Before I was a watchmaker I didn’t think much of safety glasses. I remember wearing them in science class in school. As a kid I mowed lawns, used power tools without ever thinking twice about safety glasses. — As a watchmaker my eyes are very important to me. I would have to change my career if I lost my eyesight. Now I find I wear safety glasses for everything. I wear sunglasses when I drive, I where safety glasses to mow the lawn, or when I cut a board. At work I use them when I polish or turn on the lathe. The last thing I need is a little piece of metal lodged in my retina!
You’ll notice two pairs of glasses there. The one in the foreground I use for most activities. It provides good coverage of my eyes but it has one downside, it doesn’t let me get close to my work like I need to when using the lathe. For turning operations I use the pair in the back. They had a single plastic lens but with an adequate support system that they function well even after I removed the lens from one side. This allows me to wear my loupe on my right eye while protecting my left eye. (The loupe fully covers my eye and provides protection by itself.) It looks pretty funny when I’m wearing it, but alas, what is the price of an eye?
