This next-generation multi-lens coating delivers industry-leading 99.8% light transmission per lens surface while suppressing reflections and glare. MeoLux multi-coated visors offer the highest absolute transmission speeds in the industry. MeoShield - The MeoShield ™ ion-assisted coating protects the external surfaces of lenses and offers greater resistance to scratching or abrasion in extreme conditions. MeoShieldTM meets military specifications for durability and surface hardness. MeoDrop -It is a patented hydrophobic lens coating and designed to repel water, grease, skin oils and contaminants from the surface of the lens that may impair clarity. This hydrophobic microscopic layer - applied to all surfaces of external lenses - repels water so that rain and moisture become a solid ball and simply roll off the surface of the lens. MeoDrop coated lenses are easily cleaned without stains, stay clean longer and maintain the highest level of visual clarity, ensuring that the outside environment will have no effect on your ability to select a target either in the rain, snow or any other element that Mother Nature can throw at you.
