MORAL: Always wear safety glasses when you're putting on your safety glasses.  |
Done that one before. Luckily I do wear saftey glasses (my own glasses) before putting on saftey glasses.
We have a rule that we made up that works really well for saftey glasses. If you are within ten feet of a running motor, bolt being cut, or tensioned spring, you are wearing safety glasses. It is the simplest general rule that works the best.
Also, in our shop we see normal (polycarb lense) glasses as acceptable as safety glasses. Unless the student feels unsafe (like standing in a rainshower of chips while cutting aluminum with a blade intended for wood or while cutting wood and making a ton of sawdust) then normal glasses are alright.
Here is our reasoning, In most cases, something will not come from the top, bottom, or sides of your glasses and into your eye. In all of dangerous chip flying and dust cloud experiences I've never gotten anything in my eye wearing normal glasses. Also, it is very difficult to see through both glasses and safety glasses and can cause a headache after a while. Clear vision is more important when using tools because there is greater risk of cutting your finger off than risk of something flying in your eye.
Anyway, whatever you are doing be sure to have some sort of eye protection on. My normal glasses have saved my eyes more than a few times.
