Types of coatings
Lens coatings can be either:
• hydrophobic (moisture repelling) detergent-based coatings (which can be washed off) or
• hydrophilic (moisture absorbing)
A hydrophobic coating is soap-based and works by repelling moisture, spreading the droplets across the lens. This ultimately leads to a build up of fog on the lens, which requires cleaning to remove it. Eventually, depending on the quality of the coating, the detergent properties will be washed from the lens, rendering it ineffective.
Unlike hydrophobic coatings, hydrophilic coatings act like a sponge and absorb the moisture into the lens. The coating can hold a high amount of moisture and releases it at the edge of the lens. Hydrophilic coatings are not soap-based making them permanent (they can't be washed off).
Lenses coated with uvex supravision sapphire are extremely scratch-resistant on both sides and offer excellent resistance to chemicals. The coating system has been refined by nanotechnology and offers significantly increased non-stick properties and is therefore easier to clean. Watery and greasy dirt can be removed easily.
Lenses coated with uvex supravision excellence are anti-fog (at least 16 seconds, norm requires 8 seconds) on the inside, while the outside offers extreme scratch and chemical resistance. The anti-fog coating is permanent and won't wash off, even after repeated cleaning. The lenses are also easy to clean and less susceptible to dirt due to the non-stick nanotechnology.
Lenses coated with uvex supravision plus have long lasting anti-fog properties on both sides (at least 30 seconds, norm requires 8 seconds), scratch-resistant and anti-static. The anti-fog coating is permanent, even after being cleaned several times. This lens coating is particularly suitable for areas with high humidity.
uvex supravision extreme
Lenses coated with uvex supravision extreme have a scratch-resistant exterior and permanent anti-fog interior. Fogging is not possible as the coating does not become saturated. It is most suitable for working areas with long-term exposure to humidity and a high level of dirt.

uvex supravision variomatic
Lenses coated with uvex supravision variomatic are self-tinting filters, which automatically become darker when exposed to UV (within 10 seconds) and become lighter when exposure is reduced (after 30 seconds). Particularly suitable for workplaces where you frequently move between indoor and outdoor environments, from light to dark.
