Standards and Types of Protective Eyewear

Standards and Types of Protective Eyewear

Protective eyewear refers to glasses or goggles designed to shield the eyes from potential hazards, such as flying debris, chemicals, intense light, or radiation. These eyewear types are essential in various settings, including workplaces, laboratories, sports, and recreational activities, to prevent eye injuries.

Common Types of Protective Eyewear:

Safety Glasses:
Purpose: Protect against impacts, dust, and debris.
Uses: Construction, manufacturing, or any environment with flying particles.
Features: Impact-resistant lenses, often made from polycarbonate or other durable materials.

Safety Goggles:

Purpose: Provide a more secure fit than safety glasses and protect against dust, chemical splashes, and harmful radiation.

Uses: Laboratories, chemical processing, or environments with liquid hazards.
Features: Sealed around the eyes, preventing particles and liquids from entering.

Face Shields:

Purpose: Cover the entire face, providing broader protection against larger debris, chemical splashes, or radiation.
Uses: Welding, chemical handling, medical procedures, or heavy-duty industrial work.
Features: Clear plastic shield, often adjustable for comfort.

Welding Glasses/Goggles:

Purpose: Protect eyes from intense light, heat, and radiation during welding.
Uses: Welding and other activities that involve bright light and heat.
Features: Lenses that filter out UV and IR radiation, typically with a dark tint.

Sports Goggles:

Purpose: Protect eyes from impact in contact sports or activities.
Uses: Basketball, racquet sports, or activities with high risk of eye injury.
Features: Lightweight, impact-resistant lenses, often with adjustable straps for a secure fit.


Safety Eyewear Materials and Lens Types:

  • Polycarbonate: Common in protective eyewear due to its high impact resistance and light weight.
  • Trivex: A material known for clarity and lightweight nature.
  • Anti-Fog Coatings: Important for preventing moisture buildup on lenses, especially in humid environments or for active users.
  • UV Protection: Many protective eyewear lenses include UV-blocking features to protect eyes from harmful sun rays.

Safety Eye Wear Standards and Regulations:
Protective eyewear is often regulated by safety standards to ensure its effectiveness:

EN 166:2001 is the European standard covering the requirements for protective eyewear. It is closely linked to EN 167:2001 and EN 168:2001 which specify the optical and non-optical test methods.

ANSI Z87.1: The American National Standards Institute sets criteria for protective eyewear in the U.S.

It’s essential to select the appropriate type of eyewear based on the specific hazards present in the environment.
