All natural.

We all lose our fair share of sunglasses, but if you're worried about all those missing pairs ending up in that giant plastic gyre in the Pacific, then you should switch to the Zeal Ace Polarized Sunglasses. Featuring a frame made from 100% US-grown cotton, they are the world's first biodegradable sunglasses.

The cotton frame is surprisingly rigid and durable so they still feel like a normal pair of shades. Zeal also made sure the entire sunglasses were free of crude oil-based plastics, so the Ace also features E-llume polarized lens, which are made from a plant-based material called Z-Resin to eliminate the need for harmful petrochemicals in the manufacturing process.

Zeal Optics Ellume Challenge

Zeal set out to put our ellume lenses to the test in our backyard of Boulder, CO. A quick stop on Pearl Street Mall and Chautauqua Park proved to be the perfect sun-drenched testing grounds to demonstrate the color-enhancing clarity and craftsmanship in our plant-based, polarized lenses. Don't take our word for it; see for yourself.

ACE by Zeal Optics

ACE is produced from 100% US-grown cotton. After harvesting the plant from farms all across America, we ship the cotton to Italy’s renowned Mazzuccchelli family. We rely on their deep knowledge and refined skills, honed over generations, to bring to life sunglasses like never before. Paired with our exclusive, plant-based ellume lens, ACE is the greenest sunglass – EVER! And in our humble opinion, one of the most stylish as well.

I want to love them!!

  • Familiarity: I've put it through the wringer

I absolutely love that these are biodegradable and wish they worked better for me! I wanted to share my experience since I purchased them based on good reviews. This is my first pair of Zeals and I was so happy when they arrived that I wore them all the time. After about a month or 2 some of the lens coating started to bubble up and they also scratched very easily. Soon they became so loose that I couldn't look down without them completely falling off my face and I don't even have a small face... this also added to the scratches :( Hopefully it's just me??



I would probably recommend these for fashion and calm activities, but definitely not for adventure.

I want to love them!!

Study and fits great

I had these glasses for over 2 years and I wear them for hikes. They fit really comfortably and secure on my head. I have also dropped them a few times onto the rocks and they didn't even get a scratch. Highly recommend these glasses.

Great Shades!

These shades are awesome. They fit perfectly, are super sturdy, and the vision is crisp through the polarized lenses. Great buy.

Mother Earth approved

    The gentlemen from Zeal were out here at the office last Friday and let us try on a bunch of frame and lens combos. They were all top notch, the Ace is probably my favorite style. I love that you can get such a high quality polarized lens and super-durable, environmentally friendly frame for under $200. A+

    Great shades, GOOD for Mother Earth!!!

      A total win-win!!! Great looking shades, sharp hi-def lenses, and Earth friendly!!! I got these for a song @ $60.00 USD. I thought I had a large face and a small ridge on my nose, but they fit so snug and don't drop down on my face. I wish I could recommend these more than 5-stars ... So high quality for shades that will essentially disappear when lost and not end up in a landfill. ;)

      Great shades, GOOD for Mother Earth!!!

      Love these!

      Best sunglasses, make the world so pretty. Don't make it dull, instead all the colours are brighter and clearer. I have a small face but think they look good on me. Have them in desert/copper, which is a great colour to wear with anything. Would love the deep purple too!
