Gigi Hadid wears sunglasses with green lenses in New York City in July 2021.

Retro sunglasses have been trendy for decades, but the eyewear styles currently popular have their own spin — think colored lenses and a desire for eco-friendly practices and materials. This is in large part thanks to Gen Z, which is the newest generation to be shaping style trends and has a penchant for sustainability. In fact, Gen Z is being called the sustainability generation by some and has largely expressed a willingness to spend more on products that are environmentally and socially conscious.

So what does this mean when it comes to eyewear trends? Mainly, shoppers are more aware than ever of plastic consumption and the source of materials used to construct sunglasses. And, when it comes to the sunglasses celebrities and influencers are posting to their social media accounts, colored-lenses with retro frames are trending, particularly retro frames you haven’t seen in at least a couple decades. The eyewear shapes of the ‘90s, ‘00s, and ‘50s are all back — from rectangle, circle, and even heart-shaped lenses to the vintage cat-eye sunglasses of seventy years ago. However, the feel is geometric and modern, thanks to the colored lenses.

Eco Eyewear is on top of these trends and offers retro-inspired sunglasses made from recycled ocean plastic, recycled metal, and bio based materials — all of which are on-trend for environmentally conscious consumers. The company teamed up with Waste Free Oceans, an NGO that helps fishermen collect plastic waste in the ocean, to turn ocean trash into sunglasses. Eco Eyewear also uses recycled stainless steel and castor seeds to construct frames.

In addition to using sustainable materials, Eco Eyewear has a social mission to plant one tree for every pair of sunglasses sold with a focus on bringing trees to farmers who also benefit from the income and land regeneration the trees provide. In short, Eco Eyewear is fulfilling the desire of consumers for sustainable and socially-conscious sunglasses, while also embracing the trends — the current collection is filled with retro-inspired shapes and colored lenses. Here are some of Eco Eyewear’s styles to try for fall that are on-trend socially, environmentally, and in terms of style.
