CONTACT LENS PROGRAM

Rigid lenses:

The graph shows the tear layer 
thickness at a given meridian 
which is indicated at the lower, 
left corner of the graph.  The 
default meridian is the flat 
corneal meridian.  This meridian 
can be changed by clicking on 
any desired meridian on the 
fluorescein pattern.

You can also have the plot be a 
circumferential plot-a plot 360 
degrees around the lens, by 
clicking on  ‘circumference’ above 
the graph.  The default is at the center of the lens, 0 mm, but can be any distance from the center of the lens by just clicking at any position on the lens.
