Plus, it offers the most complete UV protection from direct as well as reflected light off the back surface of the lens.

TD2 Scratch Protection

TD2 (Tough, Durable, and 2-Sided) coated lenses offer a superior, warranted protection against scratching on our prescription safety lenses.

Polycarbonate lenses coated with TD2 are more scratch resistant than ever providing consistent protection and durability.

CRIZAL PREVENCIA Blue Filtering Lenses

Crizal Prevencia is designed to selectively filter out harmful light while letting beneficial light pass through. Why is this important? Although there are plenty of benefits of sunlight, sunlight can also be harmful to your vision and eye health including contributing to Age-Related Macular Degeneration (AMD) – the number one cause of severe vision loss and legal blindness in individuals over the age of 50.

  • Crizal Prevencia is proven to deflect harmful Blue-Violet Light by 20%.
  • Crizal Prevencia has an Eye-Sun Protection Factor (E-SPF) of 25, which means 25x times more UV protection for your eyes compared to wearing no lens at all.

Crizal Prevencia No-Glare blue light lenses work in 3 ways:

  1. Selectively filter out harmful light (Blue-Violet & UV)
  2. Allow beneficial light to pass through (visible light, including Blue-Turquoise)
  3. Maintain excellent transparency (clear No-Glare lens) for optimal vision at all times

Sapphire is similar to Crizal Prevencia in that Sapphire selectively filters out harmful blue light while letting beneficial light pass through. The difference between the two is more in the perceived color hue of the two. Crizal Prevencia has a more purple appearance while Sapphire is a faint blue. They both deflect 20% of the harmful blue light.

Blue light affects daily vision, AMD, and sleep/wake well being. If you want the ultimate in blue light protection, then you will want BluTech lenses.

These lenses go beyond Prevencia or Sapphire in protection from short wavelength blue light. Prevencia and Sapphire are anti-reflective coatings that deflect about 20% of harmful blue light.

BluTech lenses have ocular lens pigment technology infused into their lens which filters out 100% of the shortest most damaging blue wavelength light and then proportionately allows blue light responsible for the sleep-wake cycle to reach the retina.

Optifog Anti-fog Lenses

Research indicates that 75% of eyeglass wearers would appreciate an anti-fog solution for improved comfort and vision in their daily life (at work, playing sports, in transport etc.). It’s currently estimated that 1.2 billion eyeglass wearers worldwide are affected by fog problems, reflecting the potential of this technological breakthrough.

Irrespective of climate conditions, eyeglass wearers around the world face the problem of fogging when they move from a cold to a warm environment. Fogging is also a problem for a large number of professional activities, particularly those that require the wearing of masks (in healthcare, for example) or other protective equipment.

Thanks to a hydrophilic coating, Optifog lenses prevent eyeglasses from fogging up when activated by Optifog Activator, while simultaneously offering the optical and anti-smudge performance of Essilor lenses.
