Review: Oxy-Iso glasses

There a several ‘cures’ to colorblindness in the form of special glasses available. I’ve always been interested in giving them a try. Luckily got me a pair of their Oxy-Iso glasses to review.

The sporty looking Oxy-Iso glasses are made for medical purposes but incidentally also seem to help the colorblind. On their website they claim to “isolate and enhance perception of blood oxygenation under the skin, and eliminate perception of blood concentration. Also known for reducing the effects of red-green colorblindness” (


Putting the glasses on for the first time is very strange. Looking around in my apartment everything got a purple glow over it. Especially my white walls where screaming purple at me, almost fluorescent.

Once my eyes got a bit more used to the glasses I did start noticing the floor looking somewhat brighter brownish, it too seemed to emit a strange glow, but not in the same way my walls were still glowing purple – although less than they did before.

I walked up to my bookcase and looked at the different colored spines of the books in there. The reds are very bright, they seem to shift from red to a more orange tint. Greens get a bit darker, but they remain distinctly green.


I didn’t feel like I saw more color, the glasses seem to make the difference between certain colors bigger. I didn’t feel as if life as I knew it had changed.
So much for curing my broken eyes I guess.

But then I got my Ishihara test plates from my bookcase and opened it at a random page. I immediately saw a very bright 16.
It took no effort or second thought to determine the number, the dots where just completely different from the ones surrounding it.


I knew there where some practice plates in the book, used to explain how the plates work. I flipped to the next page, but immediately saw a 7, and a 5 too.

I took off the glasses and the numbers disappeared. The 16 at the previous page was gone too, all that was left was a circle made up of almost identically colored dots. I put the glasses on again and the 16 was back in all it’s brightness.
I started turning the pages and was able to see every single number, without any effort at all.

It was pretty mind-blowing to say the least.

Let me give you an idea of how amazing this is for a colorblind person.
Your parents usually find out that you’re colorblind from a school doctor who made you do a test. There’s various tests available, one of them being the Ishihara test: circles made up from dots with numbers in them.

Being colorblind, you will fail these tests – all of them – you won’t be able to see any of the numbers or figures.
At the same time, the people around you (with their perfect color vision) see all of them. They just see the number, they don’t have to think about it, squint their eyes, tilt the paper in the hopes of getting more light on it or ask someone. They just see it.

Not being able to see something everyone else just sees is frustrating. There’s nothing you can do about it, you just can’t see it. To make things worse, almost all people without colorblindness will look at you in disbelieve when you’re not able to see the bright 16 in front of you.

They’ll ask you “you really can’t see it?” with a wondered look, as if you’re not trying hard enough.

This can be tough on you growing up, as you can read in the guest article by Karen published earlier.

So being able to just see this mythical 16 appear right in front of you – effortless – is really, really amazing. I can only describe it as magical.

But magical enough to be worth the $297 the glasses will cost you? Difficult to say.

Your eyes do get used a bit to the purple after a bit, but I couldn’t stand having them on for long periods of time.
Everything looks different, not just the colors you normally have trouble with. It might just be me, but having everything look a bit fluorescent is just a bit too much and gave me a headache after a while.

They’re not the cure to colorblindness either, that would require my retina to actually pick up the wavelengths I can’t see. The glasses merely increase the difference between certain colors, amazing none the less, but not life changing in terms of color sight.

The glasses feel as if they’re most suited for practical uses. They’re really good for the things you normally can’t do alone, I can see myself using them for lots of things in the future: working on electrical wiring, reading a chart, defusing a bomb or playing trivial pursuit.
Being able to do these things alone and without any effort or help is absolutely amazing.

If the glasses are too pricy for you, you can also get separate uncut lenses, small enough to take with you and use whenever you need it. I can see this being really useful in all kinds of situations.

Have you tried these or other glasses? Let me know in the comments, I’m really interested!

    I have selected for Indian air force but I have failed in medical for color blindness…so they keeping the remedical to me…Hw should I cure it ?????plsssssss tell me……

  2. Andre

    I have tried everything and let me tell those who say these are fake are half right, half wrong. It’s not the glasses that help it’s the tinted lenses. Nowadays to past all the test I have three tinted plastic sheets (red,green and blue). These help me to see the colours. For example if the plate is supposed to give people who can’t see red some trouble you put the red sheet over it and the number magically appears. The glasses are just the company getting some glass, colouring it and charging $300.

  3. kevin

    Where can get that glasses

  4. roger mchone

    How do I get those special glasses?

  5. Tutor Fortune

    The Oxy Iso correction glasses is fake. As I write you I have one on and still can’t see the figures in the Ishihara plate except for 16 which I can still see without the Oxy Iso lenses.


    I HAVE SUFFERING FROM COLORS Blind ? and next week i am going for medical examination ? please give me some tips to see the isharia test series ????? in this email id ( please sir/madam give me

  7. Igor

    Frank is right, why 2 buy 239$ glasses when you can have free paper 3d glasses.

  8. Igor

    I reed this article and when i look at picture of ishihara plate with n 16 how is with and without glasses i take my 3d paper glasses (0$) and look at left photo through red filter i also see 16. I think that those expensive glasses is nothing than taking nice amount of money from your pocket.

  9. jake

    i think this one is not the proper cure for those who has color blindness…..

