I more or less second freeskier Im getting ready to break down and get one of the ess crossbow 2x kits.

I like these because they are light. lenses are pretty much fog proof. and they will accept a prescription insert (which is good if your like me and you depend on glasses)
BUT! all eye wear has its place. Depending on what your doing will dictate what kind of eye wear you need. Would i wear a pair of ess and expect it to protect me from chemical splash/spray? No. so the full face that jack posted would be best for those situations. But the glasses style are good for general use around the shop.
I always like to have something over my eyes. Because its the time your not wearing eye protection that gets you.
Thanks
