Lid Retraction 

When photographing the eye, the client needs to be observing the center of the lens with the eye being 
photographed. Many people have a dominant eye that will be looking around at random points, so it is 
always best to have the eye not being photographed covered, either with a handheld paddle occluder, or 
(preferably) the clients own hand on that side. 

The preferred method of lid retraction for those clients who cannot open the eyelids sufficiently, is to use 
assisted lid retraction. In this method, the client is asked to cover the opposite eye (eye not being 
photographed) with the hand on that side and with the other hand gently pull down a bit on the lower lid. 
Meanwhile the photographer uses a cotton-tipped applicator to roll the upper lid away from the eye in 
order to reduce glare and reflections. 

 

 

Another method is for the photographer to retract both eyelids using two cotton-tipped applicators:
