Anti-Fog Glasses

Safety glasses are critical for preventing lifelong damage caused by impact, protecting the user’s eyes from flying objects, dust, metal slivers and other environmental dangers. Even minor scrapes or scratches caused by small particles have the potential to cause permanent vision problems or corneal erosions.

Did you know that the majority of on-the-job eye injuries could be avoided if workers wore eye protection? One of the main reasons as to why workers don’t wear safety eyewear is because of fogging. It’s annoying and ineffective for workers to remove their glasses and wipe off condensation constantly. Each time they’re wiping lenses, they are exposing their eyes each time to debris and other impact hazards

Anti-Fog Technology

When selecting PPE for workers, one of the most important features to consider is anti-fog technology. Fogged lenses are typically caused by hot work environments, increased humidity, physical exertion, and poorly fitting glasses. While fog won’t directly injure the worker, it can dramatically distort or reduce vision causing additional hazards.

Providing anti-fog solutions to employees Is the most effective way to ensure they wear their safety eyewear. There are a two core options to prevent safety glasses from fogging:

  • Anti-Fog Agents: Items like anti-fog wipes, sprays, and gels can be used to treat lenses before a shift, adding a layer of protection that can last for hours.
  • Built-In Anti-Fog Protection: Glasses with built-in protection feature an anti-fog coating or film that was applied during the manufacturing process. Anti-fog coatings are much more resistant and are ideal for hot and humid job sites. Additionally, glasses designed specifically for improved airflow can greatly reduce fogging issues.

Many anti-fog safety glasses will use a hydrophobic (repels water) coating – a coating that spreads fog moisture, eliminating fogging on the lens. Although effective, hydrophobic coatings are soap-based and will wash off over time. The other kind of anti-fog coating is known as hydrophilic and instead of repelling water, it maximizes surface energy to act like a microscopic sponge absorbing water to be spread evenly over the lens.

Choosing eye protection that is comfortable for the employee to wear and will not fog will encourage workers to put them on and keep them on, ensuring improved safety and compliance.
