The St. Croix Topaz Sleep Glasses complete what the daytime Computer Glasses begin. Where the daytime version manages screen-driven blue light load during working hours, the Sleep Glasses take over at sunset — CR39 orange lenses blocking 100% of disruptive blue light wavelengths to protect melatonin production and guide your body toward deep, restorative rest. Housed in the same lightweight TR90 frames with the earthy blue-gold topaz tones inspired by the St. Croix River, these bring a grounded, nature-connected aesthetic to the most important biological transition of your day. Wear them through the evening. Let the river do the rest.
