Non invasive prevention and treatment for Diabetic Retinopathy & Diabetic Macular Oedema
Discover the Noctura 400 Sleep Mask
The Noctura 400 Sleep Mask from PolyPhotonix is a revolutionary treatment for diabetic retinopathy and diabetic macular oedema (DMO). See the steps below or click the play icon to watch the video and learn what effect retinopathy has on the eye and how non invasive treatment can help.
- When you have diabetes, high blood glucose levels and circulation problems can cause changes to the blood vessels in the eyes and lead to diabetic retinopathy
- When it is dark and you are asleep, the eyes need more oxygen
- In the diabetic eye the retina can become starved of oxygen
- The eye tries to produce new blood vessels to deliver more oxygen to the retina
- These new blood vessels are often weak, leak fluid and blood, which affects vision and could lead to total sight loss if left untreated
- The Noctura 400 Sleep Mask is an innovative technology, which can be used as a therapy for diabetic retinopathy and diabetic macular oedema
- The mask administers a precise low-level light through closed eyelids while you sleep, to reduce oxygen demand

My Noctura Story
“I have finally been discharged by the hospital… I personally believe there is a direct connection and that the Noctura 400 eyemask has helped in preventing my eye condition worsening.”
UPDATE! January 2016
I have been attending hospital and having increasingly regular laser treatment for retinopathy over the last 4 years. Having had no need for laser since November 2014, I have finally been discharged by the hospital. This last year without laser treatment coincides with my using the Noctura eyemask. I have been using this for 11 months now and I personally believe there is a direct connection and that the Noctura 400 eyemask has helped in preventing my eye condition worsening. I will keep using the eyemask as I feel it will continue to keep my eyes healthy.
Four years ago, I was told I had Diabetic Retinopathy (DR). It’s obviously scary when you find out you have a condition which could cause you to go blind. The worst thought for me was the fear I could lose my peripheral vision and not be able to drive. I work as an architectural technician for Durham County Council so I wouldn’t be able to do my job if I lost my sight.
For three-and-a-half years, I’ve had more laser treatments than I could count. It was pretty much every month. The more laser treatment you have, the more sensitive your eyes become so the more painful it is. Then afterwards, I used to get bad headaches.
I went to a seminar about the Noctura 400 eye mask and signed up straight away. I’m now on my fourth mask. Since I started wearing it, I’ve had no laser treatment at all. It’s really given me hope for the future as before I started wearing the sleep mask, my eyes seemed to be deteriorating quickly.
I was diagnosed with Type 1 Diabetes in 1984 when I was 10. I’d lost a massive amount of weight in a week. My grandad was diabetic so he had an idea of what it was. The regime you have to keep to has changed a lot since then. I used to have two injections a day but now it’s five or six, which gives you more freedom when it comes to meals. That’s part of an education programme, which helps with control but until I found out about the sleep mask, I didn’t think there was a great deal I could do to stop the retinopathy from getting worse.
The light from the sleep mask isn’t bright at all, so it doesn’t bother me and I can see when I go to the opticians what a difference it is making. They show me pictures of my eyes each time and I can see that my condition is now stable.
“I’m no longer worried about losing my driving licence, no longer worried about losing my house or my job.” NEW: Updated testimonial!
UPDATE! – March 2016
My last eye checkup at the hospital in January confirmed that for the first time in over 2 years, BOTH my retinas are stable once again…with no signs of any small bleeds at all; hospital is well happy with the progress from the mask…as am I!
I was diagnosed with diabetes at the age of 18, and have been taking insulin for the past 32 years now. I hope to still be on insulin and taking care of my diabetes in another 30 years time too, so am always keen to find ways of improving my glucose control. Diabetes Type 1 is where your pancreas stops producing insulin, a hormone that takes sugars out of your blood. So diabetes care is about keeping my blood sugars controlled as much as I can, without my own natural insulin that most people have to do this automatically; hence the need to inject with insulin. Being an active person enjoying heavy gardening and digging on my allotment and looking after animals, I have been fortunate to have not had major complications until recently. 3 years ago damage to my retina was discovered at my annual diabetes eye screening. The blood vessels in the back of our eyes are the smallest in the body, and with higher sugar levels they can get blocked, and so new weak vessels grow to get around the blockage in your retina. These weak new vessels can then bleed into the back of your eye, and of course, this affects your vision.
