Quality sleep is essential for memory, mood, immune function, cognitive performance, and overall well-being. Conventional blue-blocking eyeglasses primarily reduce shorter blue wavelengths. Our proprietary ophthalmic lens is designed to extend blue-light attenuation across approximately 440–510 nm, while maintaining over 80% visible light transmission for clear, comfortable vision. This broader, targeted attenuation is intended to better support the body’s natural circadian rhythm and evening relaxation, helping promote healthy melatonin signaling, improved sleep quality, and refreshed daytime performance through a passive, non-electronic lens design. It is recommended that the proprietary ophthalmic sleep lenses are worn 2+ hours before going to sleep. They can be fabricated and sold in both a non-prescription or prescription form.
