1. What makes YUEDIO Optix sunglasses different from other brands?
CoastlineVision sunglasses are engineered for performance and built with cyclists in mind. With ultra-clear lenses, adaptive light technology, and a secure, aerodynamic fit — they deliver unmatched clarity, comfort, and style on every ride.
2. Are the lenses suitable for both sunny and cloudy conditions?
Absolutely. Our sunglasses feature high-contrast, adaptive lenses that perform in a wide range of light conditions, giving you perfect vision whether you're riding at sunrise, under clouds, or in full sun.
3. Are YUEDIO Optix sunglasses compatible with prescription lenses?
Yes! Many of our models come with a built-in insert system that allows you to use your own prescription lenses without compromising on style or performance.
4. Do they stay in place during intense rides or races?
Yes — every pair is designed to stay locked in during fast-paced rides, even on rough terrain. The anti-slip nose pads and lightweight wrap-around design ensure a secure, barely-there feel no matter how hard you push.
