Superior Blue Light Blocking Day Lenses In Our Beautifully Crafted Crystal Frames.

Crystal Day Swannies - LAST CHANCE has a rating of 4.8 stars based on 40 reviews.
Swanwick's Crystal Day Swannies are tough to beat on the fashion front! Originally launched on Indiegogo, these Day Swannies remain at the top of our bestsellers list month after month. You'll block the bad blue light from phones, tablets, and computers while attracting compliments like never before. You’ll find most clear-lens blue blockers on the market only block blue light up to 420nm. Day Swannies, however, block 98% of blue light at 400 nanometers, graduating to 45% at 450nm, and 21-45% of blue light between 450-500nm. This blend of blue light blocking ensures you the optimal conditions for performing your best all day long.

Hear it from the experts.

If you want to use your iPad, mobile phone or watch TV at night before bed, that turn off your brain’s ability to produce melatonin. Swannies [blue light glasses] filter out that blue light so that you don’t have to give up your devices.

The Swannies blue glasses improved both sleep and work outcomes.

I’m a believer in how Swannies blue light blocking glasses affect sleep onset and duration of sleep because we see it all the time with our patients and our athletes.

Another brand that’s highly rated is Swanwick, known for blocking blue light exposure.

Swannies [blue light glasses] scored consistently well in all aspects that we tested. They have managed to combine effectiveness at filtering sleep-disturbing blue light while also allowing in non-sleep disrupting light, striking the right balance of sleep benefits.
