Safety Glasses

The Full Guide to Safety Glasses and Face Shields

This in-depth resource provides an overview of eye safety in the workplace — from colors to lenses to coating and everything in-between.
ANSI/ISEA Z87.1-2015
Help protect yourself by choosing safety glasses that comply with the most recent ANSI standard.
ANSI/ISEA Z87.1-2015, the American National Standard for Occupational and Educational Personal Eye and Face Protection Devices, is the latest edition of the standard for eye and face protection. The Z87.1 designation was first used in 1968, and the standard has been revised five times since then. The 2010 ANSI/ISEA Z87.1 revision was a dramatic shift away from product configuration requirements toward a hazard-based structure. The 2015 revision continues to focus on product performance and harmonization with global standards and fine-tunes the 2010 hazard-based product performance structure.
The ANSI/ISEA Z87.1-2015 standard is organized by the nature of each hazard: impact, heat, chemical, dust and optical radiation. This approach encourages users to evaluate the specific hazards they are exposed to and select appropriate protection based on that evaluation. Products are either standard minimum-impact or high-impact protectors. In addition to the manufacturer’s monogram, Z87 marking and impact marking, manufacturers must add lens type (welding, ultraviolet [UV] filter, visible light filter, infrared [IR] filter, variable tint or special purpose) and use protection against splash/droplet, dust and fine dust markings when claims of impact rating, specific lens type and/or use are made.

Challenges Faced by Workers Wearing Eye Protection

Lens Coatings
Help enhance the versatility and life span of eye protection by using eyewear with lens coatings available separately or in combination with others for enhanced functionality.
Anti-fog coating is designed to help reduce fogging in cold to warm temperature transitions and high-humidity environments.
Scratch-resistant coating is designed to help protect and extend the lens life when used in abrasive environments where scratches are possible.
Anti-static coating coating reduces dust and particulate attraction to the lens.
Hard coating is permanently bonded to lens to extend lens life.
Anti-UV coating absorbs more than 99.9% of harmful ultraviolet radiation.
Lens Color Guide
This handy guide will help you understand the functionality of task-specific lenses and to determine what color or tint may be best for your application and environment when it comes to workplace safety. A good rule of thumb is to choose a lens based on color opposites. For example, blue is the opposite of yellow and red is the opposite of green. So, red lenses absorb green light and yellow lenses absorb blue UV light and vice versa.
Clear

Provides excellent optics for general indoor applications where impact protection is required.

Gray

For outdoor applications where light and glare can cause eye strain and fatigue.

Indoor/Outdoor

A clear lens with a slight mirror coating serves the same purpose as the gray lens, yet allows more visible light through the lens for indoor/outdoor use. Reduces glare from artificial light.

Gold, blue and silver mirror

Use outdoors where sunlight and glare cause eye strain and fatigue. Mirror coating reflects light, reducing the amount of light that passes through the lens.

Brown/espresso

For outdoor applications where sunlight and glare cause eye strain and fatigue. Most suppliers’ brown/espresso lenses meet color traffic signal recognition requirements.

Vermilion

Enhances contrast while reducing all color equally for optimum color recognition. Ideal for indoor inspection.

Amber

Blocks the blue portion of the visible light spectrum, creating maximum contrast enhancement, particularly in low light.

Filter shades

Protection from optical radiation is directly related to filter lens density. Rule of thumb is to always select the darkest shade that allows adequate task performance.

Shades 1.5–3

Torch soldering

Shades 3–4

Torch brazing

Shades 3–6

Cutting

Shades 4–8

Gas welding

Shades 10–14

Electric arc welding

Do You Need Safety Reading Glasses?

According to the 2010 U.S. Census, there are over 81 million Americans 45 to 64 years of age. Most of these individuals will require reading glasses. A large proportion of them will need reading glasses in combination with protective safety glasses. Grainger can help you meet that need for your employees.

Save Your Company Money

Approximately 75 million pairs of plano (nonprescription) safety glasses are sold in the U.S. each year. About 10% of all users of safety glasses require bifocal safety glasses, which typically cost about $150 per pair. Help save your company and employees money by offering them safety reading glasses in place of prescription eyewear.

Calculate Your Savings

Grainger offers safety reading glasses at an average of about $20 a pair. That’s a potential $130 savings per employee when switching from prescription eyewear to safety reading glasses. If you have 500 workers, approximately 10% (or about 50 employees) could potentially require safety reading glasses. If you calculate your savings, it could be about $6500!
