The Tangle Day by Rhythm Optics
Meet The Tangle.
Don't be a square. The thin rectangular frame of The Tangle looks great on those with oval or round face shapes.
The Tangle Day protects your eyes from receiving artificial blue light thanks to our Rhythm450 lens technology.
This "yellow" lens filters out all but 1.2% of blue light at 440nm. At 450nm it is 1.3%, at 460nm it is 6.7% and at 470nm begins to allow more in at 41.8% and progresses up from there.
Enough to reduce digital eye strain and also allow you to taper down your light intake over the afternoon, setting you up for an ideal evening of rest. You don't still want your eyes to be receiving "solar noon" signals from your screen at 5pm!
By blocking out this harmful blue light, your light environment will be more like nature intended. Your circadian rhythm will be optimized. You will sleep better at night, wake at the right time in the morning, and have more energy and mental clarity throughout the day. Ultimately you reduce the effects of ageing by supporting your mitochondrial health, which is key to prevention of most modern diseases.
Frame Size: 50mm wide lens - 19mm wide bridge - 140mm long temple
Love the Tangle Day! Don't think there's a better looking pair of blockers on the market. I purchased the Tangle in both the Day and Sundown tint and within 2 days I was falling asleep faster and easier than I have in a long time. The look of the Tangle would look great on most any face, man or woman. and I just bought the Sundown for my wife since she looked so good in them too.
