Neva Max The new anti-reflective coating Maxi protection against life s mini attacks
MAXI PROTECTION AGAINST SCRATCHES It doesn t matter how careful a person is with his or her spectacles, today, scratch-resistant lenses are must-have equipment. Scratches cause irreversible damage to lenses and can happen at any moment. When spectacles are dropped on a table, slipped into a pocket or wiped with a shirttail, micro scratches occur that degrade lens clarity. Scratches actually diffract the light, causing a loss in contrast. Transparency deteriorates resulting in reduced visual comfort Neva Max, the best performance rating on the market for endurance To demonstrate its extraordinary scratch resistant qualities, Neva Max AR lenses were subjected to real-life simulation tests, reproducing in the laboratory a lifetime of daily wear and tear. The tests simulate the normal abrasion to which lenses are subjected daily and over a certain period of time. Test protocol and results have been certified by an independent laboratory specialised in performance testing of ophthalmic lenses. 4,8 4,6 4,4 4,2 Robustness score Latest anti-reflective coatings Tested and approved by an independent laboratory NEVA MAX: A REVOLUTION IN THE OUTSTANDING NEVA ANTIREFLECTIVE RANGE Strengthening its lead in top-of-the-range anti-reflective lens treatments with Neva Max, BBGR s R&D team has achieved a breakthrough in performance.

Through its exclusive process, Neva Max offers a resistance to micro scratches that is two and a half times higher than that of a standard antireflective product and 80% higher than Neva+, the previous generation of Neva products. Transparency maintained over time Neva Max resists premature deterioration. The transparency of your lenses is maintained, ensuring long-term visual comfort. In addition to scratch resistance, Neva Max benefits from the technological advances that made Neva+ a market leader (see pages 5 and 6).

Abrasion Resistance test Lens dropped into a drum containing a mixture of abrasive dust. De-lamination Resistance test Lens submitted to an atmospheric temperature of 65 C with 95% humidity for 8 hours then returned to standard conditions (cycle repeated 3 times). Creation of cross-shaped scratches made with an abrasive point then verification of adherence of the treatment product with an adhesive.
A high PERFORMANCE TECHNOLOGICAL SUITE A true technological advance Neva Max technology draws on BBGR s expertise in the domain of nanotechnology, a feature of Neva performance from the very start. Neva Max lenses are treated with chemical components of the utmost purity with the thickness of each layer carefully calibrated for optimum results. This exclusive manufacturing process guarantees durability and stability of performance over time. 2. NEW «Max» composite layer The Neva Max innovation consists of a process for depositing a micro-aerated mineral composite layer between the varnish and the multi-layered antireflective stack. This nano-layer further reinforces the hardness of the lens, protecting it against scratching while at the same time adapting to organic lenses. It thus combines the advantages of mineral and plastic lenses with the added benefit of optimised resistance to shocks and scratches. 6. Easy cutting layer This temporary layer enables adhesion of the lens to a pad during the lens-cutting phase. 6 5 4 5. Hydrophobic and oleophobic layer This layer smoothes out micro-asperities on the surface of the lens, preventing adhesion of drops of water or finger marks. The 113 angle of contact for water and 73 for oil on the surface of Neva Max lenses are among the highest on the market. 4. Anti-static layer This conducting layer dissipates the electrostatic charges present on the surface of the lens. The dust and other particles are pushed away. 3 1. Hardened varnish Application of this intermediate layer through «soaking» renders the lenses harder and more durable. 2 1 3. Multi-layered anti-reflective stack With its 99% transmission rate and optimised multi-layered anti-reflective stack, Neva Max eliminates parasitic reflections. Substrate
Maximum comfort for you and your customers Beyond its increased resistance to scratches, Neva Max benefits from all the features that are a hallmark of Neva+. FOR YOUR CUSTOMERS: easy cleaning thanks to its hydrophobic and oleophobic properties Looking after glasses becomes easier than ever. The lenses need to be cleaned less often. Increased visual comfort thanks to optimum transmission Neva Max prevents parasitic reflections. The improved contrast increases visual acuity, reducing tired eyes syndrome. FOR YOU: More long-lasting cleanliness thanks to the antistatic layer Lenses stay cleaner longer. Visual comfort is maximised. the last technological advances in premium antireflective coatings peace-of-mind regarding the robustness of the equipment sold simplified stickerless mounting The blue protective layer covering Neva Max makes it unnecessary to use a sticker during mounting. The risk of misalignment is avoided. Simple cleaning with a soft cotton cloth is enough before presenting the glasses to their owner.