I drive 100 miles a day to get to work, so am very concerned about keeping my driving licence as I feared losing my job if I cannot commute by car. I received over a dozen sessions of laser therapy at the eye hospital, but new bleeds kept on occurring every month whenever I did something strenuous like digging.
I then started to use the Noctura 400 sleep mask in October 2014 and immediately I found an improvement, in that in the first 6 months of wearing the mask every night I did not have a single further retinal bleed. I have now been using the Noctura 400 for a year; before the mask I had 12 new retinal bleeds in one year; since wearing the mask at night I have only had one small retinal bleed all year and only go to the eye hospital every 3 months now for a check-up.
I would recommend anyone with retinal damage to consider its use, along with your eye specialist, as without the Noctura 400, I fear I may have already lost my driving licence, and here I am commuting in my car, working hard and enjoying a full life without the fear of my eyesight getting worse.
NEW: Watch Sue’s story after 12 months of using Noctura 400:
You can also listen to Sue’s story after 6 months of using Noctura 400 in the video below.
I have been a type-1 diabetic for 50 years and was very interested when I heard about the light-based therapy being developed by PolyPhotonix. In recent years I have received laser treatment for diabetic retinopathy in each eye and this has always been a source of concern, particularly as it can potentially lead to the loss of my driving licence. The fact that the light-therapy from PolyPhotonix is non-invasive removes this cause for concern which is fantastic as the risk of losing my licence is no longer an issue.
I live in the country and need to drive around 30 miles to get to my job as a higher level teaching assistant in a school. If I lost my licence, my husband and I would have to move house and substantially change our lifestyle. I am also a member of Girlguiding UK and being able to drive to the units I support is very important to me, not to mention the independence that being able to drive brings.
The day before I started wearing the mask, I had undergone a routine eye examination as part of the continuing support I get as a diabetic patient. After a couple of weeks, I got a letter from the department that had carried out the examination, indicating that the image showed a potential macular issue and referred me for a more detailed examination at the local eye hospital, for an appointment with a consultant. This took place around six weeks after the initial examination, during which time I wore the PolyPhotonix mask when going to bed. I would definitely recommend other people with diabetes to use the mask as at this second consultation the doctor could see no evidence of any macular issue proving to me that the Noctura 400 mask had cleared up any macular issues. I had done nothing differently over the six weeks between consultations except from wearing the mask when going to bed.
For the first couple of nights of wearing the mask I was aware that I was wearing something however, it was absolutely fine. If anything, I would go as far as to say that I sleep better with the mask on, I have not had a sleepless night whilst wearing the mask. The light levels are easy to sleep through and even if you were to open your eyes and look at the lights they are of a comfortable level to look at. I have had to make a minor adjustment to my head position whilst sleeping however it has caused me no problems. The fabric mask has caused no reactions with my skin which is brilliant as I have very sensitive skin so there was always a possibility of this happening.
The mask is easy to use and understand with very easy to read instructions for use making it simple to use at home. Once I had used it for a number of nights it just became routine to put the mask on when I was going to bed.
Over the years, I have had laser treatment in both eyes for retinopathy which solved the problem in 2000/2001, however at my check-up in early 2014 the retinopathy had worsened again. There is no contest that I would choose the Noctura 400 treatment over the laser treatment. The non-invasiveness and easy to use nature of the mask removes any traumatic experiences that occurred when having my eyes lasered. I continue to wear the mask when going to bed and would encourage anyone with diabetes and suffering from retinopathy to do the same.
“My eye specialist has already said he has noticed an improvement.”
I was diagnosed with Type 1 diabetes on August 14 1972 at 11am. I was 14 at the time. It was a painful time in my life and it is indelibly etched on my mind.
We’d been to Disneyland California and I pretty much ruined the holiday. I could tell you what every toilet looks like in Disneyland. It came to a head when we went on lion safari. You go in your own car and it takes two hours, but we were in there for ten minutes because I needed to go to the bathroom again.
My parents took me to the doctor as soon as we got back home. I went into A&E where I was given insulin, and I felt better pretty much immediately.
I was living in the US at the time and you spend around two weeks in hospital doing diabetes education sessions before you are discharged. That stood me in good stead for years to come.
Back in those days, diabetes care was very different. You had a very rigid routine where you had to do the same thing at the same time every day. You ate the same food every day and your portions were measured.
Things moved on in the early 80s when you got two insulin injections a day. Now I have multiple injections and I’m due to move to an insulin pump.
