For those in the know, is there also something called an optical or optic center that's measured, or is that the same as the pupillary distance? Last time my lenses were done, they had to redo because what they called the optical center was off. I thought it was described to me as where your eyes hit the lenses vertically, as opposed to the horizontal measure of the PD. Am I making this up??

I cannot even get a local "mall" "Instant - make your glasses onsite" place to get my prescription right (I have had 3 failures at that - and no such "instant - grind the lens onsite" ever made me a pair of lenses that worked). I later talked to a person who worked at one of those places and she told me that they only tried to get the lens approximately close, and would loose money if they actually ground lenses to the prescriptions because of the time involved to get the last 25% of the curve right.
I have severe astigmatism (so high I cannot wear normal contacts) and need a fairly high correction. In order for me to be able to properly see I also need a custom base curve (the base curve is the curve ground on the front of most lenses - and then they grind the correction into the back of the lens). The vast majority of these places only use standard base curve blanks - which can affect how well you see and if the lenses magnify or shrink the world through the lens.
A high refractive index lens, and then various coatings also help.
If you only need a low correction lens, do not have much astigmatism, and could not really benefit from some of the special coatings - then you will probably do OK if you can get them the right dimensions.
In my case - I work with a local eye doctor who pays special attention to ensure I get the right lenses (and they take longer than most of the glasses they provide). He uses a specific lab for "highly technical" lenses such as mine, which is different than their normal lab for most of their other glasses.
I gladly pay the cost of this - good eyesight is worth its weight in unobtanium. Such a pair of glasses was the difference in me being a good enough international level whitewater slalom judge to be chosen to be an official at 2 world championships and an Olympics.
To put this in perspective - just my lenses and coatings alone typically cost more than most people pay for an entire set of glasses (including the frame)
I guess it all comes down to how much you value good clear eyesight. I also wonder how many people have actually had a "near perfect" prescription so they could see the difference it makes versus "just good enough."
Edited to add this comment: You do not always get what you pay for (some people/businesses do rip you off); but, you never get what you do not pay for.
Have a great day,
Perry

You mentioned High Index lenses... theirs were way cheaper than the place I went online even. I've had no issues at all and am very pleased with my glasses. I buy glasses once or twice a year because A) I buy <$200 glasses, and B) I'm very hard on them. I also like leaving a pair at work, a pair at my desk, and a pair on my bedside stand.
