Polarized sun lenses

Exposure to UV radiation has been linked to several eye conditions, including cataracts and macular degeneration. Wearing sunglasses with UV protection is essential to protect your eyes from the sun's harmful rays.

Sunglass lenses are key to protecting your eyes from harmful UV.

Choose polarized sun lenses for a clear vision, great comfort, and well-defined contrast in any sunny condition, and to protect your eyes from harmful UV rays. Equipped with a polarized filter, polarised lenses will protect you from irritating reflections by reducing glare from horizontal wet surfaces.

Anti-reflective and scratch-resistant coatings

Reflections on a lens can create so-called ghost images made up of glare and concentric circles. These obstruct vision and can be annoying. Anti-reflective coatings considerably reduce these effects and increase the amount of light passing through the lens.

Anti-reflective helps increase the transparency of the glass and eliminates unwanted and unpleasant reflections. For perfect transparency and aesthetics, enhanced sharpness and contrast and visual precision, opt for our family of I-TeQ Summum coated lenses.

To meet the challenges of everyday life, our lenses are durable, dirt-resistant, and easy to clean, while offering greater visual comfort and reduced eye fatigue.

Anti-reflective coatings reduce glare caused by light (halo effect), including car headlights. Your vision will be more comfortable and will reduce eyestrain.
