How to Tell If Contact Lenses Are Right Side Up

If you wear contact lenses, you may inadvertently turn them inside out during cleaning or handling. If you place the lens in your eye while it is inverted, you will likely feel discomfort. You should always check your lenses for damage or stuck-on particles before placing them in your eyes. You can quickly check your contacts to make sure they are right side up while you are inspecting them for other problems.

Instructions

• 1

  Wash and dry your hands well.

• 2

  Remove a contact lens from the case (or from your eye if you suspect it is inside out) for inspection. Hold it at the tip of your finger and notice the appearance of the edges. If the edges go straight up or curl in to make a bowl shape, the lens is right side up. If the edges of the lens flare out, it is inside out.

• 3

  Pinch the lens together to see if it is right side up. If it folds with the edges curled in, it is right side up, according to the Cleveland Clinic. If it flares out and sticks to your fingers, it is inside out.
