The Importance of Safety Glasses on the Worksite
Eye injuries are all too common in the workplace: the US Bureau of Statistics reports over 20,000 eye-related workplace injuries a year. Such injuries cost employers $300 million annually in lost productivity, workers compensation, and medical treatments, and approximately 20 percent of eye injuries result in temporary or permanent loss of vision.
Multiple factors cause workplace eye injuries, including airborne dust and particles, sparks from tools or power equipment, flying objects, ultraviolet radiation, and chemical contact. Properly fitted safety glasses and eyewear could prevent up to 90 percent of all eye injuries, making safety glasses some of the most important personal protective gear (PPE) on the market.
Safety Glasses Standards
Safety glasses standards are set by the American National Standards Institute (ANSI) and enforced by the Occupational Safety and Health Administration (OSHA). ANSI Z87.1-2003 covers current safety glasses standards, which require:
- Frames and lenses be stronger than regular glasses
- All safety glass lenses be impact resistant
- All frames be heat resistant and prevent lenses from being pushed into the wearer's eyes
- All safety glasses be correctly fitted
Most of the best safety glasses have lenses made from plastic polycarbonate for increased strength and durability. Protective eyewear that conforms to ANSI safety glasses standards must carry the manufacturer's marking, along with a “+” sign if the lenses are impact rated. Additional markings on safety glasses include:
- "V" for photochromatic lens
- "S" for special purpose tinted lenses
- "W" and shade number for welding glasses
- "U" and scale number for ultraviolet filters
- "L" and number for visible light filter
- "R" and scale number for infrared filters
Types of Safety Glasses and Eyewear
The type of safety glasses you need will be determined by your work environment--the best safety glasses for a warehouse will be very different from the polarized safety glasses needed for outdoor work sites. Here are some of the best safety glasses and eyewear for specific situations.
Low Light Environments
The best safety glasses for low light environments have tinted amber lenses to remove blue light. Such glasses often protect against accidental welder’s flash burns, such as the Rad-Atac Safety Glasses from Radians.
Manufacturing and Construction Safety Glasses
Manufacturing and construction safety glasses have to protect against a wide variety of threats, including impacts, dust and airborne particles, welding flash burns, and chemical exposure, with exact requirements depending on job responsibilities and the work environment. Examples of construction safety glasses include:
- Radian’s Mirage Small Foam Lined Safety Glasses: Designed to protect against airborne particles, debris, and eye irritants while offering impact protection.
- Radian’s Rad-Sequel Safety Glasses: Made from impact resistant polycarbonate with anti-fog lenses.
- Radian’s Clear Lens Mirage Safety Eyewear: Offers impact resistant and wraparound lenses for an improved orbital seal.
- Radian’s Light Blue Rad-Atac Safety Glasses: Provides both impact resistance and protection against accidental welding flash burns with a 1.7 infrared filter.
Polarized Safety Glasses
Bright sunlight and other sources of ultraviolet light damage the eyes over time, while causing glare that reduces vision and increases the risk of accidents. Polarized safety glasses filter out the bulk of ultraviolet rays, making them ideal for outdoor work environments. Examples of polarized safety glasses include:
- Crossfire Infinity Safety Glasses with polarized brown lenses
- Rad-Atac Safety Glasses with indoor/outdoor lenses and impact resistance
- Extremis Foam Lined Safety Glasses with clear anti-fog lenses
“Over the Glasses” Safety Glasses
Prescription safety glasses are the best choice for employees with vision problems, but are not always available. When you need eye protection for an employee or guest already wearing glasses, the next best safety glasses are OTG, or “over the glasses” eyewear. OTG safety glasses are large enough to be worn over existing glasses, and may come with side shields to protect against high-impact threats. Examples of OTG glasses include Radians Chief OTG Glasses and Stealth OTG Safety Glasses, which include ultraviolet protection.
When Safety Glasses Are Insufficient
Even the best safety glasses have their limitations. In environments where protection is needed against welding flares, chemicals, or infectious agents, face screens, face shield, and visor/brow-guard combinations are worn as secondary protection alongside safety glasses. Check ANSI safety glasses standards to determine what kind of eyewear protection is right for your work environment.