Having diabetes is a tough old road to run along but the toughest thing is the effect it has on my wife Diane. She worries so much about me, but I’m pretty good at looking after myself. You just try to do the best for your health that you can every day.
But no matter how much you look after your own health, you can’t avoid some of the complications that come with diabetes. Being told you have diabetic retinopathy and that it could lead to you losing your sight is scary because it would mean losing a big part of your freedom.
I’m retired now so it’s not about work, but I like gardening, my wife and I go for day trips, music is a big thing for me. Not being able to go out and the thought of my wife having to care for me would be awful.
I’d been attending an ophthalmology clinic since around 1990 and nothing much changed until 2002 when I had laser surgery. I had more laser in 2012 and when my eyes started to deteriorate, I also had injections into my eye in 2013, which was the most horrendous thing I have ever gone through. I’ve broken my shoulder, I’ve had my wisdom teeth removed and the injections were far worse in terms of the anticipation, what happened during the procedure, and the pain, which felt like my eye was on fire.
I found out about the Noctura 400 sleep mask quite by chance by reading an article about it. When I called makers PolyPhotonix to ask about it, I was invited to an information evening. I now get a new mask from my optician Lyndon Taylor every three months so my condition can be monitored.
My eye specialist has already said he has noticed an improvement. But, even if it doesn’t noticeably improve my condition, it should in theory keep it at where it is now. To have this alternative, which could stop further eye damage is a huge relief.
“I’ve noticed I can now read labels and price tags when I’m out shopping.”
I was first diagnosed with Type 1 Diabetes around 25 years ago. I had lost a lot of weight and I could have drunk the seas dry, so I recognised what the symptoms were. It is the lifestyle changes that get to you, particularly as my three children were young at the time and I was working as a childminder.
I had to have four or five insulin injections a day and you have to eat at certain times of the day. I was pretty good at spotting the symptoms if my blood sugar levels were low. You have to make sure you’re looking after yourself when you’re looking after children. I do pilates and zumba and I walk a lot, so I try to make sure I’m doing the right things.
I developed Diabetic Retinopathy 15 years ago. At that point, I’d had a career change and was working as a florist. I was reaching up to get some flowers so I could put a bouquet together when blood suddenly burst up inside my right eye. It’s rare to actually be able to see a bleed so it was terrifying.
I had so many laser treatments to try to control the condition that I lost count. They were damaging my eyeballs to try to save my eyesight. The treatment has moved on but when I first started having it, the laser felt pretty hot. It’s not a pleasant experience.
I can’t drive anymore because of poor peripheral vision and I had to give up work because I was disorientated when using the phone, till and card machines.
I really did wonder if I would lose my sight completely. I have three children and my fifth grandchild Beatrix arrived a few weeks ago. Not being able to see my grandchildren was my worst fear. I also like reading, although I’ve had to buy a Kindle because of the small print in most books. I can’t see certain shades and tones like yellows and sometimes I can’t see the weeds until they get fairly big, but I still love gardening.
I read about the Noctura 400 in an article and contacted the makers. I get the mask through Wade Opticians and I’ve been using it for nine months. I don’t notice the glow at all while I’m wearing it.
I hoped the sleep mask would stabilise my condition. I didn’t expect I would have improvements, but I have. The biggest improvements came within the first three months. Since I started to wear the sleep mask, I’ve had no further laser treatment and no further bleeds. I’ve noticed I can now read labels and price tags when I’m out shopping, which I’d never have been able to do a few months ago.
“I just wish I’d known about the mask earlier before the damage to my eyes happened.”
I was diagnosed with Type 1 diabetes when I was 12 and was told five years ago during a routine eye examination that I had developed eye disease.
It’s terrifying to be told you have retinopathy. A million scary thoughts go through your head about losing your sight. I’m only 40 and I have children; Libby, 11, Jake, 14 and Connor, 16. I want to be able to see them grow up; to see their wedding days.
I was diagnosed with diabetes after displaying the classic symptoms of needing to visit the bathroom more often and I had a raging thirst.
I would buy drinks from other pupils in the playground for extortionate amounts because I was so thirsty. I was tired and had no inclination to go out. It was coming up to a school trip and my mum took me to the doctors as I’d been under the weather. I ended up being in hospital for two weeks learning all about diabetes control.
There’s always an awareness there but I still do everything everyone else does. If you never had a drink or a burger, life would be pretty boring.
