Experience light as nature intended
Blue light after sundown doesn't exist in nature and is alien to our biology. We are designed to see only amber-red light at night. That's why a campfire feels so good!
Restore your Circadian Rhythm
Our eyewear blocks out the specific wavelengths of light that supress Melatonin and cause circadian disruption. This will help you sleep deeper and wake refreshed.
Recharge your mitochondria
When your circadian rhythm is in sync, you optimize your mitochondrial function. You will literally have more energy and vitality, and more resistance to most modern diseases.
Block blue and green light after sundown for the best sleep you've had in years!
Our After Sundown eyewear collection allows you to still be exposed to artificial light from your screens and home lighting at night while protecting yourself from Circadian Rhythm disruption.
With 2 after sundown lens options you'll find the right one for you whether new to blue blocking or a hardcore biohacker!
The Rhythm500 lens is developed to block out 100% of artificial blue light and the Rhythm560 lens goes further to block out virtually all green light too.
Rhythm Optics are the solution to unavoidable modern light that causes melatonin suppression. In turn supporting deep restorative sleep and optimal mitochondrial function, the key to good health and disease prevention.
Filter blue light during the day to prevent digital eye strain & retinal cellular damage.
Our During Daytime eyewear collection of anti-blue light lens styles are for those spending long days behind computer, tablet, and mobile screens and while in artificially lit offices.
With clear or yellow tinted lens to choose from you'll find the right solution for you.
The RhythmCLR is a clear lens formulated to reduce blue light to prevent digital eye strain. Being crystal clear it doesn't distort colours - great for the office, they look smart and don't attract attention.
The Rhythm450 lens is specially developed for the serious screen user. Whether you're a hardcore gamer or just stuck behind a computer all day in a horribly lit office, you can block out the wavelengths known to cause cellular damage to the eye.
The Block features our Rhythm560 lens in a smooth matte black frame. Big and bold, it makes no apologies! Its larger frame style prevents light leak from top, sides and bottom. Made from TR90 it is ultra light yet strong and flexible.
The Rhythm560 lens protects your eyes from receiving the harmful blue light spectrum and filters out virtually all green light too.
The Rhythm560 lens is a full red lens developed for maximum melatonin preservation. These are for the most serious blue and green light blocking biohacker!
By blocking out blue light and green light right up to 99.64% at 560nm, you will avoid virtually all light that has the ability to suppress melatonin.
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!
I'm wearing these now as I write this review! My sleep has improved at least 75%. It takes a little getting used if you want to watch a show because the colors are muted however my sleep is worth it! I now start wearing the red glasses around 7pm and your eyes become so accustomed that you can't tolerate any bright light afterwards. Thank you for making such comfortable and productive glasses for our health.
Ok so i burnt out years ago, and smashed my hormonal system.to bits and one of the many things since I dont sleep well. So i thought i would try these and dead set cant believe how well they work. I dont want to ramble on but if i got on my phone at night i could stay awake until i ran out of things to look up, with these on i am out. But thats not the end, the quality of sleep is so much better, i remember my dreams again and my energy has gone through the roof.
If you have any of my issues just buy them....
This is a quality product. The square frames are nice and large. Fast delivery. For those that like detail it comes in a solid box for storage. I have recommend rhythm optics to friends. Worth the investment. I love them.
I just wanted to express my gratitude for your product. I have had insomnia for 18 months now, and every treatment I’ve tried hasn’t worked including thousands of dollars worth of supplements, herbs, cannabis, sleep hygiene, psychology, medication, meditation, ASMR - you name it, I’ve done it. Doctors and naturopaths have all been stumped. I put the glasses on at 8pm last night, laid down on the couch to wind down, and started to doze off (which was unusual for me). I went to bed to see if I could sleep - and I slept easily for 8 hours. I cannot thank you enough, this has instantly changed my quality of life. My endless thanks to you!
Thanks Rhythm Optics. Great product.
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
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!!!
It literally how it said. No blue light or green light. My eyes arent sore anymore. So good!. I was trying to drive with the glasses on guess what? I did not see the green color lights its that great! Highly recommend it.
Great product and fastest delivery.
Great glasses, love them! Super fast shipping as well👍
I live in England, and couldn’t find a quality pair of light blocking glasses anywhere, I was recommended this brand, and I’m so pleased I brought from this company. I have two pairs, one to wear from sunset onwards, then these red ones that block out nearly all blue and green light. The duo works a treat, and now I sleep soundly. My Fitbit shows a sleep score in the 90’s, were before it was in the early 60’s. I’m now a morning bird and not a night owl. I feel much more alert and fresh everyday. A must for anyone who what’s to look after their health
I have struggled with sleep for the last 6 years, I have tried everything I can from prebotics, acupressure mats, chiro, basically anything that says 'will improve sleep' and while my health has improved I still struggle with sleep. I wake up through the night and can be awake for hours. I bought the glasses not expecting to see any results as I use night mode on all devices but since getting the glasses from the first night I slept amazingly! My REM has gone from 1.5hrs'ish to 2.5hrs'ish a night and I feel very switched on during the day!
The glasses are comfortable, look good on and are good quality. Thank you for changing my world!
I definitely recommend these glasses. I throw them on a couple hours before bed and feel my eyes getting drowsy shortly thereafter. This is a change from before as I have not usually experienced such a relaxation response in my eyes prior to bed. Excited to see how much this improves my well-being in the long run! :)
