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.

Step 1: Materials Needed

Pair of clip on sunglasses that fit your current eyeglass frames. These can be spring framed, spring loaded, magnetic, whatever. These usually are made for metal framed glasses, although some (particularly the magnetic kinds) are available for plastic.

Dissassembleable reading glasses in the proper diopter. Most stores that sell them have a little reading chart so you can try out the various strengths. If you don't use them already and just think that you might need to (like me), you probably only need +1.00. They go up +3.00 or more. The cheapest ones are only a few bucks, but you probably won't be able to remove the lenses. I bought a metal framed pair (see below) that were rimless and held together by screws. An even better alternative might be to hit thrift stores or yard sales and find a pair. Then you could be more experimental in removing the lenses.

I got smaller reading glass lenses that I needed because my first thought was to make them bifocal like by just mounting the lenses at the bottom of the frames. It turned out that the added distance between the lenses distorted the view a bit, so I wound up centering them.

There is still room for experimentation on bifocal style, but if you're going to mount them centered like I did, then your goal should be to match the size and shape of the reading glasses lenses to the sunglass frames as closely as possible.


Small pliers, eyeglass screwdriver (or a Swiss Army Knife), tape or wire, and glue (I used cyanoacrylate, but there are probably better choices - and I would love to hear of suggestions)
<p>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</p>
Certainly wouldn't have thought of doing that. Clever thinking on your part certainly, if you can get the two good pairs of&nbsp;<a href="http://www.designer-glasses-contacts.com/reading-glasses.html"> reading glasses</a> 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.&nbsp; They let you tighten the nut/bolts onto the lenses without cracking them, since they absorb some of the pressure.<br />
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.
