Pupil Distance 64 vs 68.5 a big deal?

[dennis in se pa]

My recent visit to my eye glass place resulted in a PD of 64. Previously for years it had been 68.5. That's in mm. Is this a big deal? Did the eye glass place possibly make a mistake?

that's weird. I wouldn't have thought that it wouldn't/shouldn't change much if at all. If it did change that much, then I'd think you'd have double vision or one of the eyes is wandering, but I'm far from expert.

I ended up phoning then going back to the store. Turns out the machine says 67. so they are reordering them in 67. SO apparently it's enough of a discrepancy to worry about. I had had them a few days and still hadn't adjusted to them. FWIW

Go see a ophthalmologist, and skip the beginner with a machine that seems to be rather vague.

A ophthalmologist can check your eyes for a lot of thing the dime store glasses shop just cant do. I go once every year. I take my prescription to the optometrist to get my glasses made if there is any change.

Yes, I have an ophthalmologist too.

It really depends on how strong your RX is. What's your RX?

Probably measured using a harbor freight tape measure...they’re never accurate.
