Eyekepper Classic Sleeping Glasses with Blue & Green Light Blocking, Red Lens Night Time Eyeglasses for Optimized Sleep Red

DescriptionBASIC FUNCTION"Sleep glasses", also called blue light blocking glasses, are made to be worn in the evening. They filter out blue and green light from screens that can mess up sleep patterns. WORKING PRINCIPLE1. Blocking LightThey block short - wavelength light in the 400nm to 550nm range, which is often called the "melatonin disruption zone". 2. Supporting Hormone ProductionBy cutting down on exposure to blue light from screens, they help keep the body's natural production of melatonin (the sleep - regulating hormone) going. 3. Improving Sleep QualityUsing them regularly may help you fall asleep faster, wake up less during the night, and feel more refreshed in the morning.

USAGE TIMEWear them in the evening, usually 2 - 3 hours before going to bed. USAGE SCENARIOUse them when you're around artificial light from devices like computers, phones, and tablets. POTENTIAL ISSUESThe amber or red lenses can change how you see colors, making it hard to see some colors correctly. Also, don't wear them while sleeping as it can be uncomfortable and may damage the glasses.
