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.
