What are special lens types and treatments?

Once you’ve selected the material and design of your lens, enhance their functionality with a combination of the following additional lens types and special treatments.

  • Photochromatic Lenses – like two pairs of glasses in one. Automatically adjust to changing light and block 100% of harmful UV rays, indoors and out. The best of both worlds in a single pair of lenses.
  • Polarized Lenses – the ultimate second pair of glasses – prescription sunglasses. Eliminate blinding glare for optimal performance and enjoyment outdoors.
  • UV Protection Treatment – like sunscreen for your eyes, UV protected lenses shield your eyes from harmful ultra-violet rays. Helps prevent cataracts, skin cancer and wrinkles.
  • No-Glare Treatment – add no-glare technology to your lenses, and you’ll look your best while reducing eyestrain and improving night vision by eliminating reflection and glare.
  • Scratch-Resistance Treatment – protects your lenses from daily use and wear-and-tear by adding scratch-resistant technology. Helps resist smudging, fingerprints, dirt and water.

What are the differences in prescription lens designs?

Just like there are different tools for different jobs, there are different lenses for different vision needs. Even contact wearers benefit from having a pair of prescription lenses. Options include:

  • Single Vision Lenses – the most common type, used for basic visual correction of farsightedness or nearsightedness.
  • Progressives (No-Line Bifocals) – a lens that has a correction for far, intermediate and near, all in one lens, without visible lines.
  • Bifocal – two focal distances (near and far)  in one lens with a visible line.
  • Trifocal – three focal distances (distance, intermediate and near) in one lens with visible lines.
  • Aspheric Lenses – lens can be thinner and lighter, improved cosmetic appearance by gradually changing the curve of the lens.
  • Specialty & Sport Lenses – specifically designed to provide safety or visual enhancement during work or recreation.
  • Computer/Anti-Fatigue Lenses – with widespread use of computers or other electronic devices, many people develop symptoms of Visual Fatigue Syndrome (VFS) or Computer Vision syndrome (CVS), including eyestrain, headaches, blurred vision and neck pain. Specialized lenses can now relieve these symptoms and provide clear, comfortable vision for computer use and other activities.

What are prescription lenses made of?

Today’s prescription lenses come in a variety of materials, from high tech to more traditional. Here’s a breakdown:

  • High Index Plastic – the thinnest lenses. Ideal for higher prescriptions and rimless frames; highly functional and versatile with attractive cosmetics.
  • Polycarbonate – the lightest weight lens material. Impact resistance is great for active wearers; highly scratch resistant, designed to resist abuse; perfect for kids 18 and under.
  • Plastic – the standard lens material. Lighter than glass.
  • Glass – the heaviest of lens choices. Functional and scratch resistant, but with the greatest risk of breakage.
