Combine clear distance awareness with instant close-up reading power using our bifocal prescription safety glasses. Ideal for tradespeople who require distinct focal zones without the wider peripheral adaptation needed for progressive varifocals, bifocal lenses offer a defined reading segment built into the lower portion of the lens. This design lets you focus on distant tasks through the main lens area and drop your eye line slightly to read measurements or schematics.
All bifocal safety specs in our catalog meet strict UK BS EN166 industrial safety standards. Crafted with high-impact, shatterproof lenses, these specs eliminate the hassle of switching between safety glasses and reading glasses on site. Explore our selection of classic D-segment and executive bifocal safety frames below to enhance your daily visual efficiency.

Bifocal Prescription Safety Glasses
In demanding environments like electrical installations, plumbing, and carpentry, reading fine print, digital gauges, or spirit levels is a constant requirement. Bifocal safety lenses provide a straightforward dual-focus solution: the upper area maintains crisp distance vision for navigating job sites safely, while the lower segment provides clear magnification for close-range work.
Our traditional D-segment bifocals feature a discrete reading segment shaped like a flat-topped "D" placed low on the lens. This layout ensures your primary distance viewing field remains wide and unobstructed, preventing unwanted magnification while walking or performing general site duties.
Directly mounted into durable plastic, metal, or wraparound safety frames with built-in side shields, our bifocal safety lenses are made from impact-resistant Polycarbonate or Trivex materials. Complete your custom order with anti-scratch coatings, permanent anti-fog treatments, or light-adaptive tinting for complete, all-day protection on the job.

Frequently Asked Questions: Bifocal Prescription Safety Glasses
1. How do bifocal prescription safety glasses work?
Bifocal safety lenses feature two distinct optical zones: the main upper area corrects for distance vision, while a smaller lower segment provides reading magnification.
2. Are bifocal safety glasses BS EN166 certified in the UK?
Yes, all our bifocal safety specs feature high-impact lenses and certified frames compliant with UK BS EN166 industrial standards.
3. Is the line between the distance and reading segment visible?
Yes, traditional D-segment bifocals have a subtle horizontal line separating the upper distance zone from the lower reading segment.
4. Can I get bifocal lenses with anti-fog coatings?
Yes. Our bifocal safety lenses can be customized with permanent factory-applied anti-fog and anti-scratch hard coatings.
5. What reading segment heights are available for bifocal safety specs?
Our optical lab sets the bifocal segment height to standard lower-rim positioning so it doesn't obstruct your line of sight during normal distance viewing.
