Anti-Fog Safety Glasses
A fogged lens gets wiped, pushed up or taken off, and at that moment the eyes are unprotected. These safety glasses and goggles carry anti-fog lens coatings on top of full EN 166 impact protection, so vision stays clear through hard work, temperature swings and mask wear.
The N marking under EN 166 shows a lens has passed the resistance to fogging test, so it stays clear where breath, sweat and humidity would mist a standard lens.
KN styles pair the anti-fog coating with the K marking for resistance to surface damage by fine particles, so lenses survive dusty sites and repeated cleaning.
Most styles are sold singly or by the pack at a better per unit rate. 16 anti-fog rated lines are available, so kitting out a whole crew with clear vision costs less.

About anti-fog safety glasses
EN 166 is the core European standard for eye protection, and the letters on the lens tell you what it withstands beyond impact. The N marking means the lens has passed the fogging resistance test, holding clear vision under humidity that would mist an uncoated lens. The K marking means the surface resists damage by fine particles, the anti-scratch property that keeps a lens usable on dusty sites and through repeated wiping. Styles described as KN coated carry both, often on both sides of the lens.
Fogging strikes where warm moist air meets a cooler lens: hard physical work, moving between cold stores or outdoor winter air and heated buildings, and above all wearing a respirator or face mask that pushes exhaled breath up behind the eyewear. If a job pairs eye protection with an FFP respirator, an anti-fog lens is the difference between eyewear that stays on and eyewear that ends up on the helmet.
Choose spectacles for general work, sealed or gasketed goggles where dust and liquid splash are in play, over the glasses styles if you wear prescription frames, and safety readers if you need reading correction built in. Browse the full range on the products page, or read how the eye protection markings work in our safety standards guide.
