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.
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?
Assuming plastic lenses:

Sorry, I forgot to say plastic. If successful I'll reveal the objective later. Thanks to all for help. Bill
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.
Take them to the optometrist?
That was a right on target response, Frank. Thank you and I'll report results later. Bill
It looked good. I know with acrylics (I do part time consulting with Lucite International) that there is some detailed literature on the internet:

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