Here’s this exact kit on Amazon if you want to look at other reviews: https://amzn.to/3hx5gXY
I did this test and it was very, very close to the professional prescription I got from my optometrist.
This whole kit gave me my “20/25” measurement, PD distance (58.8), and my prescription.
I was actually surprised how closely it matched my prescription from my optometrist… especially since these docs go to school for years. That said, this isn’t a perfect replacement. I’ll still continue to go to the eye doc, but I use this to ‘track’ my digression (if any) of my eyesight.
