Frequently Asked Questions:

Q: How long does it take for the lenses to change color in the sun? 

A: Under UV radiation, the lenses typically start to darken noticeably within 5-10 seconds and reach their darkest state in about 1 minute, providing you with instant sun protection.

Q: Do the lenses fade back quickly when moving from outdoors to indoors? 

A: Yes, very quickly. Our lenses are optimized to fade most of their color within 30-60 seconds after coming indoors, returning to a high-transparency state in a few minutes to minimize inconvenience.

Q: Will wearing these glasses make me feel dizzy? 

A: No. Our glasses use high-quality plano lenses (0 diopters) with no prescription, which won't cause visual distortion. The precise optical center design ensures comfort for long-term wear without causing dizziness or eye strain.

Q: What material is the frame made of? Is it durable? 

A: The frame is made from ultra-lightweight and highly flexible TR90 material. This material is very durable, impact-resistant, and not easily deformed or broken, while also being very light and comfortable to wear.

Q: How much do these glasses weigh? 

A: The entire pair of glasses, including the lenses, weighs only about 18 grams, making them extremely lightweight. You won't feel significant pressure on your nose bridge or ears even after wearing them for a long time.
