We were able to get the PD from a WalMart but now we suspect it isn't
right. My wife tried to get glasses made at WalMart, but they only
offer lenses up to 1.67 index and she wanted 1.74 index. They used
one of those PD readers that is like a pair of binoculars or something
like that. They gave her 29.5 in one eye, 32.5 in the other, total
62. I measured her PD with a ruler and got 59, which made more sense
to me than what WalMart gave her, but with her correction, she went
with what the machine gave her. She had a pair made using that PD and
now she has some vision issues in the eye with the higher number. If
she shifts the glasses a little, the problem goes away so it looks
like they gave her a bad PD.
I think the lady who read the PD wasn't sure what she was doing. I
think she was a trainee because another employee was instructing her.
Since our regular optician retired due to health reasons, we were in
search of an alternative for her. My prescription is fairly weak(-3.5
is my highest correction) so online buying may have been a good option
for me, but she's a -11 and I recommended onilne for her only as a
last resort if she couldn't find the lenses she wanted to get locally
at a price that wasn't too expensive. We found SimplyEyeglasses.com
and had them relens a frame she already had and although they did a
good job and weren't too expensive, the PD is a problem.
Online glasses buying has its pitfalls I guess.
