The Tangle with Rhythm450 lens

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.

Made of Swiss developed TR90 this frame is lightweight, durable and flexible. The inherent flexibility allows them to form to your face for improved comfort. Unlike cheap, brittle Polycarbonate frames, they wont easily break if sat on, stood on or dropped.

The Tangle Day features our Rhythm450 lens which is optimized for use during the day.  Perfect for long days behind a blue light computer screen in an LED or Flouro lit office.

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

Excellent daytime glasses.

I bought both pairs and they together have changed my life and sleep schedule. I no longer have insomnia. Amazing. I was also impressed with tje whole packaging of the products. Nice glass cases, cleaning cloths and soft carry bags. The amount of detail and care that has gone into this product is evident and I felt that upon opening my box. These are made by someone who really cares about our health and wellbeing. I am happy to support a company with these values. Thank you!

Does the job well

The Rhythm 450 lens has without a doubt alleviated my eye strains sitting in front of the PC for 8 hours a day at work. This was my key reason on purchasing it due to its high % blocking in the 450nm wave lengths.
It has lived up to its reputation and I would recommend it to people like me who has to stare in front of the PC for the whole day time. However, it is yellow lens, and people have looked at me strangely, so if image is really important in your workplace, then you may need to consider something else

Phenomenal glasses!

My husband works very long hours on the computer and his eyes get very achy and tired by the end of his work day. We decided to buy these blue light glasses after reading all the informational details and research that has been put into them on this website. We have received them and my husband noticed a difference RIGHT AWAY! They work wonders! His eyes are now feeling much better and he barely feels like he’s been sitting in front of the computer all day. It’s been a few days now and the great result hasn’t changed. We are beyond thankful for rhythm optics for selling such an amazing product! Thank you for saving my husband’s eyesight!!!

Couldn't ask for a better looking pair of blockers

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.
