Kahlua: The Dog Not You ...
You better click on the following link and go to the dogs, cats, birds, rats......... thread in Just Conversation and tell us what kind of dog Kahlua is and anything neat about him.

Base curves and balancing
No I did not have the base curve of a contact lens in mind. I ment that the curve that influences what the patient sees (assuming that power is accomplishe) is the Posterior Curve(s) . If one wants to accomplish image balance with dissimilar powers, one should attempt to accomplish it with curves that are most similar on the posterior surface!
The front curve is just along for the ride to give differences in thickness (which what actually slows the the light down to begin with).
Po ole Uneducated Chip
I might mention that despite some earlier controversy in another thread, the posterior curve of a contact lens is there for the fit, the anterior curve is the one for power.:idea:
