Frequently Asked Questions

• What makes Zeal Optics' eyewear more sustainable than conventional sunglasses?

  Zeal centers sustainability in materials and manufacturing, using plant-based Z‑Resin (castor bean oil), See Grass frames made with up to 70% agricultural grasses, recycled plastics, and recyclable stainless steel in the Metals Collection. Their labs use closed‑loop processes to recycle fluids and shavings, and biobased lens options like Ellume Polarized reduce reliance on petroleum‑derived plastics.
• What lens technologies does Zeal use and how do they affect performance?

  Zeal offers Optimum Polarized lenses for high‑contrast, glare‑reducing vision with Permashield hardcoats and Everclear anti‑fog treatments, plus Ellume Polarized plant‑based lenses and Automatic+ photochromic options for changing light. These combinations prioritize UV protection, glare control on water and snow, and clearer terrain definition without sacrificing durability.
• How do the Metals Collection, RLs, and See Grass lines differ in design and use?

  The Metals Collection delivers forged stainless steel aviator and classic silhouettes with Hexetate or ceramic nose pads for refined comfort, while RLs are rimless, performance‑oriented frames with dual sliding rails for expanded peripheral vision and adjustability. See Grass (models like Hondo and Cumulus) emphasizes a natural aesthetic and high plant‑content frames for a sustainable, everyday performance look.
• Are Zeal sunglasses and goggles suitable for mixed activities like skiing, fishing, and running?

  Yes, Zeal’s premium polarization and optical clarity reduce glare on water and snow, and Automatic+ photochromic lenses adapt to variable mountain light. Sport‑focused touches like ProFlex rubber bridges and temples, ultralight Z‑Lite frames, and sport shield RL styles keep frames stable during running, biking, and dynamic snow use.
• Can you get prescription lenses and adjust fit on Zeal frames?

  Zeal supports prescription options through their closed‑loop prescription lab, and many frames are designed to accept prescription lenses or inserts where specified. Fit features like ProFlex rubber bridges/temples, dual sliding rails on RLs, Z‑Lite ultralight frames, and Hexetate/ceramic nose pads in Metals help dial in comfort and retention for active use.
