Dear Second-opinion friends, There are two opinions about the dynamic natural eye: 1. That it tests-out as dynamic, or 2. That a the eye does NOT TEST-OUT as...

Sassy, Most people go "bonkers" if one equation is presented. That is why you need engineers and pilots involved in this. The math is "clean". The ethical part...
Dear Judy, I think that when you "kill" an eye with a drug, you get a measurement with no practical meaning. I can agree that the use of the drug can be used ...
