Eyeglass Lens Materials & Coatings in Cambridge, Ontario

When patients search for lens and frames in Cambridge, Ontario, most of the confusion is actually about the lens—not the frame. Lens material affects thickness, weight, and impact resistance. Coatings affect glare, clarity, and how easy lenses are to clean. Here’s a straightforward guide to help you choose confidently—whether you’re updating prescription glasses, switching into progressives, or building a “best everyday pair.”

Best Lens Materials for Everyday Glasses

• Standard plastic (CR-39): A solid option for mild prescriptions—good clarity and cost-effective.
• Polycarbonate: Lightweight and impact-resistant—often recommended for kids, sports, and active lifestyles.
• Trivex: Similar benefits to polycarbonate with excellent optical clarity—great if you want both clarity and durability.
• High-index: Designed to reduce thickness and weight in stronger prescriptions—often improves comfort and cosmetics.

Coatings That Most People Benefit From

• Anti-reflective (AR): Reduces glare from headlights and screens; improves crispness and cosmetic appearance.
• UV protection: Helps protect the eyes and surrounding tissues from UV exposure (important year-round in Ontario).
• Scratch resistance: Adds durability for daily wear and helps lenses keep clarity longer.
• Smudge-resistant / easy-clean: Makes lenses easier to wipe and keeps them clearer throughout the day.

Do “Blue Light” Lenses Help?

For many people, comfort during screen time is more about dryness, blink rate, and working distance than any single coating. If you’re on screens often, the best solution may include: a lens designed for computer distance, an AR coating to reduce reflections, and advice on lighting and breaks. During an eye exam, we can recommend what actually fits your symptoms and routine.

How to Choose the “Best” Lens Package

The best lens choice depends on your prescription and how you use your eyes daily. In a typical Cambridge routine (driving, screens, indoor/outdoor transitions), most people do best with: a durable material, AR coating, UV protection, and easy-clean performance. Strong prescriptions often benefit from high-index for comfort and appearance.
