Love it!

I love this app! It’s not only a handy tool but a fantastic visual aid for explaining those more complicated optical principles. My only issue is that I can’t seem to be able to enter minus power prescriptions only plus. So that does limit somewhat it’s usefulness

Best Cheater App for Optical Calculation

I technically know the math required to do these optical calculations, but this app makes it easy to just get the info at the end so you can move on with your life.

If you're in school please just learn how to do this math with pen, paper, and a calculator youll be a much better optician for it. In the real world situations where you just want to know the answer this app is indispensable.

Plus, Brent McCardle is a pretty cool guy and knows his stuff. After I learned that he created this app I was that much more grateful for his small gift to opticians everywhere.

Big mistake It doesn't work

If I could, I would rate this app no stars. I keep getting error messages when I try to use the App. The app designer said he knows it doesn't work and a new update is almost finished, but I still haven't seen one. I'm trying to get a refund.

Wonderful!

As a Optical Mgr and dual licensed optician I use this often. Its a wonderful optical tool for any optician. Thank you so so much and if you are considering buying this.... Do it! You will love it also.

Wow...where have u been :-)

Love it...
