Meet Sleep ZM Crystal Wayfarer blue light blocking glasses, designed for both women and men who spend evenings in front of screens. The amber lenses filter up to 99.9% of disruptive blue light in the 400–500 nm range, which can help create a more favorable viewing environment for late-night activities. While not a medical device, these glasses aim to reduce glare and visual strain, making nighttime screen time feel more comfortable.
From the soft, warm tint to the light, flexible structure, every detail is built for extended wear. The Crystal Wayfarer design provides a classic, flattering silhouette that suits a range of faces, while the lenses and coatings work together to support a clear, consistent viewing experience as days wind down.
To use, wear as you wind down, and store in the included case when not in use. For care, wipe with a soft cloth and avoid abrasive cleaners to preserve the coating and clarity.
