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

FAQs

How can I purchase the mask?
+

Noctura 400 is available to buy on this website. Each mask gives therapy for a period of 12 weeks. Thereafter, a new mask is required to continue with the treatment. There are often special welcome discounts for new patients and there is an option to spread the cost over 3 months interest free through PayPal. We are also offering an ongoing monthly subscription model where a new mask will be sent automatically every 12 weeks. The mask is also available in the UK from a number of independent high street optometrists as well as from the Outside Clinic, a national home-visiting optician. Please contact us for further information and we can put you in contact with a supplier near you.

Is Noctura 400 safe to use?
+

Yes, Noctura 400 is non-invasive and very safe to use. It has been available for over 10 years and has 2 million hours of recorded patient use. The wavelength of the green light is within the normal visible spectrum and not at all dangerous. The brightness of the light is at a comfortably low level and will not cause damage. The mask has been tested for both safety and efficacy in multiple clinical trials and has been awarded the CE Mark as a Class IIa medical device.

Will Noctura 400 work for me?
+

In an NHS evaluation 96% of people saw clinical benefit and across all stages of diabetic eye disease the mask demonstrated clinical repair in 66% with no associated complications. This means that Noctura 400 works for the majority of people but since everyone’s response to any treatment is unique, the speed and level of improvement can be different. Most people will see results in 3-6 months but if it’s not right for you, you can return it for a full refund under our 30 day money-back guarantee.

Does Noctura 400 replace current standard treatments such as laser or intravitreal injections?
+

Noctura 400 can be used in parallel with the standard treatments and may reduce the need for or the frequency of the other interventions. Patients are always advised to follow the advice of their eye specialist and if standard treatments such as laser or intravitreal injections are being recommended by their ophthalmologist, patients should continue to follow that advice.

Can the mask be used by children, young adults or women who are pregnant?
+

Noctura 400 has not been tested on anyone under the age of 18, and therefore should not be used by this group of patients. Noctura 400 has not been specifically certified for use during pregnancy, however the available research on green light therapy suggests that it is generally safe. If you are pregnant, or if you are planning to become pregnant, it is important to talk to your doctor before using Noctura 400. They can give you personalised advice based on your specific situation and health needs.

Is Noctura 400 available outside of the UK?
+

In addition to the UK, Noctura 400 is available in Spain, Portugal and throughout most of Europe. We have distribution arrangements in several other countries and the list is growing rapidly. Please consult the ordering page on our website noctura.com or you can always contact us for availability elsewhere and we’ll do our best to supply it to you.
