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.
