I need to wear glasses while observing due to astigmatism. I don't have the cash to get something like Televue DIOPTRX lenses and upgrade all my eyepieces etc, but if I do, I'll go that way.
But in the mean time, I'm just wondering if there is any real difference optically between getting lenses done at the discount "buy one pair, get one pair free!" type places and the more up market chains and boutiques.
Yes, I know designer frames cost a lot, but they're not in the optical train. I don't care much about that.
Can you buy better lenses, with better polish, transmission, superior reflective coatings etc? The discount chain stores only really offer a choice between refractive indexes and therefore lens thickness. There's no option to check for better anti-reflective coatings...
