Carhartt Braswell Bifocal Safety Glasses — 6 Lens Options

The Carhartt Braswell is a full-frame bifocal safety eyewear that combines ANSI Z87.1-rated impact protection with bottom-segment reading magnification — letting workers over 40 read labels, fastener markings, and measuring tapes without removing their eye protection. The clear lens variants are available in +1.5, +2.0, and +2.5 diopter magnification strengths in addition to a standard non-magnified clear; the gray and bronze tints come in standard (no magnification). All six variants share the same Carhartt Braswell wraparound polycarbonate frame with a permanent anti-fog coating on the inner lens surface. Vendor: Carhartt | Parent ASIN: B0D8WJ7B4B

Key Features

Bifocal reader magnification — lower-segment magnification lens molded into the polycarbonate allows reading of fine print, labels, and measurements without removing safety glasses; available in +1.5, +2.0, and +2.5 diopter for clear lens only
ANSI Z87.1+ rated — high-impact polycarbonate lens meets OSHA 29 CFR 1910.133 and 1926.102 requirements for workplace eye protection; Z87+ marking on lens and frame confirms compliance with the stringent high-velocity and high-mass impact tests
Permanent anti-fog coating — factory-applied inner lens anti-fog treatment on all six variants; reduces fogging when moving between temperature environments or working in humidity
Wraparound frame geometry — extended polycarbonate lens provides lateral coverage beyond the standard dress eyeglass profile; reduces debris access from the side
UV protection — polycarbonate lens blocks UVA and UVB radiation across all tint variants
Carhartt Black frame — durable frame in solid black finish; non-slip nose and temple grips for stable fit during active work
Three tint options — clear for indoor/variable light, gray for bright sunlight, bronze for contrast-enhanced outdoor visibility
Lightweight construction — slim profile suitable for all-day wear alongside hard hats, hearing protection, and other PPE

How Bifocal Safety Glasses Work

Bifocal safety glasses incorporate a D-shaped reading segment in the lower portion of the lens. When looking straight ahead, the worker sees through the standard impact-rated polycarbonate. When looking downward — to read a label, check a measurement, or thread a fastener — the eye passes through the magnification segment. This eliminates the need to remove eye protection for close-range tasks, which is the most common time workers remove safety glasses and expose themselves to eye hazards.

The diopter (D) value is the optical power of the reading segment. Select based on the reading distance most common in your work:

Diopter	Approximate Reading Distance	Typical Use
+1.50	24–28 inches (60–70 cm)	Early presbyopia; reading standard print at arm's length
+2.00	18–24 inches (45–60 cm)	Most common starting point for workers 45–55; reading labels and instruments
+2.50	14–18 inches (35–45 cm)	Stronger magnification; fine print, small fasteners, detailed inspection

Note: Bifocal safety glasses use non-prescription magnification segments. They are not a substitute for prescription safety eyewear. If you require distance vision correction, consult an optometrist for Rx safety glasses.

Lens Color Selection

Lens	Best Environment	Reader Option
Clear	Indoor, warehouse, shop, low-light, variable	Available in +1.5, +2.0, +2.5 diopter
Gray	Bright outdoor sunlight; neutral color rendition	Standard (no magnification)
Bronze	Outdoor variable/hazy light; contrast enhancement	Standard (no magnification)

ANSI Z87.1 Compliance

All Carhartt Braswell variants meet ANSI/ISEA Z87.1-2020 high-impact (Z87+) requirements. OSHA 29 CFR 1910.133 and 1926.102 require protective eyewear to comply with ANSI Z87.1. The Z87+ marking confirms compliance with both the high-velocity (150 ft/s steel ball) and high-mass (17.6 oz pointed projectile) impact tests. The bifocal segment does not degrade the impact rating. For chemical splash hazards, evaluate whether indirect-vent safety goggles are required; safety glasses do not provide liquid splash sealing.

Frequently Asked Questions

How do I choose the right diopter strength?

If you currently use reading glasses, match the diopter to your existing reading glasses prescription strength — most over-the-counter readers indicate their power (+1.25, +1.50, +2.00, etc.). If you are unsure, +2.00 is the most common starting point for workers aged 45–55. For very fine detail work at close range, try +2.50. If you have never used readers but find yourself holding labels at arm's length to read them, +1.50 is typically the right starting point. Bifocal safety glasses are not a substitute for an optometrist-prescribed correction — if you need distance vision correction, Rx safety glasses are the appropriate solution.

Does the bifocal segment affect impact protection?

No. ANSI Z87.1 testing is performed on the complete lens including the bifocal segment. The Carhartt Braswell meets ANSI Z87.1+ high-impact requirements across the full lens area. The D-segment is part of the molded polycarbonate — it is not a separate insert that could delaminate or reduce integrity. The Z87+ marking on the frame and lens confirms this.

Can I use these over my prescription glasses?

The Braswell is not specifically designated as an OTG (over-the-glass) frame. If you wear prescription distance glasses, the bifocal segment may conflict with your prescription lens, and wearing the Braswell over Rx frames could compromise both fit and visual quality. Workers who require prescription distance correction should consult an optometrist for prescription safety glasses rather than using bifocal safety glasses over Rx frames.

Are the gray and bronze variants available in reader magnification?

No — reader magnification is available only in the clear lens variant, in +1.5, +2.0, and +2.5 diopter strengths. The gray (CHB1120DT) and bronze (CHB1118DT) variants are available in standard non-magnified form only. If you need both an outdoor tinted lens and reader magnification, the clear bifocal Braswell is the appropriate indoor/close-work choice, with a separate tinted safety glass for outdoor tasks.

Are these OSHA compliant for workplace use?

Yes, provided the hazard assessment establishes that ANSI Z87.1-rated safety glasses are appropriate protection for the task. OSHA 29 CFR 1910.133 and 1926.102 require eye protection meeting ANSI Z87.1. The bifocal segment does not affect this compliance. Browse the full Carhartt safety glasses lineup at WC Safety.

What is the difference between the Braswell and the Carhartt Easley?

The Carhartt Braswell adds bifocal reader magnification options — available in +1.5, +2.0, and +2.5 diopter clear lens variants — that the Carhartt Easley does not offer. The Easley is a standard non-magnified safety glass in clear, gray, and sandstone bronze. If you do not need reading correction, the Easley is a simpler, slightly more economical option. Both models meet ANSI Z87.1 requirements.

How do I clean the anti-fog coating safely?

Use a soft microfiber cloth and lens-safe cleaning solution or mild soap and water. Avoid paper towels, shop rags, and abrasive wipes — these scratch the coating. Avoid solvents (acetone, alcohol) which can degrade anti-fog treatments. Do not use hot water. Rinse with cool water first to remove grit before wiping, as dry wiping over dust can scratch the lens surface.

When should bifocal safety glasses be replaced?

Replace when the lens is scratched in the central or bifocal segment field of view, shows crazing or chemical discoloration, the frame is cracked, or after any significant impact event. Do not continue wearing safety glasses that have absorbed a major impact — internal lens micro-fractures may not be visible but reduce subsequent impact resistance. ANSI Z87.1 eyewear is designed for one significant protective event; replace after an impact regardless of visible damage. Browse replacement safety glasses at WC Safety.
