I gotta try it at least once. Hold your glasses lenses between your phone and computer screen and it neutralizes them I assume.

That oughta work.
Don't tilt them X, Y, or Z!
Watch that vertex!
Junk.
I agree
Hey, it's not alternatively called a "vertometer" for nothing!
Just did it to see how it works. First pic is the prescription from the optometrist I work with and currently wearing in my glasses. Second picture is what the app got.

I'm surprised how close it is! How is the PD? Just curious. I would have thought that the vertex would make the script off. Did it specify how far away to hold the specs?Quote:

Just wait till mommy buys those back up glasses for Katy. That's some good customer service, right there.

It's like a flood of illegal immigrants into eye care.
My PD is 71.Quote:

It didnt cost me anything to do it, so figure I give it a try. As drk had mentioned, it did miss my right eye on the axis and PD was 2 mm off of the total.
I would be interested to see what happens with different power ranges. It also mentioned if you wear bifocals, progressives or have prism, you should not use this. Wonder what the results would look like if someone with a +3.00 add progressive of 5.0 BO prism used this?

The progress can not be stopped. Wether we like it or not.

....................and they claim that they have a FDA registration
They say class 1 Exempt because glasses are not regulated by the FDAQuote:
