Optical Lenses

Lens coatings (also called lens treatments) can be applied to any type of optical lens to enhance performance.

• 

  Scratch-Resistant

  While nothing can make optical lenses scratch-proof, an anti-scratch coating makes the surface much harder and more durable.
• 

  Anti-Reflective (AR)

  Applied to both the front and back of the lens, anti-reflective coating (also called anti-glare) eliminates reflections for better vision and fewer distractions.
• 

  Anti-Fog

  Prevents lens fogging when you come in from the cold. Reduces the amount of lens fogging caused by being hot and sweaty.
• 

  UV Blocking

  Built-in UV protection in clear or dark lenses blocks harmful UV rays to protect your eyes and their sensitivity. All ZEISS lenses feature their UVProtect Technology, so a separate coating isn't needed.
• 

  Blue Light Blocking

  DuraVision® BlueProtect from ZEISS is a lens coating with a blue light filter to reduce the amount of blue light reaching your eyes and reduce eye strain from digital displays.
• 

  Polarization

  Polarized sunglass lenses are treated with a chemical filter that blocks horizontal light rays. This eliminates glare from reflected light on water, cars, or other shiny surfaces.
• 

  Mirror Coating

  Mirror coating on sunglass lenses not only looks cool but can improve visual comfort in extreme light conditions. ZEISS DuraVision Mirror coating is available in 8 colors.
• 

  Tint

  Adding a colored tint to clear lenses can be done for fashion, fun, or for improving how you see under certain conditions. Tinted lenses can increase contrast and improve depth perception, which can be helpful when playing sports, driving, or working outdoors.

• Single vision lenses
  Single vision lenses have the same prescription power across the entire lens. Ideal for correcting myopia (near-sightedness) and hyperopia (far-sightedness).
• Bifocal lenses
  Bifocals are made up of two lenses to correct both near and far-sighted vision. Bifocals have a visible dividing line between the two.
• Trifocal Lenses
  Trifocals are made up of three lenses to correct not only near and far-distance vision but additionally presbyopia, known as the inability to focus in the middle distance (caused by loss of flexibility in the eye’s lens).
• Progressive lenses
  Progressive lenses are becoming an increasingly popular choice over bifocals and trifocals. Progressive lenses correct vision at near, middle, and far distances with no “transition zone” or visible divide.
• Toric Lenses
  Toric lenses are a type of single-vision lens used to correct astigmatism by adding cylinder correction, an additional prescription power.
• Prism Lenses
  Prism lenses correct heterophoria, a vision disorder characterized by the eyes not looking in the same direction when at rest.

• CR-39 Plastic
  CR-39 is a thermal-cured plastic polymer popular for its low cost and lightweight.
• Polycarbonate
  Polycarbonate was first used to make helmet visors and safety glasses and is now a popular choice for prescription eyeglasses. Polycarbonate is lighter and more impact-resistant than CR-39 plastic.
• High-index Plastic
  High-index plastic features a higher refractive index (how efficiently light passes through the material) than CR-39 plastic, making the lenses thinner and lighter.
• Glass
  Glass lenses have excellent optical qualities such as resistance to scratching and typically cost less than plastic. While being cheaper upfront, glass lenses today are not widely used due to their heavier, more fragile nature vs plastics.
