Swanwick Cat Eye Day Teal Two Tone Regular Blue Light Blocking Glasses

• PREMIUM DAYTIME BLUE LIGHT BLOCKING GLASSES: The specialized virtually clear lenses in Day Swannies can block the most harmful part of blue light (98% at 400nm, graduating to 47% at 450nm), reducing electronic screen glare but still allowing some good blue light in to help regulate the circadian rhythm and support mental alertness during the day.
• STAY PRODUCTIVE WITHOUT THE DIGITAL EYE STRAIN: More than just a stylish fit, Day Swannies are exclusively designed to help you avoid digital eye strain and its detrimental effects, including sore eyes, headaches, dry eyes and blurred vision.
• A PRACTICAL GIFT FOR PROFESSIONALS AND STUDENTS: Give the gift of visual comfort with a pair of Swannies to help protect your loved ones from the glare of their laptop screen, smartphone or gaming PC, especially when they work (or play) all day.
• PAIRS PERFECTLY WITH OUR NIGHT SWANNIES: Day Swannies are designed more for digital eye strain protection than for sleep support, so we recommend switching to Night Swannies which can block the full spectrum of blue light to help you optimize your sleep/wake cycle and get a great nights sleep.
• The majority of adults find that the regular size is the best fit for them. Compare the measurements to your current eyewear. The lens, bridge and temple widths are usually marked on the inside arm of the glasses. Acetate frames can be heated up and molded for the perfect custom fit, or adjusted if bent out of shape. Most opticians or eyewear stores will do this for free.

FLATTERING ON ALL FACE SHAPES, THIS BLUE LIGHT BLOCKER IS HIGH-CHEEKBONE VINTAGE AT ITS FINEST.
Swanwick's Cat Eye Day Swannies are like walking off the set of Breakfast at Tiffany's.
With the unmistakable Swannies finish, these retro blue blockers bring a classic feline flair and don't skimp on anything for style.
Swannies are the blue light blocking glasses that actually work.
Youll find most clear-lens blue blockers on the market only block blue light up to 420nm.
Day Swannies lens technology, however, blocks 98% of blue light at 400 nanometers, graduating to 45% at 450nm, and 21-45% of blue light between 450-500nm.
This proprietary blend of blue light blocking provides you the optimal conditions for peak performance all day long.

Why are Day Swannies clear?
The almost-clear lens is for daytime screen-time.
They block the blue 400-450nm wavelength range, shown to be most harmful of the spectrum, while allowing healthy light.
