Safety Glasses

Start with the protection requirement

Before choosing lens color, frame style, or price, determine what eye protection the job actually requires.

Safety eyewear can be designed for different impact, coverage, and workplace requirements. When your employer or jobsite requires a particular safety standard, verify the published rating and markings for the individual product rather than judging protection by appearance alone.

What does ANSI Z87 or Z87+ mean?

ANSI/ISEA Z87 markings are used on protective eyewear that meets applicable performance requirements.

A Z87+ marking is associated with high-impact protection under the standard. Individual eyewear can also have additional markings or features depending on its intended use.

Do not assume ordinary sunglasses or rugged-looking eyewear are safety rated simply because they use polycarbonate lenses.

Always check the specifications for the specific pair you are considering.

Clear or tinted lenses?

Choose the lens around the lighting environment.

Clear lenses are a practical starting point for warehouses, shops, maintenance areas, manufacturing, and lower-light indoor work.

Tinted or smoke lenses can make more sense outdoors or in bright conditions.

If workers regularly transition between indoor and outdoor environments, changing-light options may be more practical than switching between two separate pairs.

When do photochromic safety glasses make sense?

Photochromic lenses change tint in response to available UV exposure.

They can be useful for workers who repeatedly move between warehouses, loading docks, yards, outdoor equipment, and other changing-light environments.

They are especially appealing when carrying and constantly switching between clear glasses and sunglasses would be inconvenient.

When should you choose side shields?

Side shields provide additional lateral coverage for hazards that can approach the eye from the side.

Some safety glasses have side protection integrated into the frame, while others use removable shields.

If side coverage is required for the work, verify the construction and published protection of the individual product rather than assuming every wraparound frame provides the same coverage.

What about anti-fog safety glasses?

Fogging can become a major problem in humid environments, during physical work, when moving between temperatures, or when eyewear is worn with masks or other PPE.

If fogging regularly causes workers to remove or constantly wipe their glasses, an anti-fog design can be worth prioritizing.

Clear vision is part of useful eye protection.

Who should consider bifocal safety glasses?

Bifocal safety glasses can be useful for workers who need protective eyewear while also reading labels, measurements, drawings, instruments, or small components.

Look at the available magnification and make sure the frame still provides the fit and protection required for the job.

Why does fit matter?

Safety glasses need to remain securely positioned without creating enough discomfort that workers constantly remove them.

Pay attention to:

• frame width
• temple pressure
• nose fit
• overall coverage
• frame stability
• lens position
• comfort over several hours

Workers with wider faces or larger heads may benefit from frames designed specifically around a larger fit rather than forcing a standard frame outward.

A simple way to choose

Indoor warehouse or shop: start with an appropriate clear safety lens.

Indoor and outdoor transitions: consider photochromic.

Frequent fogging: prioritize anti-fog performance.

Need more lateral coverage: consider side shields.

Need close-up reading: consider bifocal safety glasses.

Standard frames squeeze your head: move into a large-fit option.

Workplace requirement: verify the individual product's safety rating before anything else.

The right safety glasses combine the protection required for the job with a lens and fit comfortable enough to stay on throughout the shift.
