lens materials

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.
