Fancyview glasses have an IP54 rating, which means they are:
Sweat and splash-resistant (suitable for daily workouts, light rain, and everyday use)
Not suitable for swimming, showering, or submersion in water.
For sports use, we recommend wiping them dry after workouts to maintain performance.

The standard lenses are replaceable with compatible frames.
For prescription lenses, you can take the glasses frame to a local optician to have custom lenses fitted by a professional.
We recommend consulting your optician to ensure the lenses fit the frame correctly.

Yes, Fancyview uses open-ear directional audio technology:
The built-in speakers deliver sound directly to your ears, while minimizing sound leakage.
At moderate volume levels, audio is private and won’t disturb people around you.
Sound leakage increases at maximum volume, so we recommend keeping it at 70% or lower in quiet public spaces.

Fancyview open-ear glasses offer unique benefits:
You stay aware of your surroundings while listening to music or taking calls, making them safer for walking, commuting, and cycling.
No earbuds to insert, so they’re more comfortable for all-day wear and won’t cause ear fatigue.
They combine audio with stylish eyewear, so you don’t need to carry extra devices.
