A kind healthcare worker pointed one of these at me today at the pediatrician’s office (I wasn’t the patient.)
I was very happy that it claims everything is in range and that I zeroed out the big summary numbers on top. It was very emotionally gratifying for my fragile ego to have its blessing. Thank you Spot Vision Checker!
I was, however, mildly frustrated that the hand-held device claims I still have -0.25 D of astigmatism in each eye (within the margin of error), but it got the axis of each eye’s astigmatism exactly right. I don’t really notice or detect astigmatism now, so I’m not sure if my brain has figured out how to auto-correct for a quarter diopter of “real” astigmatism or if I was just lazy when I looked at the spot vision checker and fell into some old bad habits (is it possible to gaze into a camera astigmatically?) The device works from a meter away so it doesn’t have the same instrument myopia issues that plague the autorefractor at the optometrist. Still, it’s sad that it can look at me from across the room and detect some cursed astigmatism in just a few seconds while making chirping bird noises.
The vision-checker think’s I’m a net zero: +0.25 SPH and -0.25 CYL now, which I’ll take a “win” even though I want that CYL to go to zero. Much better than the optometrist’s initial diagnosis of -0.25 SPH and -0.75 CYL in January.
Anyway, it’s a nice “objective” confirmation that the methods here “do something” worthwhile.
