Do you ever struggle to fall asleep and can’t figure out why? Or perhaps you wake up in the middle of the night for what seems to be no apparent reason? It’s likely that blue light from your phone, TV or tablet is disrupting your circadian rhythm, (i.e. the part of the brain telling you when you should be sleeping or awake.)BluTech Lenses can be worn throughout the day to help relieve digital eyestrain, but clinical tests have shown that by wearing them at least three hours before bed, you can shield your eyes from the high energy, short-wavelength light (blue light) that alters your sleep/wake behavior. Ultimately, BluTech Lenses can increase your melatonin levels, resulting in a good night’s rest, improved sleep, health and productivity.
