Enhancing Productivity and Compliance

Wearing prescription safety glasses ensures that individuals with vision correction needs can work safely and efficiently. They eliminate the need to wear safety goggles over regular glasses, improving comfort and compliance with safety regulations.

Understanding Safety Standards

ANSI Z87.1 Standard

The ANSI Z87.1 standard specifies the performance criteria for safety glasses, including impact resistance, coverage, and optical clarity. Safety glasses that meet this standard are marked with “Z87” on the frame.

OSHA Requirements

OSHA mandates that employers provide appropriate eye protection for employees exposed to eye hazards. Prescription safety glasses must meet OSHA standards and be suitable for the specific hazards present in the workplace.

European EN166 Standard

In Europe, the EN166 standard covers the requirements for personal eye protection. It specifies criteria for optical quality, mechanical strength, and resistance to various hazards. Safety glasses meeting this standard are marked with “EN166.”

Types of Prescription Safety Glasses

Impact-Resistant Safety Glasses

Impact-resistant safety glasses are designed to protect against flying debris and projectiles. They are made from durable materials such as polycarbonate or Trivex, which offer excellent impact resistance and optical clarity.

Chemical Splash Goggles

Chemical splash goggles provide a seal around the eyes to protect against chemical splashes and fumes. They are commonly used in laboratories and chemical processing plants. Prescription inserts can be added to these goggles for vision correction.

Dust and Particle Protection

Safety glasses with foam or rubber seals around the lenses protect against dust, dirt, and other fine particles. They are ideal for woodworking, metalworking, and construction environments.

Welding Helmets and Goggles

Welding helmets and goggles protect against the intense light and sparks produced during welding. They feature dark lenses to filter out harmful ultraviolet (UV) and infrared (IR) radiation. Prescription safety lenses can be incorporated into these protective devices.
