This happens when the adhesive of the lash detaches or loosens and eyelashes cannot keep their position properly. This allows the eyelash to recede into the eye (making it appear shorter) or retract into the eye completely. This can affect the counterweight of the eye so the sleep eyes will not function properly. Eyelash retraction can happen to any doll, but usually older dolls have a greater risk. This generally starts to appear in only one eye, though it can happen bilaterally. Pressure on the eyelashes from standard use should not cause retraction.
