Contact lenses moves in my eyes, why is this?

2 possibilities: Some movement of contact lenses is normal and desirable. Too much movement causes blurred vision and discomfort. Your eye doctor can evaluate whether the amount of movement is okay or if you need a different contact lens.

Return to: The doctor who fit the contact lenses. A small amount of movement, typically a millimeter or less, is desirable. More movement than this will cause lens dislocation or discomfort. Generally contacts that move too much must fit with a smaller (ie. Tighter) base curve.
