bifocal safety glasses

Many listings show built-in bifocal magnification in +1.5, +2.0, and +2.5 strengths.

Frames are commonly made from polycarbonate or nylon, and lenses are described as shatterproof polycarbonate.

Several items are ANSI Z87.1 certified and list shatter-resistant or shatterproof polycarbonate lenses for impact protection.

You’ll find polarized lenses for glare reduction, auto-darkening photochromic lenses that shift clear-to-smoke, plus anti-fog and anti-scratch coatings on some models.

The bottom portion of the lens contains the magnified reading segment (e.g., +1.5 or +2.0) for close-up tasks, while the top portion is a regular lens for distance viewing.

Care instructions typically recommend wiping lenses with a polish cloth; some models are packaged with a protective fabric bag for storage and cleaning.
