Why Amber? With Blue Blocker Glasses, there are clear Lenses and Amber ones. But what’s the difference? Clear blue light blocking glasses only block up to 20% of blue light, while our Dark Amber glasses block over 99%! So, if you want to actually block blue light, Go Amber! | 99% Dark Amber Tint: For a Good Night's Sleep. Nighttime entertainment should relax us, but the blue light of laptops, phones, TV’s and lighting around our home inhibits organic melatonin production and elevates cortisol. Now, when you wear our Element LUX blue blocker glasses at night, you can enjoy entertainment AND a good night's sleep! | Love your Eyes!: UV400 Coating protects your eyes from all harmful UV Rays(A, B, and C). Our high quality amber orange lenses protect you from Blue Light spectrum rays (400-500nm). With our blue light filter glasses you can experience more Eyestrain Relief and Better Sleep. | Style and Comfort: For those of us who need uncompromised bluelight protection, our Element Lux Aviator Lenses offer Full Eye coverage, while other blue blocking glasses allow blue light to enter around the lenses! The sleek and durable TR90 frames along with our top quality Amber lenses are the perfect balance of Protection, Style, and Comfort. | With Case and Free Sleep Guide: You, like us, care about proper sleep and your health, so you also get a free sleep guide to help you get the best rest!

So if you’re ready to take back your sleep without sacrificing your screen time, you know what to do!
