1. See an opthamologist next time, or at least sometimes.
2. For single vision, buy anywhere.
3. For astigmatism, multi-focal, or a more complex prescription, get a referral to a non-chain optician, a mom and pop that's been around a while, and might actually fit them properly. Most people's heads, faces, and eyes ain't symmetrical. Depending on the state you live in, the dispensing optician may be trained and licensed (states where the opthamologist lobby is stronger), or the dispensing optician can be anyone off the street (states where the optometrists have sway)
4. You can have an old pair of lenses dyed to 11% grey, save a few $$$.
5. Multi focals can impede peripheral vision acutity a bit; not a big deal, but you gotta learn to move your head a bit more.
6. You can but slip-overs, but the polarization can render some displays invisible, or at least difficult to perceive, as can any polarized lense.
I have a number of issues with my eyes, and I go to an optometrist. He's approaching his 70th birthday, and is one of those rare people who has a lifetime of experience but a forward looking attitude. He fitted me with contact lenses and I'm seen better than I have in years. I've been to plenty of opthamologists, and none of them ever put as much effort into an eye exam as this man did. Most of them are too busy to spend the amount of time with a patient as I needed.
