If you are thinking about getting contact lenses and you know you have
some sort of astigmatism, you and your optometrist/opthamogist can easily
find out which type you have. First, your astigmatism is check without glasses
or lenses and then, he/she inserts a "blank" hard lens in your eye and checks
your astigmatism correction again. If you improved 100%, you had corneal
astigmatism, if you improved somewhat, you hve both, if you showed no change,
you probably have lenticular. That is how my optometrist homed in on the problem.
