Just me as usual! Not sure il ever find an answer but: "A gallery Oxford spectacle is what type of spectacle?"

[chip anderson]

I suspect it's one of those half-moon shaped readers that seem to be the only 1/2 eyes available in England. Don't really know though.

The original oxford was so named because a professor at oxford came up with the idea by having nosepads added to a lornette in the 1800's. Galleries were comonly used on monocles, a mold of the cheeks and area aroudn the eye was made and a "gallery" looks almost like a ptsosis crutch served to keep the face from distorting to hold the eyeglasses in place while allowing clearance for the eyelashes. Hope that helps.

See image attached:

1st image gallery style frames
2nd image you can see the gallery on the monocle.

Not used to all these questions that people would probably say is no longer relevant so it's actually pretty fun.

yeah we're studying pretty old skool optics over here along side modern optics to keep us completly in the know, tis interesting stuff, just hard to get the answers sometimes!

I remembered reading about it on a site selling antique specs so I googled antique specs to get the images. My go to books for these questions is the old Guild Opticians Manual, and an older version of Brooks and Borish Ophthalmic Dispensing, the newer version has been updated and left some of this stuff out, for modern optics I like to go with Mo Jalie Ophthalmic Lenses and Dispensing the formulas are a bit different than those that are used state side since over here they try and use a formula for everything Mo Jalies book tends to use step by step processes and shows the derivation of a lot of formulas so you learn the concepts behind them and their use. You guys really get a top notch education that side of the pond, I'm envious.
