"My daughter recommended me these blue light glasses as I was getting sore eyes in the evening. They have been helping, but I find it hard for my eyes to adjust to the red lenses (sleep lenses). Maybe I should have opted for the relief or screen + lenses to begin the adjustment on my eyes. I personally would suggest to anyone who just wants to help with relief on eye strain to go with the clear or orange lenses. If you struggle with sleep I've been told these (red lenses) are better for late into the evening before bed (advice from my daughter). Overall great quality, and nice add ones in the box. Cloth, cork case, cotton pouch etc. Worth the money."

Review

"I've been using the Dougo's Relief Glasses with the new Wunsch frames and I have to say that I couldn't be happier. I've tried blue light glasses from other brands before and I wasn't impressed. The frames were ok, but the lens just didn't cut it for my needs. This isn't the case with Dougos. When they arrived 2 weeks ago, I could tell they were different the moment I put them on. I sit on the screen from 7am to around 4pm most days, so I often feel eye strain and dry eyes from looking at the screen. By the end of the day, I always experience heavy brain fog which limits my performance and thinking — the last few hours of my workday are limited to menial tasks being dragged-out far longer than they should take. Not anymore. With Dougos, my eyes feel significantly better — not like I've been burning a hole in them for hours. And my mental performance at the end of the day feels like it's on another level. My colleagues say I'm more lively and active during meetings, and I'm finally getting stuff done after 2pm. Sure, I still get a little tired and sluggish — that's normal. But it's a HUGE improvement from before. I never realised how much a properly configured blue light lens can help. And to top it off, they look great. I highly recommend Dougo's if you're looking for a pair of high-quality, effective blue-light glasses."

Blue light exposure could be making you fat, sick and tired.

Wake up exhausted? Can't switch off? Exposure to unnatural blue light triggers a hormonal imbalance that can result in various health complications. The good news: you can fix the light you are exposed to.

52%

reduction in melatonin after using digital devices in the evening.

Experience sleep as it should be, restorative and refreshing. Our filter technology is designed to transform toxic light into healthy light. Don't let poor sleep catch up on you.

WHY IS MELATONIN IMPORTANT?

Exposure to artificial light at night hinders our melatonin production. This sleep hormone, known for its regenerative properties, also reduces stress and recharges cell energy.

Got a question? These usually clear things up.

Frequently asked questions

What actually is blue light?

Blue light is a section of the visible light spectrum within 380nm - 500nm. It has shorter wavelengths than other visible light and is thus easily scattered. When blue light hits the retina, a significant amount of energy is absorbed, leading to digital eye strain, headaches and sleep apnea.

Blue light in the morning isn't so much an issue as it stimulates cortisol production to keep us alert. 

However, in a world where night turns to day with the flick of a switch with LED’s, we have a big problem: Too much blue light can be harmful. It is vital to strike a balance in our exposure to blue light and to take steps to protect our health from its damaging effects.

How is artificial light destroying my health?

Artificial lighting such as LED's (screens, headlights, lamps, downlights etc.) emit high amounts of isolated blue light. (See 'What is blue light?' above).

Modern light emittance peaks 440nm, with device lighting at 455nm. Melanopsin is most sensitive at 430-45nm and triggers a daytime response in the endocrine system (hormonal system).

This means that our circadian rhythm becomes disrupted. In addition, the lack of UVA/B and near-infrared light (which we only get from the sun) means the cell regeneration response becomes blunted, meaning ocular cell death that can lead to visual problems.

What is a circadian rhythm?

Circadian rhythms are the natural daily fluctuations in biochemical, physiological, and behavioural processes that occur in living organisms. These rhythms follow a roughly 24-hour cycle and are driven by an internal biological clock.

The term “circadian” comes from the Latin words for “around” (circa) and “day” (diem). Circadian rhythms are found in most living things, from bacteria and plants to animals.

In humans, circadian rhythms play a role in many aspects of our physiology and behaviour, including sleep-wake cycles, hormone release, body temperature fluctuations, and metabolism.

Circadian rhythms are essential for our health. Disruptions to our natural sleep-wake cycle can lead to sleep disorders and have been linked to obesity, diabetes, depression, and other health problems.

Exposure to artificial light at night can disrupt our circadian rhythms and lead to sleep problems. To promote good sleep and protect our health, limiting our exposure to artificial light in the evening and sleeping in complete darkness is essential.

How are your filters different to competitors?

Our lenses are designed and manufactured by leading specialists in the UK, packed full of technology you won’t find anywhere else. Each pair of lenses goes through a 20 stage process to ensure you are protected from harmful HEV light.

Here are a handful of features our lenses boast:

- Anti-reflective coating

- Anti-static coating (prevents dust) 

- Anti hydrophobic coating (prevents water)

- ‘Green coating’ is made by nine layers of treatment applied to the lens, meaning clearer images without glare and a longer period without eye strain. 

- CR39 lens as standard

Why is melatonin critical for good health?

Melatonin is a hormone that is produced by the pineal gland in the brain. It is best known for its role in regulating sleep patterns, allowing us to drift off and stay asleep, but melatonin also has important immune system benefits. 

There are a few ways in which melatonin can help to boost immunity. Firstly, it can help increase the production of specific immune cells, such as natural killer cells and cytokines. These cells play a vital role in fighting off infection and helping the body heal. 

Secondly, melatonin has been shown to have anti-inflammatory effects. Chronic inflammation can weaken the immune system and make it more susceptible to disease. Finally, melatonin can help to protect the body from oxidative stress. This condition is caused by an imbalance of free radicals and antioxidants in the body, which can damage cells and lead to inflammation.
