Not affiliated either, just an amazed customer. Never needed glasses until I was in my late forties and had to start using reading ones. I bought the Personal Vision Tracker (the black one) on the Indiegogo campaign. It's not very easy to use but gives fairly consistent data if handled with care. I did not yet compare the device data with the ones from a doctor's visit. (The data for my right eye are slightly worse than for the left, and I have indeed not ideal results with standard reading glasses.) I bought prescription glasses on a UK site (I live in Europe) based on the device data. Both the reading glasses (short distance) and the computer glasses (medium distance) are perfect: I have not seen this good in years. Because of that excellent result I have also ordered the VisionCheck (the new, white one) on the Indiegogo campaign. It is purportedly easier to use, not gotten it yet. Meanwhile I had also got the Insight model (larger white one). That is for visual acuity and it confirmed that I have 20/20. Interestingly, it also showed I have a light form of tritanopia, which might explain past naming disagreements around colors between green and blue.
