Drill sunglasses?
 

What would be a safe way to drill a hole in the lens of sunglasses without
shattering the lens?
The hole can be 1/4 or 1/2 inch in diameter.
Maybe a hot iron?
Maybe water cooled drill?
Maybe a drop of acid?

I'd go with a low speed, lower pressure, diamond tipped drill.

plastic or glass lenses? if glass, tempered?

Glass or plastic? If plastic, there is no problem. You can use a regular
twist drill. Start with a small drill about 1/8 and work up.

Glass is going to be a problem as glass lenses are tempered. If you require
a glass lens then you are probably going to have to get a lens blank from an
optician and drill it while the glass is soft.

Now why in the heck are you drilling a hole in a lens?

About the time I had mastered getting the toothpaste back in the tube, then
they come up with this striped stuff.

Sorry, I forgot to say plastic.
If successful I'll reveal the objective later.
Thanks to all for help.

We were taught to drill plexiglass with a regular drill and lots of **liquid
soap**

But a lens is awful small to hold for a 1/2" drill.

That was a right on target response, Frank.
Thank you and I'll report results later.

It looked good. I know with acrylics (I do part time consulting with Lucite
International) that there is some detailed literature on the internet:

I believe most lenses are polycarbonate but machining plastics is fairly
general.
