Bifocal Safety Glasses +2.5 Diopter

These 3M safety glasses combine impact protection with a +2.50 diopter bifocal segment for close-up reading. The clear polycarbonate lenses feature an anti-fog coating and provide 0.999 UV protection. A wraparound half-frame design with adjustable temples ensures a secure fit for medium-sized wearers.

Upgrade from standard safety eyewear

Workers who currently switch between separate safety glasses and reading glasses gain a single compliant solution. The jump is worth it when tasks require frequent changes between distance viewing and near focus such as inspection or assembly. Dual ANSI Z 87.1 2003 and CSA Z 94.3 2002 certification covers both impact and optical requirements.

Suits technicians needing magnification

The +2.50 strength serves presbyopic users who need consistent near correction without removing eye protection. Non-vented frames limit airflow so users in high-humidity or splash-prone environments should evaluate fogging risk. Buyers requiring different diopter strengths or vented frames must select an alternative model.

Questions about this item

Will the half-frame size M design fit under a hard hat or welding helmet?

The half-frame style and medium eyewear size sit close to the face, allowing clearance under most hard hats and welding helmets without interference.

How do I adjust the temples correctly so the bifocal segment stays aligned with my line of sight?

Extend or retract each adjustable temple until the frame rests evenly on your nose and ears; the +2.50 diopter segment will then sit at the proper reading height.

When should I replace the lenses if the anti-fog coating wears off or the polycarbonate gets scratched?

Replace the glasses when scratches impair vision or the anti-fog coating no longer clears within a few seconds, as damaged lenses no longer meet ANSI Z87.1 impact requirements.
