The addition of nano particles in the chemistry of uvex's scratch-resistant lens coating helps to create what is known as the "Lotus Effect" on the surface of the lens.

This hydrophobic effect means liquid rests on 'top' of the surface so is able to move more freely. Lenses can be wiped clean much more easily as the smoother surface means less adherence so dirt particles simply glide off.

The safety market is saturated with products all claiming to have similar performance values, however, some safety eyewear companies are resorting to “magic tricks” to fool an audience about its products anti-fog capabilities.

This video highlights the “trick” that is taking place, whereby uvex safety glasses with anti-fog lens coating are being compared to competitor products to demonstrate the effectiveness of their lens coating claims.

The “trick” is that like-for-like lens coatings are not being used for the demonstration thereby, casting doubt on the capability and performance of uvex products. This is an unfair comparison and uvex don’t want its customers to feel deceived by what they are seeing.

uvex has developed 3 core lens coatings and several special coatings each with their own formula. The flow process used to apply the coating allows different coating combinations to be applied, making them application-specific for maximum effectiveness.

Different workplaces require different lens coatings for safety eyewear due to variations in working conditions.

uvex has created a simple-to-use guide to help you select the right lens coating for your workplace. Use the diagram shown in this video to help you choose the correct lens coating for your safety eyewear according to levels of temperature, humidity and dirt.

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).

▲ uvex supravision sapphire

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.

▲ uvex supravision excellence

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.

▲ uvex supravision plus

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.

Scratches on your lenses can directly impact on your safety, making you more vulnerable to injuries.

If your vision is obscured, your perception of hazards is compromised and you may also experience headaches and fatigue.uvex scratch-resistant coatings significantly extend the life of the lens, keeping you protected for longer and providing excellent value for money.
