Easy to clean - nanotechnology

The inclusion of nano particles in the chemistry of uvex's scratch-resistant lens coating facilitates the creation of what's termed the "Lotus Effect" on the lens surface.

This hydrophobic effect implies that liquid remains on the 'top' of the surface, allowing it to move more freely. Lenses become significantly easier to wipe clean since the smoother surface reduces adherence, enabling dirt particles to simply slide off.

Which uvex lens coating do I need?

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 this diagram to help you choose the correct lens coating for your safety eyewear according to levels of temperature, humidity and dirt.

Find your coating:

• Select the temperature which best represents your working environment on the horizontal temperature axis
• Define the air humidity of the surroundings in percentage terms and find the figure on the diagonal axis
• Determine the degree of dirt on the vertical axis
• Join these three points to form a triangle

The part of the triangle with the largest area will show you the appropriate coating for your defined area of use.

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).

uvex core lens coatings

uvex supravision sapphire

Lenses coated with uvex supravision sapphire are extremely scratch-resistant and offer excellent resistance against chemicals. The coating system refined by nanotechnology shows a considerable increase in the non-stick properties and is therefore easier to clean. Watery and greasy dirt can be removed easily.

Scratch-resistant lenses

Lens scratches can seriously compromise your safety, raising the risk of injury.

Impaired vision makes it tougher to spot hazards, and you might end up with headaches and fatigue. uvex’s scratch-resistant coatings significantly boost the lifespan of your lenses, keeping you safe for longer and offering value for your money.
