Frequently Asked Questions (FAQ)

1. What is the difference between UV400 and polarized lenses?
UV400 refers to the ability of the lens to block light up to 400nm (100% UV protection), whereas polarization is a filter that eliminates horizontal glare from surfaces like water or roads. A high-quality lens should ideally offer both.

2. How can I verify if a manufacturer’s sunglasses are truly UV400?
Request official test reports such as CE (Europe), FDA (USA), or AS/NZS 1067 (Australia) certifications. Professional manufacturers will provide spectrophotometer results showing the light transmission curve.

3. Why is TR90 a preferred material for UV400 sunglasses?
TR90 is a thermoplastic material that is incredibly durable, flexible, and lightweight. It holds UV400 lenses securely without warping, making it ideal for sports and daily-wear sunglasses.
