About NAION Life — A Patient-Founded Resource for Sudden Vision Loss
Built from personal experience by a NAION patient, for patients and families navigating life after diagnosis
About the Author
My name is Michael Brown. I am a NAION patient.
I woke up one day to find I had lost the vision in one eye — suddenly, painlessly, and permanently. The diagnosis was Non-Arteritic Anterior Ischemic Optic Neuropathy. I was told there was no treatment, no reversal, and no certain prognosis for what vision might remain.
What followed was a search for information, community, and honest answers about what life with monocular vision actually looks like — not from a clinical standpoint, but from the standpoint of someone trying to navigate daily life, manage fear, and find a path forward.
I found medical literature. I found clinical descriptions. What I didn’t find was a resource written from the patient’s perspective — practical, honest, and focused on the reality of adapting to sudden vision loss.
So I built one.
NAION Life is not a medical site. I am not a physician.
Nothing here should substitute for the advice of your medical professionals. If you notice anything different about your vision — sudden blurring, a dark spot, loss of peripheral vision, or any eye pain — seek medical evaluation immediately.
Most people’s first instinct is to call their optometrist. While that’s understandable, NAION requires evaluation by an ophthalmologist, and ideally a neuro-ophthalmologist — a specialist in conditions where the eye and nervous system intersect. Many general practitioners have never encountered NAION and may not recognize it. That is not a criticism; it is simply a rare condition.
If you cannot reach a specialist immediately — and in rural areas, appointments may be days or weeks away — go to an emergency room. The ER cannot diagnose NAION, but they can rule out a stroke or other life-threatening conditions that present with sudden vision loss. That matters enormously in those first hours. I was fortunate: the ER team arranged an ophthalmologist appointment for me the following morning. Not everyone gets that.
Here is the hardest truth, and one worth knowing early: by the time most people realize something is wrong with their vision, the damage from a NAION event has essentially already occurred. The optic nerve injury happens fast and silently. This is not said to cause despair — it is said so that you stop blaming yourself for not acting sooner, and so that you can focus your energy on what comes next: adaptation, neuroplasticity, and rebuilding.
If you have just been diagnosed, or if you are supporting someone who has: you are not alone, and the fear you feel right now is not the permanent condition. It gets better.
The intent of this website is to provide a hopeful and promising attitude for living with sudden vision loss in one eye.
The first year is fraught with shock, fear, anxiety, and challenges of all sorts. The hope lies in the fact that there are countless people who have adapted to this new way of life. I have the benefit of an example of a family member who has been living quite well after his event ten years ago. He said it took about 9-12 months to adapt. He does everything he did before his visaion loss and all but forgets he is monocular.
Though NAION mainly only affects vision in one eye, a separate incident, though remote, is possible in the other eye, information about all levels of vision loss will be included regardless of cause.
Also, you may notice an absence of graphics, color and fancy fonts. This is on purpose in an attempt to cater to those that have various sight challenges, including color blindness, and who may be relying on various technologies to read and hear the content. I hope to dress things up as I get more familiar with Accessibility solutions for the blind and vision challenged. Accessibility is a complicated and complex issue that will take sometime to understand and implement.
This website is a work in progress. I considered waiting until I had a polished product to share but decided to start with barebones and invite whatever audience comes across it to put in their two cents, thereby making it a NAION community affair. I have leaned on AI for some information and to aid in content and structure. The information garnered has been checked for accuracy, however all information, suggestions and advice, stated or implied, should be confirmed by your Primary Care Physician or ophthalmologist.
