Will these glasses be slipping off your face?
No. They're designed to sit firmly on your face, have better grip, and yet still be comfortable - the soft rubber covered tips grip firmly behind the ears, and the curved extendable temple arms can be angled to ensure a snug fit for any head size or face shape. Wear them under a hard hat, earmuffs, behind a respiratory mask, or at a rock concert! They aren't however meant to fit over prescription glasses - if that's what you're looking for, search "NoCry overspecs" on Amazon.

Are they comfortable enough to wear all day?
According to hundreds of customer reviews, these safety glasses are so comfortable you'll forget you're even wearing them. Their unique contoured design shape hugs your cheekbone area, and their unobstructive lightweight construction and the soft rubber nose piece let them sit lightly on your face. They won't feel bulky or awkward even after hours and hours at the workshop or construction site, operating room, school or university science lab, shooting range, racquetball court, or watching paint dry.

Since these glasses are clear, how do they protect you from UV light?
It's all about the 380nm UV protection lens coating - the highest industry standard for all UV protection in clear PPE eyewear lenses. This lens coating will shield your eyes from 90-100% of harmful UVA and UVB radiation rays, and will also protect you from UV light emitted by artificial light sources.
