tip of one finger, look at the profile of the lens. If the edges of the lens try to curl back on themselves then the lens is inside out. Finally, once you have inserted the lens, if the lens feels uncomfortable on the eye and will not settle, it could be inside out. It may pay to try it around the other way. Often it settles immediately. You can eventually develop a feel for what is right or wrong when the lens is in your eye.
