If you've ever had to deal with the inconvenience of switching out your bifocals for your safety glasses or had the cumbersome experience of wearing your reading glasses beneath your safety glasses, there is a better way to see and keep your eyes protected. Bifocal safety glasses provide a solution to the dilemma of switching between glasses so you can see or wearing safety glasses to protect your eyes. Bifocal safety glasses work by providing magnification at just a portion of the lens so that you can use the bifocal capability when you need it. Bifocal safety glasses come with designs suited to your specific needs. Some bifocal safety glasses have magnification at just the bottom portion of the lens while others have the magnification at the top and bottom of the lens. You'll also be able to choose from a range of magnifications from brands like Smith & Wesson and Pyramex.
