Prevent Glasses Falling Off Your Face With Hot Glue


Introduction: Prevent Glasses Falling Off Your Face With Hot Glue

...not quite what it sounds like.

I have a pair of entirely plastic framed glasses. When looking down at things (especially over the side of a pitching boat, facing the sea), these glasses would start to slide off my face. They fell off a couple of times, so I put a block of Sugru on the inside of each arm to make the arms grip my head better.

This worked very well, for a time, but the plastic arms were so shiny that the Sugru eventually just peeled off.

I decided to have another proper go, but I'd run out of Sugru in the interim, so I just used hot glue. This instructable is pretty simple, but I guess it might help someone, and I couldn't find another example of it.

Step 1: Remove the Arms

Remove the arms from the glasses. You don't have to do this, but it does make working on them easier.

Step 2: Cut and File the Arms

You should prepare the surface of the plastic so that the glue (or Sugru) can "grip" it better. This is called "keying" the surface.

I used a round rat-tail file, and a hacksaw. You could use anything that will scratch or cut the plastic, like sandpaper.

Step 3: Apply Hot Glue

Put blobs of hot glue on the inside of the arms. I found this easiest to do in one big lump, as the surface tension of the glue made it into quite a smooth shape. Once on there, I waited for it to cool, and used the cooler, fatter end of the glue gun to shape and mould the blob, as shown in the photograph.

Tip: Start with a thin "blob" of glue -- you can always add more later. I tried blobs around 2mm thick first, before bulking them out to 4mm.

Step 4: Reassemble

Once the glue has cooled, you can remove any of the last little bits of cruft with a sharp knife, and put the arms back onto the glasses. I also put a dab of threadlock on the screws at this stage.

Then, your glasses are ready!

    I just got glasses and I saw the rubber band thing it works awesome. Thanks much lol. Tired of having to lift them back up

    Great. So much more attractive than using rubber bands on the arms. Thank you
