Night Ease™ Wrap Around Dark Red Lens Sleep Glasses – Black

Most "sleep glasses" only target a fraction of blue light, but our PC-R0301 lens is a high-performance Category 4 filter. With a Luminous Transmittance of approximately 3%, it is engineered to create a "blackout" effect for the specific wavelengths that trigger alertness, simulating total darkness for your brain even in a lit room.

Scientific sleep optimization requires blocking more than just blue light. Our spectral report shows a precise cut-off at 580nm–600nm, meaning it blocks 99.77% of blue light and nearly all green light—the two primary colors that suppress melatonin. By eliminating these "daylight" signals, you help your body trigger its natural sleep cycle faster.

Yes, it is specifically designed for pre-sleep screen use. The lens maintains a Red Signal Transmittance of 34.56%, allowing you to see red-spectrum text and images while the Blue Light Block Ratio remains at a powerful 99.77%. This allows for a "digital sunset" experience that protects your eyes from high-energy visible (HEV) light.

No. Due to the extreme light filtration required for deep sleep prep, these are classified as Category 4 (Very Dark) lenses. They are officially rated as "NOT SUITABLE" for driving at night or in twilight because they reduce visibility too significantly for safety. We recommend using them only while stationary in a safe, indoor environment.

While the tint is deep, the lens is engineered for optical precision. The certification report confirms a PASS for UV400 and utilizes Polycarbonate material for impact resistance. Additionally, the dual-layer anti-reflective coating helps minimize internal reflections, ensuring that your view of a book or screen remains crisp despite the heavy color filtration.
