Use our Nighttime Glasses if you are serious about taking back your sleep schedule and making your sleep more restful. These amber-tinted blue light blocking lenses are made to shield you the MOST from disruptive light that reduces the production of melatonin, which affects your body's natural sleep-cycle. Swap out your clear daytime glasses in the evening to nighttime amber lenses and allow your body to produce the melatonin it needs for a restful night of sleep, or use it for when you drive at night to help reduce the glare of oncoming traffic. With up to 90% blue-light filtering (more than BluDefend, our daytime clear blue light blocking lenses), these lenses give you the near-total protection from blue light to take back your sleep and regain your zzz's. Available in prescription, non-prescription, and reading lenses, try a pair of our Nighttime glasses from LensDirect today!
