How to easily widen almost any pair of sunglasses

Sunglasses come in many shapes and sizes, as do heads. There is always a chance that what you are getting may look good on your face but may just fit a bit too narrow. I know we make our sunglasses on the tight side, because we don't want them flying off of our heads. That means that they might just be a tad bit tight for those of us on the other end of the cranium spectrum. Lucky for you, our buddy Sam figured out a super easy way for you to widen your glasses up. This technique may also work on a wide variety of sunglasses, whether they have metal hinges or not. If the hinge is being stopped by the frame - This will work. Check it out!

As you can see here, stock width on the ends of the arms is right around 10cm

Note that the curvature of the frame prevents the hinge from opening past a certain angle. What we're aiming to do here is file a little portion of the frame so that the arm can open further.

Filing the hinge can be accomplished with many tools (file, Dremel, etc.) I have chosen a mill bastard file because that is what was laying around the shop. One of these can be purchased from Home Depot for around $5

And now all you have to do is take that file and flatten out the edge of the frame a tad.

Notice the notch - It may be slightly crude, but it works!

After just a couple of minutes I was able to notch out both sides of the frame in the front, which has allowed us to get this pair of sunglasses an additional 2.5CM wider. Which is going to make a HUGE difference in the end.
