Yes! Every pair of Dusk sunglasses comes equipped with polarized lenses. Polarized lenses protect your eyes and block 100% of UVA and UVB rays. On top of that, they also make everything seem a little more clear and crisp, and cut down on glare (which makes them perfect for fishing).

Despite their lightweight design, Dusk features a 110 mAh battery capacity that allows for up to 4 hours of listening time and over 7 days of app-enabled tint adjustment time. And if the battery gets low, simply place them in the charging case or connect them to the cable provided and they will charge from 0-80% in just 15 minutes.

Dusk offers a durable design and we’re designing them to be IPX4, which means it can't be submerged in water but it can be sprayed with water.

For a more precise adjustment of tint you will need the app, but there is also a button on Dusk that enables preset tint levels. This will allow you to adjust the tint on-the-go without having to pull out your phone.
