The Tangle with Rhythm500 lens

Sale price Price $119.95AUD Regular price

Meet The Tangle.

Don't be a square.  The thin rectangular frame of The Tangle look great on those with oval or round face shapes.

The Tangle's Rhythm500 lens protects your eyes from receiving 100% of the harmful blue light spectrum and filters the green light too. You are being bombarded by junk light from the screens of your smartphone, tablet, computer, and tv, not to mention LED and Fluorescent lighting...your biology was not designed for this!

By blocking out 100% of this harmful blue light and reducing the green 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

Great quality!

We can truly tell these glasses are great quality! very clear, comfortable, light and most of all effective! highly recommend these to everyone, great value for money!


I was in shock. Free shipping worldwide...
Super responsive company, I asked a lot of question on their Facebook Messenger and was answered politely. I asked them to double wrap the box and they did.
I give them 1000 on costumer experience.
For the glasses- I was skeptic of their Blue Blocking abilities so I did every online test that I found...They passed them all. I can't even see the blue dots that tell me the time on my cable company device.

If I would order another pair, I would order a longer frame pair so i can block more of the light.

10/10 would definitely BUY AGAIN!

Lightweight, comfortable

After trying various Blue Blockers over the years "The Tangle" by Rhythm Optics are now my go-to pair of blue blockers. Lightweight, comfortable, excellent build quality and come with a very nice hard case for storage. Customer service and communication from Rhythm Optics is excellent!

Healthy eyewear for after dark

I was very happy to receive my order so quickly and am very impressed with the packaging and the quality of the glasses. I've only been wearing them a few days so I can't comment on their effectiveness yet, but they certainly do block the blue and some green light when worn round the house after dark. I am looking forward to the sleep and health benefits from these glasses.

Best looking pair of blockers on the market

Love the Tangle Sundowns! 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 these for my wife since she looked so good in them too
