AB  - The  eyelids  play  an  important  role  in  maintaining  ocular  health  and  good  vision.  The  mechanical  action  of  the  eyelids  sweeping  over  the  globe  brings  in  fresh,  lubricating  tears  and  removes  debris.  The  edge  (margin)  of  the  two  upper  eyelids  and  two  lower  eyelids  should  be  symmetric.  The  upper  eyelid  margin  should  rest  at  the  superior  edge  of  the  cornea  or  just  over  the  superior  iris,  so  as  not  to  block  any  visual  input.  The  eyelid  margins  normally  rest  against  the  globe,  and  the  eyelashes  are  directed  outward.
