For over six years, Swanwick® has researched and developed the best lenses for blue light protection, sleep enhancement and wearing experience.
Night Swannies blue light blocking glasses are the most scientifically-backed blue light blockers, independently proven to positively impact sleep quality and next-day performance by blocking over 99% of blue light waves from entering your eyes.
Once you’re asleep, the blue light you were exposed to before bed can continue to wreak havoc on your sleeping pattern. Get deeper and more restful sleep by using Night Swannies blue light blocking glasses continuously before bedtime.
Most clear lens blue blockers block very little blue light over 420nm. Day Swannies block more blue light in the harmful part of the spectrum up to and over 450nm. Our full transmission reports are available on our website.
Give your natural body clock the right signals to get ready for sleep. With these proper signals, your body will produce its own melatonin, the sleep-promoting hormone, just like nature intended.
Prescription grade CR-39 lenses are combined with special blue light reflecting coatings to block the right amount of blue light for day or night use, all while providing superior optical clarity.
Digital screens create glare and light flicker which make your eyes work harder, causing a feeling of fatigue and strain after prolonged periods. Swannies lenses protect your eyes from these negative effects, helping you work longer without consequences.
