This is amazing, however, I have the opposite problem: how do I measure for contact lenses? I've never been able to get a good fit for my contacts although my glasses have always worked well enough. The weird thing is that when I go to get contact lenses, the retailer orders them according to my glasses prescription, but subtracts seemingly arbitrary values from it to arrive at the contact lenses' values. I live in Pakistan, btw.

Do you have a stigmatism? Contacts offten don't work well with people of stigmatism.

  I do have astigmatism, actually. However, looking at the prescription of the author in the article, it appears that he does too!

    Yes, I do. I had lenses with cylinders (for correcting it) in the past and didn't like them. They're larger and asymmetric - the lower side must be heavier so that they always align correctly on your eye. With not-so-bad astigmatism, you can get away with not correcting it in your contact lenses. That's what I currently do. It works okay and brings you to a good level of vision (1.0 here in Germany, probably 20/20 in the US).

      Ahhh, that won't work for me. I started off like that, but getting cylinders made a huge difference in my contacts. I've tried the bottom-heavy ones, as well as the ones with a "1" that's supposed to be positioned at the bottom manually. Neither has worked too well. The shifting position isn't a problem, I think the bottom-heavy ones adjust fine with a little bit of practice, but the experience is never that good.

        I have astigmatism as well and the ones I use are acuvue daily moist. They apparently use some blinking technology to keep them stable. To be honest, I didn't know they were supposed to remain stable until I saw your comments, so I guess they work well for me. There are only very specific situations where I get discomfort and they misalign for me, but a few blinks puts them back in their spot.

Yes, that's a real problem - and I think those "arbitrary values" even vary by manufacturer. The best strategy I can come up with right now is ordering a pair of contact lenses based on a "best guess", possibly by an optician, based on your values for glasses. Then, check whether they are over- or under-correcting and order another pair with slightly different values under the assumption that your initial "best guess" was off. Then, compare and repeat..
