No, a thin, but strong, membrane, called the conjunctiva, lines the inside of your eyelids and curls back on itself to cover the white part of the eye. Lenses cannot pass through it. However, your contact lenses may slide under your eyelids or become displaced. If this occurs, try looking in the direction of the lens to get it to move back to the correct position. If you wear soft contact lenses, they will tend to center automatically on the cornea. If you wear rigid gas permeable lenses, you may need to manipulate a displaced lens through the eyelid.
