trivex Although trivex is clearer and lighter than polycarbonate, it's just as tough. Trivex lenses have strong impact resistance and robustness, which makes them durable and resistant to cracks and breaks. While digital sensors may filter out most ultraviolet light, there are still situations where a UV filter can improve the camera lens image quality. For example, when shooting in overcast conditions or areas with low light, a UV filter can help to reduce haze and enhance colour saturation.
Do cheap glasses block UV

It is also scratch resistant and does not require any additional scratch-resistant coating.Thermal Degradation: Polycarbonate can degrade under high processing temperatures, causing issues like discoloration, reduced mechanical properties, or degradation of molecular structure, which affects part performance. Is Polycarbonate Toxic Most polycarbonate plastics used today are not toxic. Non-food-grade polycarbonates are considered hazardous when they come in contact with food due to the release of BPA during degradation when in contact with water. In the past, most polycarbonates were made by a combination of BPA and COCl2.

Polycarbonate as a material blocks almost the entire relevant UV spectrum, meaning both UVA and UVB. The material absorbs UV radiation and does not allow it to be transmitted through.Expense. The excellent quality provided by polycarbonate lenses can be significantly more expensive than other lens materials. It can cost twice as much as regular ones, but many eyeglass wearers agree that it's worth the price.
