I really recommend you buy your eyeglasses over the internet. There are several sites selling glasses, and despite the fear mongering that you'll see, they are great. Search words include: prescription AND glasses OR gogglesYou have to remember that eyeglass prices and ESPECIALLY frame prices are artificially inflated. There is only one significant company that makes ALL the frames.Beware of sites that DO NOT ASK for your prescription strength - they're in business just to give the real places a bad name.You will need the following information from your prescriber. DO NOT let them bamboozle you. You paid for the exam, the results of that exam are YOURS.Prescription strength for each eye (assuming you have two eyes). For bifocals you'll need two strengths for each eye. Sphere (SPH) for each eyeCylinder (CYL) for each eyeAxis (AXI) Add for each eye. Note, they sometimes give you a negative number. Just ask them for the positive version.And something called interpupillary distance (PD) which is nothing more than the distance between your pupils. It's usually around 65 mm. if its much lower, then they probably measured it from your pupil to your nose on each side, so just double that number. Now, if you look at something close up, your eyes cross slightly, which brings your pupils slightly closer together, so galsses for close work, like reading glasses should have a slightly reduced PD
Save Money When Buying New Spectacle Frames
I doubt you could do that since the Pi isn't designed to run heavy software. Apologizes for my late reply.
It's not the frames that are the biggest expense ... when you have special requirements, such as super thin lenses (due to weight/thickness), or want the progressive type of bifocal, it's the lenses that are outrageously expensive. I can find any number of frames I like for less than $100 (sometimes, less than $50), but my prescription typically adds at least $250 to the bill. I've had frames in the past that I really liked and wanted to fit with new lenses and couldn't get anyone to do that, even though the frames were expensive and came from a traditional eyewear manufacturer. One thing I've noticed in recent years is that bells & whistles I don't want are automatically added -- for example, anti-scratch coating. I NEVER got scratches on my lenses until this coating was added! It reminds me of trying to buy either a car or computer these days .... all the "add-on's" I don't want and really don't want to pay for, but are forced into because that's what's available now as "standard" or "basic." - RustyRoller
Be sure any frame you buy; cheaters, sunglasses or whatever have a serial # on them. That improves the odds that you script can be cut to fit. Look for number stamped on inside of temple piece. - KelaA
Cheap frames are cheap for reasons. Beware depending on your prescription you may not be able to do it. Also beware your headsize if you do that