A check-up picked up some issues at the back of my eyes when I was 35. Since then I’ve had several bleeds in my eyes and at least five laser treatments. Every time I went back, I was told I needed more surgery.
It’s not pleasant. The first time isn’t too bad but once you have scaring from previous treatments, it becomes very painful. The laser treatment is designed to stop the bleeds, but it also burns off part of the retina and, if they make a tiny mistake, you could lose your sight.
I wasn’t happy about the amount of laser surgery and I ended up being transferred to Moorfields Eye Hospital. After doing some research, I made the decision to use the Noctura 400 mask.
After three months, my consultant at Moorfields said he’d seen a regression. There’s been no new growth and I haven’t had to have any more laser treatments.
I enjoy motorcycling as a hobby and I drive for work as a roofing manager, so you worry about your livelihood. I want to see my three kids grow up, live their lives and get married.
When I was first diagnosed with retinopathy, it was very much doom and gloom. No one could tell me that I would definitely still be able to see my children in 10 years’ time. Now, I finally feel hopeful again. I just wish I’d known about the mask earlier before the damage to my eyes happened.
I was fit as a butcher’s dog when I was diagnosed with diabetes 45 years ago. I played football and county level squash. I had lost a bit of weight for no reason and I had an excessive thirst. I was an HGV driver and I used to drink bottles and bottles of lemonade every day.
Once I was diagnosed, I was in hospital for two weeks to make sure my condition was stabilised and I knew how to manage it.
Since then, I’ve gone religiously to diabetes clinics. I take my blood sugar twice a day and, at the moment, it’s pretty good as it’s in single figures. You live by mealtimes and have to eat decent food at regular intervals. I do my exercises religiously for what is left of my legs and springs and weights for my upper body.
I now rely on a wheelchair after losing both legs because of diabetes. I lost my left leg eight years ago below the knee and, then two-and-a-half years ago, they operated on the right leg, amputating above the knee because of poor circulation in my toes.
I’m in a wheelchair but I do have a prosthetic left leg and I’m going to have a right leg fitted too, so I am hoping I will walk again. The more difficult it is for me to get around, the harder it is for my wife Mabel.
Losing your legs obviously does hit you hard but I think the toughest thing for me was losing my driving license because of poor peripheral vision.
I’ve lost count of the number of laser treatments I’ve had. Every time you have laser treatment, it causes scaring. There are so many white scars on my left eyeball, it looks like a golf ball, although my right eye isn’t as bad.
I hope the sleep mask can stop any further damage. Diabetes ruins your life. It has already taken my legs and I don’t want it to take my eyes as well.
“But, I was already doing everything right. I have a good diet, I walk 20 miles a week and I check my blood sugar.”
I already have hearing loss as a result of diabetes so there were worries about losing sight as well.
The sleep mask gave me hope at a very bad time. I had worried out losing vision and not being able to drive or even read a book. You naturally have fears about that loss of freedom.
Since starting to wear the sleep mask, my optician has noticed that both eyes have improved. It’s given me hope that the deterioration in my eyes has been arrested.
I was first diagnosed with Type 1 diabetes 30 years ago. I had been feeling very unwell. I was a nurse, so I knew exactly what it was, but I just didn’t want to hear the diagnosis.
When I was first diagnosed, I had to inject insulin morning and night, along with eating carbohydrates at a certain time of day. I now have an insulin pen, which has given me much more freedom.
I’m already dependent on hearing aids as a result of diabetes. I was diagnosed with Diabetic Retinopathy five years ago. My consultants said that if my eye condition did worsen, the damage already done was too close to the optic nerve, so they would only inject if they really had to.
I’ve since had laser treatment and injections in the right eye, but nothing at all in the left, other than the mask. I’ve been told there has been improvement in the left, which has given me hope that the sleep mask is working.
When you go for check-ups as a diabetic, you’re told to improve your lifestyle to improve your control of the condition and stop it deteriorating. But, I was already doing everything right. I have a good diet, I walk 20 miles a week and I check my blood sugar.
My fear was that I was already doing everything I could to help myself and my eyes were still getting worse. To have this preventative treatment, which could stop further eye damage, is a huge relief.
More than just a mask
The treatment is part of an ongoing monitored therapy and regular check-ups are provided.
At the end of a 12 week period, the mask is returned for analysis and a replacement mask is provided. The collected usage data allows the clinician to compare the patient’s usage of the mask with changes in vision.
