  • +2.5 diopter magnification for clear close-up reading

Safety Readers for Close Work

These 3M safety reading glasses combine impact protection with a +2.50 diopter bifocal segment for near tasks. The clear polycarbonate lenses carry an anti-fog coating and meet ANSI Z 87.1-2003 standards for general-purpose eye protection. A universal half-frame design fits a wide range of users without adjustable components.

Suitable for Indoor Detail Work

Workers who need magnification for inspection, assembly or reading small print while staying compliant with basic impact standards will find these appropriate. They are not intended for environments that require sealed eyewear, indirect venting or protection against liquid splash and fine dust. Buyers needing a different diopter strength or a fully framed design should consider other models.

Key Specification: +2.50 Diopter Strength

The fixed +2.50 diopter addition determines whether these glasses match the wearer's near-vision prescription. If the required reading correction differs, the bifocal segment will not provide comfortable focus for extended close work. The half-frame style and anti-fog coating are secondary to this optical parameter.

Questions about this item

How strong is the +2.50 diopter magnification when I am working close-up?

The +2.50 diopter bifocal segment adds a fixed reading power at the bottom of each lens, giving clear focus for near tasks while the upper portion remains uncorrected for distance vision.

What does the ANSI Z87.1-2003 rating actually cover on these glasses?

The ANSI Z87.1-2003 marking means the polycarbonate lenses and frame meet the standard for basic high-impact protection and optical clarity required for general industrial eye protection.

Will the universal half-frame fit over my prescription frames or sit securely on a narrow face?

The half-frame design uses a one-size universal fit with contoured temples and a non-vented wrap-around shape; it is not designed to fit over prescription glasses and may feel loose on very narrow faces.
