Klein Tools Semi-Frame Safety Glasses — Anti-Fog, Scratch Resistant

The Klein Tools 60159 / 60160 / 60171 safety glasses combine a low-profile semi-frame with a wide wrap-around lens for ANSI Z87.1+ certified eye protection that integrates naturally with face shields, dust masks, and other PPE. Rated to three concurrent standards — ANSI Z87.1+, CSA Z94.3, and MIL-PRF-32432A — these glasses cover commercial construction, military specification work sites, and dual US/Canadian compliance requirements.

Available in three SKU configurations: clear single (60159 — $8.98), gray single (60160 — $8.98), and clear 2-pack (60171 — $14.97). The 2-pack is particularly cost-effective for site managers stocking PPE for multiple workers or maintaining a spares supply at the job box.

Variant & SKU Guide

SKU	Lens	Qty	Best For
60159	Clear	Single	Indoor, low-light, mixed environments
60160	Gray	Single	Outdoor work, bright sun, glare reduction
60171	Clear	2-Pack	Site stock, crew PPE supply, spares

Three-Standard Certification: ANSI + CSA + MIL-SPEC

Most safety glasses are certified to a single national standard. The Klein Tools 60159/60160/60171 carry three:

ANSI Z87.1+ — US high-impact occupational eye protection standard (OSHA 29 CFR 1910.133 / 1926.102 reference standard)
CSA Z94.3 — Canadian equivalent, required under provincial OH&S legislation for Canadian job sites
MIL-PRF-32432A — US military performance specification for ballistic eye protection, exceeding commercial impact standards

The MIL-PRF-32432A rating is increasingly specified by industrial customers in sectors adjacent to defense (ammunition manufacturing, aerospace, heavy fabrication) where lens penetration resistance above the ANSI Z87.1 threshold is required. For standard construction and industrial eye protection, the ANSI Z87.1+ certification satisfies OSHA requirements; the MIL-SPEC adds a compliance margin.

Anti-Fog Performance with Dust Masks

Klein Tools specifically calls out compatibility with dust masks in the product description — a key consideration for electricians and construction workers who wear N95 or P100 respirators. The exhaled air from a respirator valve-less face mask is directed upward, creating the fogging condition that makes most safety glasses unusable within minutes. The anti-fog coating on these glasses is designed to maintain optical clarity through that moisture exposure. When the coating eventually degrades, replace the glasses rather than attempting to restore the coating — degraded anti-fog surfaces are unrecoverable and compromise safety in low-visibility conditions.

Low-Profile Semi-Frame Design

The semi-frame (rimless bottom) construction reduces facial contact area and weight compared to full-frame safety glasses, improving comfort during extended wear. The wrap-around lens geometry closes the temple gap — the primary failure point on straight-temple safety glasses where projectiles and dust bypass the lens. For workers pairing these with a face shield, the low profile ensures the glasses sit correctly inside the shield without creating pressure points. See Klein Tools' Type 2 Class E safety helmet for a complete head and eye protection system from the same brand.

Frequently Asked Questions

What does ANSI Z87.1+ mean and is it required by OSHA?

ANSI Z87.1+ indicates the glasses meet the high-impact test level of ANSI/ISEA Z87.1-2020. OSHA 29 CFR 1910.133 (general industry) and 29 CFR 1926.102 (construction) both reference ANSI Z87.1 as the applicable standard for occupational eye protection. The "+" suffix is the high-impact designation — not all products sold as safety glasses carry this rating.

What is MIL-PRF-32432A and why does it matter?

MIL-PRF-32432A is a US Department of Defense ballistic eye protection specification. It requires the lens to resist penetration from a .15 caliber steel ball at 640–660 ft/s — a significantly more demanding test than the ANSI Z87.1 high-impact criteria. For industrial users, it serves as a compliance margin above ANSI, useful in high-energy projectile environments like grinding rooms, machine shops, or manufacturing operations near pneumatic fasteners.

Is the clear or gray lens better for indoor work?

Clear (60159 / 60171) is the standard choice for indoor, low-light, or variable lighting environments — maintains full light transmission and accurate color perception. Gray (60160) reduces visible light by approximately 15–20% and is more comfortable in bright outdoor or high-glare environments. Neither lens is a welding shade; do not use for arc welding operations.

Are the 60159 and 60171 lenses identical aside from quantity?

Yes — the 60171 2-pack contains two pairs of the clear lens semi-frame glasses with the same ANSI/CSA/MIL-SPEC ratings as the 60159 single. The per-unit cost of the 60171 2-pack ($14.97 ÷ 2 = $7.49 per pair) is lower than the single-unit 60159 at $8.98, making the 2-pack the better value for workers who go through glasses regularly or want a backup pair.

Can these be worn over prescription glasses?

These are not OTG (over-the-glasses) frames — they are direct-fit glasses and will not accommodate prescription eyewear underneath. For Rx wearers, choose the Klein Tools OTG safety glasses (03006 / 03007) which are specifically designed to fit over most prescription frames.

How do I maintain the anti-fog coating?

Use a clean microfiber cloth and plain water. Avoid paper towels, solvents, and acetone-based cleaners. Anti-fog coatings are permanent but degrade with abrasion and solvent exposure — once compromised, the performance cannot be restored. Replace glasses when the coating shows visible wear or fogging recurs under normal conditions.

Are these CSA Z94.3 certified for Canadian projects?

Yes — all three variants carry CSA Z94.3 certification in addition to ANSI Z87.1+, satisfying provincial OH&S requirements in Canada without requiring separate CSA-specific eyewear. The lens and frame markings include both standard designations.

When should I replace these safety glasses?

Replace immediately after any significant impact (a lens that has absorbed an impact may not stop the next one), when scratches obstruct vision, when the anti-fog coating no longer performs, or when the frame shows cracks or stress marks. OSHA does not specify a time-based replacement interval for safety glasses — condition-based inspection before each use is the required practice under OSHA 1910.132(d).
