We always recommend keeping your sunglasses in the Felix Gray hard case to avoid any damage. The lenses are high-quality CR-39, which is a plastic polymer commonly used when manufacturing eyeglass lenses. We developed a proprietary lens technology (that’s engineered and manufactured in the U.S.) that contains internal Blue Light filters, premium anti-reflective (AR) coatings, and 100% UV protection.
We recommend using the microfiber cloth you received with your sunglasses for cleaning any smudge, fingerprint, or dirt from the lens. Using lotion-free soap or dishwashing liquid with water works as well! We don’t recommend using chemical-based cleaning materials or fibers since they may scratch or damage the lens.
If your sunglasses accidentally get splashed with water, don’t worry! Our sunglasses can get wet, but we recommend rinsing with tap water after being exposed to saltwater or chlorine.
