This sounds very weird, but ever since I was 12 I have these moments when I would go blind. What happens usually is that I would first get really dizzy, not in my body, but just in my head (hope that makes sense). Than my vision would go blurry and than everything would turn black.I can still function. I am still awake, I just can't see anything. It is scary cause it happens at random. It even happened once or twice while I was driving. Other times I get tunnel vision, where my range of vision is so narrowed and it is really scary.
I know it is not puberty, I'm almost 21 and I shouldn't be experiencing this. It may be stress causing it, but I don't know how.
I just don't know what could be causing this and if there is any way I could prevent this from happening again.
Patience. It's only been 10 minutes since you first posted. It taks time for people to read the posts.
My first ocmment would be that you shouldn't be driving any sort of vehicle if you are having episodes of blindness. You could cause an accident that could be serious.
Have you been to your doctor about this? Has he referred you to a specialist/ If not, you should be getting into someone who can order an MRI and see why this is happening. Have you been into you eye Dr? Not an optomotrist, but a opthomologist. Someone who can help. It may be pressure behind your eyes causing the tunnel vision and blindness. Either way, make an appointment to see someone...and please stay off the roads.
The reason is because when it first began, they just thought it was the same thing as when you get up too quickly. Then it was thought to be stress. The reason why I haven't been to a specialists is because we can't afford it.
You really do need to see someone - a Neurologist and an Opthomologist. You can be having what's called ocular migraines or "silent migraines" - this means you get the aura symptoms but not the pain. I get them BUT I do not lose my vision completely - More like I lose peripheral vision in one eye or get what I call "wavy heat" vision. Also get the dizziness and feeling like I may pass out. Sometimes I break out in a sweat all over and feel disoriented etc.
The first time it happened I thought I was having a stroke and did not believe it when I was told what it was (9 years ago now). It still happens and it still scares me!
Please get checked out because it can be something much more serious. I know you said you can't afford it but you need to get checked. Maybe next time it happens you can either have someone drive you to an ER or call an ambulance? I'm pretty sure they would be obligated to check some things out.
