Glass and polycarbonate. If you’ve browsed for prescription or non-prescription frames you know both types of lenses offer their own benefits and disadvantages. Which is the best option, though? Here’s a quick rundown of their top features to help you decide.
Comparing Polycarbonate and Glass Lenses
In the battle of glass vs. polycarbonate, let’s compare the two using these categories:
- Clarity: A lens that’s optically clearer provides a better picture. Glass is superior in this category, which is why binoculars, telescopes, and cameras use it. Its superiority doesn’t mean polycarbonate lenses don't provide a clear picture — just that glass offers more clarity.
- Scratch resistance: A scratch on your lens will affect its clarity and your frame’s overall appearance. Glass and polycarbonate can both become scratched, but polycarbonate is less scratch-resistant, making anti-scratch coatings popular among glasses wearers.
- Impact resistance: A lens with high impact resistance is less prone to cracking or shattering. While we love our frames, it’s not uncommon to drop them. Glass and polycarbonate lenses can handle occasional falls but aren’t invincible against long drops. Glass is the most vulnerable in this category. Polycarbonate is 10 times stronger.
- Weight: A lens weight becomes noticeable when wearing your frames for long periods. Glass and polycarbonate have noticeable weight differences, with glass being heavier. In comparison, polycarbonate lenses are lightweight. You may notice the weight of your glasses by feeling pressure on the nose pads and temple tips.
- UV Protection: A lens with UV protection is a must-have. While polycarbonate blocks 100 percent of UV rays, glass requires a UV protective coating. Both can offer UV protection, though.
Who is the winner of polycarbonate lenses vs. glass lenses? Both!
Each lens offers advantages and disadvantages. Choosing the lens for your frames relies on you. If you’re sensitive to your frame’s weight, for example, polycarbonate lenses may be the right choice. Of course, if you’re unsure of which to choose, you can always contact our support team for advice.
