Bi-Focal Safety Glasses

Bi-focal safety glasses — impact protection with reading magnification

Bi-focal safety glasses are standard AS/NZS 1337.1 impact-rated frames with a magnifier segment built into the bottom of the lens. They solve a common on-site problem: workers who need reading correction for measurements, packaging labels, or mobile-device screens, but don't want to switch between prescription safety eyewear and general pairs throughout the day.

How to choose a magnification power

• +1.00 to +1.50 — early reading correction. Workers in their 40s, light close-up work.
• +1.75 to +2.25 — the most commonly stocked range. Standard for small-print labels, calipers, and tablets at arm's length.
• +2.50 to +3.00 — heavier correction. Fine detail, close-range assembly, schematics.

When in doubt, match the power to the worker's existing reading glasses. The bi-focal segment only sits in the lower portion of the lens — distance vision is not affected and impact protection across the full lens remains AS/NZS 1337.1 compliant.

When bi-focals beat a dedicated pair

Trades where workers repeatedly switch between distance and near tasks — electrical, plumbing, maintenance, warehousing — benefit most. If a worker only needs reading correction for one task at a fixed workstation, a dedicated pair of standard safety glasses plus magnifiers kept at the bench is often cheaper.

Not a prescription replacement

Bi-focals handle presbyopia (age-related near-vision loss). They don't correct for astigmatism, distance vision, or complex prescriptions. For workers who need full prescription lenses in a safety frame, request a quote and we'll coordinate with the manufacturer.

Standards & compliance

Every bi-focal pair we stock is certified to AS/NZS 1337.1 with the bi-focal segment moulded into the base lens — not a stick-on insert. The standard mark is printed on the frame and remains valid for the life of the product.

Frequently asked questions

Can I get anti-fog bi-focals?

Yes — most ranges are available with anti-fog coatings, and some include foam gaskets for dust-heavy work. Filter by AF on the product pages.

Will bi-focal segments affect distance vision?

No. The magnifier occupies only the lower inner portion of each lens. Above the bi-focal line, the lens is standard non-corrective impact glass.
