Re: "AfterImage" in right eye only when looking up?
For me.. this has been going on for about 6 months or so I think. Sometimes I get a blue flash of light in the eye too. Lasts just a few seconds.
Had my eyes tested and the optician didnt seen worried at all. Sometimes a Visual Migraine without the headache can cause this too.. and also anxiety problems. I got worried at first because I thought it was something to do with not getting enough oxygen to the brain that caused me to see the things in my eyes, but doesnt seem to be the case really. Panic attacks can cause it too.
Its a normal part of shortsightedness to see the speckles when you look at something light.. like the sky or perhaps sometimes the screen of the computer etc. These are called floaters. Totally normal.
With the afterimage thing though.. that can be a bit more scary as its really hard to describe to someone what it is youre experiencing. Tight neck muscles could be a possible cause, perhaps trapping nerves etc too. Optic Neuritis is another possible cause.. so many different things. With the optic neuritis you can also seem to have a "cloudy" vision too at times when coming into a lighter area from a darker area. This is your pupils adjusting to the new light level. Its also probably the cause of the afterimages too with us.
I would probably advise you see an optician/doctor about it though.. just to make sure youre OK otherwise with your health. Worst thing I did was think I was OK not seeing a doctor about the problems Ive been having for 9 months or so now (vertigo, nausea, lightheadedness) and now they dont know what is wrong. That is why I suggested about the inner ear problems.. because they can spread from your sinus after an infection and cause optic neuritis and other problems.
How long have you had this for?
