Whether glass or polycarbonate is better depends on the application, as each has its strengths and weaknesses:
✅ Glass – Best for Clarity & Scratch Resistance
Pros:
Cons:
Brittle – can shatter or crack on impact
Heavier than polycarbonate
Best for: Windows, aquariums, high-end displays, and places where clarity and scratch resistance matter most.
✅ Polycarbonate – Best for Impact Resistance & Flexibility
Pros:
Extremely impact-resistant (250x stronger than glass)
Cons:
Prone to scratching unless coated
Can yellow over time if not UV protected
Best for: Safety glazing, eyewear lenses, riot shields, greenhouse panels, and areas where durability and safety are key.

To determine if your Ray-Ban lenses are glass or polycarbonate, you can perform a simple scratch test. Glass lenses are more scratch-resistant and unlikely to show scratches easily, while polycarbonate lenses may scratch more easily. Additionally, you can check the weight; glass lenses are generally heavier than polycarbonate. Finally, look for any markings on the lenses or packaging that may indicate the material type.
just called rayban and they told me all original wayfarers have glass, not polycarbonate lenses.
Different manufacturers make different variations of bullet-resistant glass, but it is basically made by layering a polycarbonate material between pieces of ordinary glass in a process called lamination. More exotic versions now laminate various types of polycarbonate material together, or even use aluminium oxynitride ("transparent aluminium) or other transparent ceramics.
One advantage of a polycarbonate roof is that it is much less expensive than a glass roof. They are also easy to manipulate if you plan on installing them yourself.
Polycarbonate
