For those of you who don't wear safety glasses I would highly recommend them. I have never wore glasses of any type and I hated wearing them while cutting or trimming. I always thought I could close my eyes quick enough if something flew up at my eye. I have been hit in the face with rocks many times while trimming, but a rock finally it me in the eye. My sight if fine, but it was a close call. I have a big red mark in my eye now. So wear your glasses even if they are a pain. Yesterday was my first day wearing glasses and I noticed my ear muffs don't fit as well and I get alot of sound in. Are most of you guys wearing plugs? I want to protect my eyes but don't want to lose my hearing either. Be safe and remember your eyes can't shut as fast as you think they can.
