Seeing the laser dot

I am doing a project trying to laser engrave clear acrylic. Lots of experimenting and failures so far. Was trying to do a manual focus based on the laser dot size. This problem/question applies to all my laser efforts too.

How am I supposed to determine the size or location of the laser dot with the laser protective glasses on? With my laser glasses on I cannot see the dot. To focus the dot will require looking at the size of the dot for a few minutes but I get the impression this is not safe. What am I missing here? Thanks.

You can use a camera to view the laser indirectly—the one on your phone, for example.
