Hidden Straps for Safety Glasses
A retractable key chain gets the job done.
I use safety glasses whenever I’m working with power tools, and then I lay them down and sometimes forget where I put them. I use a retractable key chain to hold my CamelBak drinking tube and keep it from flopping around when I’m out mountain biking, and decided the same fix would also work for my glasses. I simply drilled a couple of holes in the ends of my glasses and attached a retractable key chain, which clips to my hat.
