LED Reading Glasses





Introduction: LED Reading Glasses

This Instructable entry for the Mash-Up contest will tell you how to combine your reading glasses with an LED light source. You can build it cheaply and with extreme ease. Now you can read papers in the dark or in poor light!

Step 1: Materials


(1) LED in red to maintain night vision- around $0.20 each
(1) roll of strapping tape- around $2.00 a roll
(1) pair of glasses- can be sunglasses
(1) CR2032 3V Lithium Batteries- around $0.25 each

Step 2: Constructing the LED

First you tape one of the LED wires to the battery (the longer wire goes to +, the shorter wire goes to the -) and let the other side stay free and not touching the battery. Make sure the wires are touching the proper sides of the battery because it will short circuit.

Step 3: Conecting the Glasses and the LED

Now you tape the battery and the connected wire to the side of the glasses. Be sure to leave part of the battery showing on the side the loose wire would touch.

Step 4: Working the LED

To work the light, all you have to do is press the loose wire onto the exposed battery and the LED will light up for as long as you press the wire. To shut it off you just stop pushing the wire onto the battery and make sure the two aren't touching.

Step 5: Variations

You can do the same process with another battery and LED on the other side.

I chose a red LED so as not to spoil my night vision if I use it in the dark. You can use any color LED if you choose.

    I prefer this one:


    I'm sure it looks kinda cool using red LED's and sunglasses together, But the outcome is different than the stated title.

    I also noticed that no current limiting resistors were used.

    I think I will remake this using safety glasses, And white LED's, For my personal use only of course.
    It would really come in handy, When tearing apart old televisions, ect.

    This is a fair enough idea, Just not enough work put into the circuit design, And the said project differentiates from the listed title.
    Perhaps two separate instructibles are in order here.

     Doesn't the battery hurt your head?

    Use safety glasses, as they do not prevent light, which is the purpose of sunglasses!

    i find it kind of ironic that you made these out of sunglasses,when the soul purpos of the project was to read in the dark...wicked shades though, i like this idea alot. where would i go to buy a bunch of leds? canadian tire?

    i think this is a lesson in futility because ther're sun-glasses with a light!!!

    nice I had a pair of safety glasses with LEDs that could rotate on each side worked great for night time airsoft

    Actually darkshot, you can get prescription glasses from www.zennioptical.com for as little as $8. I have several pair and they are just fine.

    The point of the mash up is to create something combining two or more seemingly unrelated topics. Reading, glasses, and light, are essentially integrated, and I therefore would not say that this is eligible. Good instructable, but not for this competition.

    How about pattern-cycling led's on rollerblades, that are powered by kinetic force (or just batteries).

    Don't need lights on your skates, but it'd still be cool. And it'd go with Zach's light helmet.

    Sadly, I'm a little late for the contest, and don't have a digi-cam right now. Or I'd probably have tried that for fun. Now to find my blades.

    Doesn't using sunglasses kinda defeat the purpose of adding light? lol Still, the concept is cool. I actually thought the LED was in the bump at the temple of the glasses, till I looked at the picture closer. I should make something like this for my dad. Probably be very helpful at work when dealing with smaller molds. (He's always got his head in some machine, so holding a light while working isn't so easy.)

    weird that you used sunglasses beacuse you have "perfect vision" as you say...but very cool instructable...this probably wouldnt work on regular glasses because most are made from metal and you would probably void the warranty on $200 dollar glasses...which is basicly the cheapest you can get perscribed glasses...(some of us arnt so lucky darnit!) but other than that awsome instructable :)

    good idea, but how is this a mashup? Reading and glasses and light do not go together at all. Nice though

    I'm pretty sure thats the whole point
    Take two seemingly-unrelated things or ideas, and combine them in a new and interesting way. but I haven't made these so I don't know how well these work but they look like they could be improved with some higher intensity L.E.D. s that were white I don't think too many of us are in a situation were we need to maintain our night vision just in one where were reading comic books late into the night without being caught or something

    feel free to make improvements and suggestions, I will be happy to hear them, just post them on the comments
