Waste of time. ### 1/5 — Waste 15 mins just trying to align my eyes *2026-07-30, version 1.0.14* I’m wearing prescription glasses and I can’t see clearly without my glasses. The apps require impossible perfect alignment to measure the pd value, but I am not able to do that without my glasses. Very frustrated. I will just use a mirror and ruler I guess. ### 1/5 — Does not complete *2026-07-10, version 1.0.14* I had it in the oval but does not complete the measurement at all ### 1/5 — Not helpful *2026-07-07, version 1.0.14* Move your into the oval, you’re too far, you’re too close. My arms were aching after holding steady for so long and it still didn’t give a reading ### 1/5 — Have time to use it *2026-07-07, version 1.0.14* The scan takes way too long. I don’t have enough patience to put up with it. ### 1/5 — Terrible *2026-07-06, version 1.0.14* As many have said it just keeps asking you to put your head in the oval, no matter how much you try your head will never be in the oval. ### 1/5 — What a crack of 5hit *2026-06-07, version 1.0.14* I’m an FBSO. Took 30mins to get this to produce a result and not accurate to known clinical result. ### 1/5 — Awful *2026-05-31, version 1.0.14* Never measures. Just says put your head in the oval and when it is in the oval says you’re too far away. ### 1/5 — Does not work. *2026-05-30, version 1.0.14* Did anyone test this app? ### 1/5 — Trash *2026-05-18, version 1.0.14* Not working at all ## Frequently asked questions about Opthy ### What is Pupillary Distance (PD) and why is it important?
