Lens technologies

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.

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.

• Extremely scratch-resistant and chemical-resistant on both sides
• Non-stick technology making eyewear easier to clean
• For challenging, dirty and/or dusty workplaces

▲ 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.

• Extremely scratch-resistant and chemical-resistant on the outside of the lens with nonstick, easy to clean technology
• Long lasting anti-fog performance on the inside
• Anti-fog performance will not diminish even after repeated cleaning
• Suitable for a wide range of workplaces

▲ 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.

• Long lasting anti-fog performance and scratch-resistance on both sides
• Anti-fog performance will not diminish even after repeated cleaning
• Suitable for environments where there is high humidity and/or frequent temperature fluctuations

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.

Flawless lens optical quality reduces eye strain, fatigue and headaches (optical class 1). Lenses with excellent optical quality are free of aberrations and imperfections - allowing the wearer to see using as close to natural vision as possible. Low-quality safety eyewear can result in poor optical clarity, one of the biggest contributing factors in eye fatigue, due to tiny distortions in the lens. Even the slightest inconsistency on the periphery can result in eyes working harder to correct or overcome these imperfections in the form of hundreds, if not thousands, of micromovements uvex prides itself on its edge-to-edge optical clarity. All lenses are manufactured in-house with 100% visual inspection throughout the production process to ensure that any deviation in optical quality can be immediately corrected.
