Terrible

This is by far the worst PD taking tool. DO NOT USE THIS TO BUY GLASSES, IT WILL MAKE YOUR PRESCRIPTION WORSE LONG TERM!! Take my advice I am an optician and bought this app to see if it actually works. IT DOES NOT. I have tried several times to compare on real patients, its a scam. You cannot take your own PD with a picture.
