Correction: what the lens corrects

Ex : myopia, hyperopia, astigmatism, presbyopia, etc

The lens that corrects myopia, hyperopia and astigmatism is a single vision lens.

Many types of lenses can correct presbyopia. The progressive lens is the one that provides the most natural vision.

Varilux: for complete visual freedom (panoramic fields of vision, fast and easy adaptation guaranteed).

Lens treatments: what protects the material and optimizes its performance

Hydrophobic - for easy cleaning.

Reflection-free - better contrast and better transparency.

Scratch resistant - protects the material against scratches.

Crizal is hydrophobic, reflection-free and scratch resistant.

Materials: what the lens is made of

Airwear (new generation polycarbonate) - unparallelled comfort, protection, and aesthetics.

Plastic - lighter weight and more impact resistant than glass but easy to scratch.

Glass - scratch resistant but heavy and not very impact resistant.

A corrective lens is a complete system defined by three (3) dimensions :

• the correction (what the lens corrects)
• the materials (what the lens is made of)
• the lens treatments (what protects the material and optimizes its performance)
