My optometrist was weird about it, presumably because he also sells frames and lenses. I went to an optometrist who doesn't sell frames or lenses and she was happy to spend less than a minute to measure my PD. I won't be going back to the former.
I go to Walmart Vision. They do all the measurements and write down everything without complaining at all for (I think) about $70. Then order a few pair from Zenni and restock every 5-7 years.
