What our customers are saying

We're really proud the results that Noctura 400 has delivered for people.
 Here are just a few of our happy customers.
"From the scan results the little swellings which are the macular oedema have virtually disappeared."
Nancy Savage
"I noticed an improvement in my eyesight straight away. That was in 2019 and I have been using it ever since."
Michelangelo Biasiucci
"My eye doctor follows me every 3-4 months and while I have needed rare treatment with injections, I have gone 12-24 months in between any treatments. This has been fantastic news as I have avoided any serious progression of retinopathy."
Jacob Chojnacki
I’m a gardener by profession, so the mask has meant that I can continue working in the job I love. My eyesight has improved over the four years I’ve been using the mask and there’s no need to have injections or lasers in the eyes now.
Paul Baggs
As a 20+ year type I diabetic, PolyPhotonix has removed my deepest fear of developing retinopathy complications. I’ve been using Noctura 400 for preventative purposes and haven’t slept so relaxed nights ever since!
Alessandro Giuliano
“Over the moon didn’t come close! No treatment needed, they said! I’m so incredibly grateful.”
Linda Baker
“I was told that my retinopathy had been reduced nearly 50%”
Patrick McCrosson
“I don’t have to buy any new spectacles for my short sightedness – I can now see just as well without them!”
John Brown
Middlesbrough, North Yorkshire
“To have this preventative treatment, which could stop further eye damage, is a huge relief.”
Barbara Parfitt
Colchester, Essex
“It has already taken my legs and I don’t want it to take my eyes as well.”
David Stoddart
“I just wish I’d known about the mask earlier before the damage to my eyes happened.”
Neil Walker
Sidcup, Kent
“I’ve noticed I can now read labels and price tags when I’m out shopping.”
Isobel Foster
Crook, County Durham

FAQs

Is Noctura 400 a long-term treatment?
+

Noctura 400 has been designed to be a continuous treatment to be used every night. Taking a break from using the mask could lead to further hypoxia which is one of the main causes of retinopathy in people with diabetes. As long as diabetes is present, retinopathy has the chance to develop.

Is there a chance Noctura 400 could make my eyesight worse?
+

Noctura 400 has undergone extensive safety trials and there is no indication it will make your sight worse. Patients must attend their prescribed check-ups with their eye specialist and if sight is in decline there may be another underlying problem that requires attention.

Will Noctura 400 improve my eyesight?
+

Some patients do see an improvement in their eyesight, but not everyone should expect to notice any significant improvement in visual acuity. It depends on the patient’s condition and stage of their eye disease.

Does the light make it difficult to sleep?
+

The wavelength (colour) and the low intensity (brightness) of the light has been specifically selected to minimise sleep disturbance. Most people find that they quickly become accustomed to the light and can ignore it.

Is it comfortable to wear?
+

Noctura 400 has undergone extensive design usability trials and includes a comfortable fabric mask which has been ergonomically designed with comfort in mind. Some people may find it unusual for the first couple of weeks, but most people soon become accustomed to it and wearing it becomes a normal part of their night-time routine.