    So, you can learn about some of the latest breakthroughs in vision science – including color blindness – at University of Washington Medical Center, in Seattle. Dr. Jay Neitz and others are researching a cure for color blindness, as well as myopia. You can hear all about it on the UW Medicine Pulse Podcast, over at You don’t even have to listen to the whole thing (which is only 20 minutes long). If you scroll to the bottom of the page, there are a few excerpts that focus specifically on color blindness, so you can go directly there.
    I know it sounds like spam, but I figured anyone who’s here would be interested in knowing as much as they can about color blindness and what’s being done to fight it and fix it.

    This is nothing new. Colored lenses has been around for a long time and unfortunately the only thing they do is to add contrast to the colors you are deficient in and reducing contrast for the ones you usually see normally. I tried the Chromagen lens about 10 years ago and while it first gave me a wow-experience due to the high-contrast reds, I soon realized I could not live with the effect it had on other colors. Also, the profession I was seeking did not approve of any color lenses beeingbused when testing for color blindness. So it was really a waste of time.

  12. Frank

    Did anyone notice that the red lens of old 3D glasses also let colorblind people see what’s on Ishihara?

  13. Steve Perry

    I wear corrective lenses, so would I wear these over my regular glasses? That seems awkward. or would I have them ground to fit my prescription?
    Is there some store where I can try on a pair?
    I live in zip code 92656
    thank you

  14. Anon

    While I’ll admit in the picture, it does look very purple to my eyes, who’s to say that it doesn’t look “normal” in your eyes?

  15. Manuel

    well i don’t see the number on the simulation, thanks i don’t spend my money.

    Our Oxy-Iso eyewear is definitely not a “cure”. An ‘aid':

    Many filters can allow one to see the Ishihara plates, although by no means “all” or nearly all. Of our three technologies, for example, only one should help, and only one does help, with the Ishihara test. But it’s true that the Ishihara is fairly easy to beat, and alone wouldn’t amount to a great test. The colorblind folk who tried our Oxy-Iso in the context of demo-ing it for its intended blood-detection capabilities, and who reacted positively to it, were reacting to its ability on skin and in and around the world, not on Ishihara tests.

    Filters remove light, but it doesn’t mean they remove information. It depends on what information one wants, and on what one is trying to amplify. In the ‘blood’ domain, our technology amplifies the signal for hemoglobin concentration and oxygenation (depending on which tech we’re talking about) by blocking bands which are noise or counter-signal. For colorblindness, filters can be designed to amplify the signal for which one is deficient.

    If you have the most common form of color “blindness”, it’s not that your retina doesn’t detect certain wavelengths of light. It’s that two of your detector types (long and middle wavelength cone receptors) are less different in their spectral response characteristics than in normal vision.

  18. Kirby

    Checkout for color vision correction. They have a 100% success rate and guarantee success with passing the Ishihara color test.

  19. Joey

    There are various types of glasses available that appear to “treat” colorblindness, however, no “cure” for colorblindness exists.

    I’ve also heard of “The ColorCorrection System”, and they seem to have good reviews on their website. Does anyone have a recommendation on this method?

    They appear to have glasses AND contact lenses?

    • Tim

      I have gone to Dr. Azman for the color-correction lenses. I opt’d for the glasses since I do not need “normal” glasses. I am a designer and artist so I figured I would give it a try to see if it would help. It did.

      Since every colorblindness is not exactly the same, they go through a lengthy process of figuring exactly what hues are difficult seeing. Based upon that the tinted lenses they provide are specific for that degree of colorblindness.

      I sheepishly describe my reaction a day or so after I got them.

      Also, shameless plug to my inspired colorblind artwork based on this experience.

  20. ColorB

    Michael Bach is right- why spend $297 for glasses that let you see Ishihara numbers when a $2 red pair from the drugstore will do the same thing? All you are doing is defeating the constraints of the test by making the number darker.

    • BlindColor

      ColorB,What red pair lense which costs $2 will do the same thing? can you please name it? Thank you

  21. health

    In all honesty this became a fantastic indepth report however as with every great copy writers there are a few details that might be worked about. But in no way the actual less it absolutely was exciting.

  22. Michael Bach

    It’s really sad that these glasses are seen as a cure for colour deficiencies…
    Of course, nearly ALL coloured filters let you see the test figures in Ishihara plates, but you’ve not “cured” colour blindness, it’s is just shifted to other colour combinations – and amplified, to boot, because all colour filters REMOVE information.

    • Colin Hooper

      I agree, the filter helps you see specific tests but it still does not help me identify them outside of a test environment. It did not help me with the books at all.
      I was also able to ‘pass’ an Ishihara plate test on my laptop screen by tilting the screen backwards and viewing it from a different angle. Incredibly it said I was not colour blind when I finished!
      About 8 years ago I took a colour blindness test for air force entry. This was in a university testing facility…I failed with flying colours haha

    Can I just say what a relief to search out somebody who actually knows what theyre talking about on the internet. You definitely know learn how to convey a problem to mild and make it important. More people need to learn this and understand this side of the story. I cant imagine youre not more in style since you definitely have the gift.

    My cousin once bought blue-blocker sunglasses. They worked a little bit, but I think the other colors suffered and all looked alike.
