I am writing this to give people a better understanding of this eye problem I have contracted NMO in 2019, (Neuromyelitis optica, or Devic's disease, is a rare yet severe demyelinating autoimmune inflammatory process affecting the central nervous system.)

I knew a few people with this problem, the other day, what I heard was a young man, in his late twenties got the same illness, but his loses both eyes. (That's devastating.) Mind you a week ago everything is fine perfect, it takes 3 days to take you down. (See pict below to understand) This is my experience and everybody's system might not be the same.

Everything is tuned and adjust, went for regular check-up without fail for the past 2 years, and it was my time for the covid booster jab. (Prior to the booster jab, got a blood test and consultation before I take the jab, everything is in order.) But as for me, I need to take a double dosage due to the medication and medical conditons, and I took it. I was taken ill for 2 days, weak, lethargic, I recovered after a good 2-day rest, back to my work as a web designer, my vision is up and down, I told my wife, the progressive lens is failing (got this less than 2 month ago), only the single focal lens works, the next day I try to make a payment online. (see picture). I can hardly make up the words on my credit card. I took a picture to enlarge it, but I still get this. Oh no. This spell Danger.

I called the medical officer who attended to me past 2 years, she immediately allocated an appointment the very next day, to see the eye doctor.

When I finish the first set of tests, they suggested that I get hospitalized and do a thorough examination.
Gone for a complete body scan, the neurologist suggest "high dosage drips" and see if the condition can get better, and a few many blood test, they suggested Plax or Plasma,  (An exchange transfusion is a medical procedure that's done by removing and replacing your blood with blood or plasma from a donor.) Done that 2 years ago, and the experience isn't nice at all. (lost left eye vision completely after the 3rd plax, that was my point of view, it could also mean, it stop that from attacking the right eye, I accept it as unforeseen circumstances, no further queries. What action taken is for good.)

This time round I only have my right eyes left, nothing to fall back on, was a very difficult discussion. My vision is dimming as time goes by. I opt-in. Grace of God.

Compared to before this incident, my eyes conditions drop from 100 to 30. Duly because when I put on the glasses I get 100% visual comfort, and 70% without eyewear distant object is still comfortably alright, just text or finer things are not in focus. But after attack, the glasses must be put on to achieve 30-50 percent of minimal visual comfort despite blurness and darkness, under different light ambiance.

This is based on my own encounter, everybody's condition is different, I hope this is useful to you. Otherwise, stay safe.

According to my doctor, it has nothing to do with my long hours in from of my computer, and also the cigarette I have been smoking since 2019. (Somehow after the plax, I am freed from cigarettes, the urge has completely disappeared.) Not sure cured by the plax or stayed too long in the hospital.
