Prescription Safety Glasses Model 691

The model 691 is made with the state-of-the-art Digital-Surfacing lens production method. To create these lenses an advanced digital technology is used to resurface the lens allowing for greater precision over the entire lens surface. This enables your prescription to be the exact same strength on the very outer edges of your lenses as it is in the middle. Surfacing the lenses this way provides you with more visual comfort, improved peripheral vision, sharper definition and less eye fatigue.
Model 691 is a stylish wrap around safety frame. Comes with a hard storage case, a soft case/lens cloth and an adjustable retainer cord. Meets ANSI Z87.1-2003 standards when fitted with optional polycarbonate lens (sold below).
