• EXPERIENCE COPPER HD: Increase Clarity. Increase Contrast. See Farther. Copper HD sunglasses were made popular by golfers to help them see the ball after a long drive. proSPORT copper HD lenses filter out blue light in the UV spectrum which cause haziness; leaving a clearer and crisper view.
• WHY FILTER BLUE LIGHT?: Blue light exposure increases the risk of macular degeneration. Blue light penetrates all the way to the retina (the inner lining of the back of the eye) and can potentially damage the light-sensitive cells in the retina. Too much blue light exposure right before bed can cause insomnia.
• NICKEL SILVER FRAMES: For added durability and pliability, these sunglass frames are constructed of Nickel Silver. Nickel Silver is more rigid and possesses an attractive shine.
• WHY DOES BLOCKING BLUE LIGHT HELP YOU SLEEP BETTER? According to Harvard Medical School, artificial blue light emitted at night from LEDs, computers, phones & tablets inhibit melatonin production, the hormone that tells your body it's time to sleep. Without melatonin, your body's biological clock, the circadian rhythm, believes its daytime & NOT night time. The result: insomnia & disrupted sleep. Blue light boosts alertness & mood; so it's a good idea to block out blue light before bedtime.
• HOW DO BLUE BLOCKERS GLASSES WORK? Visible light includes the purples, blues, greens, yellows, oranges, and reds. Our orange Blu Blocking lenses specifically filter out blue light in the electromagnetic spectrum. Other colors, including 100% ultraviolet rays, are also filtered but not as much (if all colors were filtered, then you wouldn't be able to see!) Studies at Harvard Medical School and University of Toronto have shown that blocking out blue light promotes better sleep & mood.
