Instructables
I realize that many (if not most) of the Instructables audience will be too young to need these, but keep it in mind - sooner or later, you will.

I'm 40 years old and I've worn glasses for nearsightedness most of my life. I'm past being too concerned about looks and contacts are a hassle, so I've stuck with glasses. I have a pair of thin metal framed, small lens glasses that I like a lot. Recently, within the last year or so, I've realized that time of my life has arrived where my arms are getting a bit too short to read comfortably and my really cool new laptop with a 1920x1200 resolution has text that is a bit hard to read when it is sitting on my desk. It's not like I'm completely farsighted (yet), but after a bit, I start to get eyestrain and I read and use the computer a lot.

I'm not ready to get bifocals. I don't really need them and I don't want larger lenses in my glasses (besides, I'm getting old, but I don't want to *look* old). I tried on a low powered pair of reading glasses, over my real glasses, and said, "Wow. That's much better." Of course, wearing two pairs of glasses makes you look a little deranged. I have nifty little spring loaded polarized sunglasses that I bought at Wal-Mart that match my frames so I thought, I'll bet someone makes the same thing in reading glasses. I looked, albeit not very thoroughly, and the best I could find was ones that clip at the top of your glasses and can flip up out of the way. My dad had pair of sunglasses like this back in the 70's and they look a bit dorky.

So, I had just bought a new pair of sunglasses because the lenses in my old ones were scratched and I decided that I would just transplant the lenses from a pair of reading glasses to the sunglass frames. Yes, this would look dorky, too, but at least it would be something that I made and invented myself.

Hi Chris, I realize you posted this a while ago. I made some reading frames very similar to these, thank you for this, but I really need them to flip up. I found these at my local eyeglass shop but they are expensive, hard to use one handed, and seemed very fragile to me when I looked at them. I investigated the patent that they have but I can't seem to make the cross bar work with the spring that my base glasses have. Have you come up with anything for flip up? here is a link to what I have see in town: http://www.clipon.com/index.php/products/flip Titanium wire, very nice, very light, I wasn't $199 convinced of their durability. Besides, I just would rather make them myself. Sarah, Sarahneider@yahoo.com

Certainly wouldn't have thought of doing that. Clever thinking on your part certainly, if you can get the two good pairs of  reading glasses it certainly is worth trying. Just would need to be conscious of the need to monitor your vision needs regularly.

I also got something in development called Flip-Frames. Check them out at facebook.com/flipframes or youtube.com.... type in Flip-Frames in the search engine. Think you might like them.

The tiny soft plastic grommets are good to keep and use.  They let you tighten the nut/bolts onto the lenses without cracking them, since they absorb some of the pressure.

I like the idea. I think I may try to figure out a way to solder clips to the actual frames that the reading lenses come in. That way the metal frames will really fit the lenses.

If you wear glasses for distance and find you can't read (ie need reading glasses) and don't have any with you, just push your regular glasses down your nose away from your eyes (or, hold them away from your face an inch or two if you are not gifted like Cyrano) and you will be able to read small print. Changing the focus distance of the regular lenses reduces their power and thus makes closer things easier to focus.

That works for me reading small print fairly close, but it has the effect of making things smaller which makes it a little worse for trying to read my computer monitor. Neat trick, though.

very nice stuff. i will make a similar clip-on for myself but not for nearsightedness, but for a special filter used in glassblowing to protect the eyes from IR and UV.
