Premium Anti-Fog Coatings Explained!
The number one reason why a person will choose to take off their safety glasses is due to the inability to see properly. Most commonly, this can be attributed to the safety glasses fogging up. Lens fogging is due to the difference in temperature from the lens surface and the surrounding air. When the warm air hits a cool lens, it causes condensation which makes your vision blurry through the lens or goggle. This can be exacerbated by hot and/or humid environments, sweating, or simply moving from lower to higher temperature areas.
What safety glass manufactures have done to combat this issue is to create an anti-fog coating to the safety glass lens effectively inhibiting condensation build up on the lens. This is achieved in a couple of ways: with a hydrophobic or hydrophilic coating. Hydrophobic materials repel water so when condensation builds up on a lens with a hydrophobic coating, the built-up condensation will collect into a bead and run off the lens. When a lens has a hydrophilic coating, the condensation will spread itself out on the lens. This effect allows for less change in vision has condensation develops on the lens.
Nearly every safety glass manufacture has an anti-fog lens option but through our customer reviews and experience in the safety industry, there are a few companies that have anti-fog lens that stand above the rest. Performance differences in anti-fog can be due to quality of coating, whether the coating is on one or both sides of the lens, as well as if there is additional coating applied to the lens to extend the life of the anti-fog coating. Below is our top four anti-fogs:
