Sustainable Manufacturing

Some or all of the energy used to make this product is produced via renewable energy sources such as solar, wind, or hydropower.

Plant Based Resin

Plant Based Resins are used as an alternative to fully-synthetic plastics. Instead of using Petroleum as the main base ingredient to form plastic, some companies have started replacing a portion of the ingredients with plant and vegetable extracts. This lowers the amount of resources extracted to create purely synthetic products, and often provides a use for agricultural byproducts such as corn or flax. Some plant based resins are made from 100% plant materials, and can be composted in industrial facilities. EarthHero recommends checking with your local compost facility to determine which items are safe to compost.

About the Company

Zeal Optics

Started in 1996 by adventure-seekers and nature-lovers, Zeal has always been guided by three main pillars: Use Less, Give Back, and Explore More. Their admiration and gratitude for the planet is infused into each pair of eyewear, inspiring users to get outside and preserve the wild spaces to which they go. Plus, it is hugely important to the Zeal community that the positivity that the outdoors brings them is reciprocated. They partner with sustainability-focused non-profits like 1% for the Planet, the National Forest Foundation, and POW to ensure that the mark they leave on the planet is a good one. Zeal also works with organizations to increase access to nature for those who may otherwise not encounter such opportunities.

Zeal tests their sunglasses in some of the gnarliest conditions with athletes and explorers alike, but you don’t have to be a dare-devil to embody their ‘Explore More’ ideal. Whether it’s on the side of a mountain or lounging by the sea, Zeal Optics will work to elevate your view and inspire a sense of purpose!
