Hello all!  For a few years now I have noticed a flap of skin behind
each of my upper eyelids - attached to the lower eyelid.  It can be
irritating at times, but I have grown used to it.  I was wondering if
it was natural (perhaps due to long term use of contact lenses) or if
it should be removed.  The flap is approx. 1cm in height and reaches
each end of the eyelid.  It feels slightly thicker than the eyelid
itself and I am able to fold it freely with no pain.
Sincerely,
