I think I read somewhere that it used to be standard practice to go to the eye doctor (or glasses-monger?) and just try on pairs until you found one that worked, rather than getting a laser-precise eye exam. At the time I thought it was a terrible, backwards idea, but it makes sense in this context. Getting an affordable, almost-fit pair of glasses is probably a lot better than no glasses at all.
- Rinum 10y agoThat's pretty much what I did. I bought a super cheap pair (0.5 SPH) at $5, split the lenses and placed them over each other until what I saw at a distance was clear enough to read. I added up the SPH (they were 0.5 lenses, I ended up overlaying 4 pieces - so 2.0 total) and bought the resulting glasses. That was about 2 or 3 years ago and those glasses are still perfect for me.
- 13of40 10y agoI could probably do the same, but I'm blessed with one eye that's twice as myopic as the other, so I'd have do some lens swapping.
- tamana 10y agoIn the USA, most people today try on lenses until they find one that fits. Where do you use a laser to measure the eye?
- schoen 10y agoThey do have a machine to estimate the necessary correction by physical analysis of the eye: https://en.wikipedia.org/wiki/Autorefractor https://en.wikipedia.org/wiki/Autorefractor (But maybe "laser" was meant as a metaphor above?)
