I went to do my annual eye exam today. I noticed they offer an add-on service named QuantifEye(R), which is a macular degeneration test cost $20 (not covered by insurance). Curious about the test, and because I worked a lot before computers (thought that would make my eyes aging faster than my parents), I did the computer test. The good thing is I got a good result (score 62) which is exceptional good. Interestingly, the test is developed by a St. Louis based company called ZeaVision.
I remember a short while ago, when I visited dentist, they offer a $60 (again not covered by insurance) oral cancer test. Both things made me to think that doctors (at small clinics) increasingly offer those small tests. One thing for sure this is a boom for the test developers (companies). And clinics, the distributors of test developers, can also make some money.
