Very carefully.
Anyone who's proficient at edging lenses to size and not needing to heat a frame to insert them should be able to do it with no problem if there is a bezel to put the lenses into, otherwise cut them to fit the hole and add a little glue. Or make the frames have a front and back half and put the lenses in between them.
There are rules. Knowing those are easy. There are exceptions to the rules. Knowing those are easy. Knowing when to use them is slightly less easy. There are exceptions to the exceptions. Knowing those is a little more tricky, and know when to use those is even more so. Our industry is FULL of all of the above.
looks like an antique ..................but is not, the lenses are AR coated.
There are no lenses in that, in fact it's a mask that is required wear for members of the International Guild of Warlocks. ( They make him look cool while checking out his latest collection of Eye of Newt.)
Don't fill this Rx correctly. Gandalf is likely to see what he looks like and demand a refund. Big red flag on the warlock thing. Tell him you don't participate with his Eyemed.
Hold it together like a watch with a separate round back piece screwed/tacked/glued +/or clipped?
We are doing a prototype in balsa, with a countersink bezel. I'll keep you up to date with photos.

Why this? With the sissors design the axis would be impossible to keep exact, same with the pd. Not to mention the design looks to be so the wearer can fold together when not in use. Any rx with a thickness that would protrude out the back of the frames eyewire would render the fold together sissors concept useless (unless of course you run a front bevel on one eye and a back bevel on the other, wouldn't that just look great!!!!). Then lets add the fish line temples that need to be adjusted with tension on the sides for a snug fit. As if a wooden frames can stand any tenson for a prolonged length of time. Nightmare design for the guy trying to rx it, just wacky enough to make a frame designer a few bucks I suppose.
Oh yeah and the guy in the pic looks pretty bummed that there are no more pickled pigs feet left in the jar.
Those are the new safety frames on the davis plan
or they help them see where his guppy went

WOW, I didn't know Jerry Huang had aged so much
These will be for my personal use as computer glasses (+2.00D with AR, CR-39 and 6 base). The lenses will be decentered for "as worn" position. If the first one comes out OK, we'll make another one in teak. That's what retirement is all about - we can fiddle with useless things

These will be standard stock lenses, and with each frame bezel made farther back, or forward, as is necessary to close the frame properly. We may have "over thought" this, but they will be fun to work on during a miserable winter. My husband owned a furniture manufacturing business years ago, and is very adept at woodworking on both large and small scale. He is also an optician, and owns a small finishing lab. We don't need any special base curves etc.

Having gone through full time optical schooling for 3 years as a young and freshly qualified optician. I have also attended classes on optical history during that time and have a pretty good memory.
The source was practical classes in Opthalmic Optics at the Northampton Polytechnic in London, way before computers existed.
Furthermore I also owned one of the then first modern type optical labs set up by the Coburn family, where we still calculated lens powers by hand for a period of 15 years.
