This has only happened a couple of times - first time about 6 months ago and then again tonight. Both times, I'd worked very hard - the first running 10k fartlek but really pushing it and tonight after a spin class. About 15 mins after exercise, I notice part of my vision is blurred - a bit just off centre , with a couple of squiggly line type things. Very disorienting, but it goes after about an hour. Any ideas? Any others have experienced this?

yep I get blurry vision if I'm pushing myself exercising - reckon it's bp related as I have low bp - vision returns to normal when I cool down though.
If yours persists it might be worth a check-up by your GP?
I would suggest its to do with heat, dehydration and possibly blood sugar levels.

Sometimes I get fuzzy vision after exercise and sometimes light headed, this does go after a short period, but for me I think it is low blood pressure.
When I last had it checked, my rested heart rate was around 42, which I was told was quite low.
As suggested by others, get yourself checked over, in case it's something completely different.
Thanks for this. I am experiencing this for the first time right now, after a hard game of netball - having not played for 20 years. It's reassuring to know that I am not going blind!
I get a similar thing on very rare occasions, sometimes after exercise but sometimes just at work, the vision comes back to normal after 30 to 60 minutes. I don't get full blown migraines but talking to people that do this is often the first sign that they are about to get one. As others have said if it worries you see a GP as the worry is possibly a trigger for it as well.
glad it's not just me. half way up the 4th hard hill on evening club run (had been out in the morning too) It was like looking through a kaliedescope. Was definately running on empty.
As soon as I started cooling down it was back to normal, and the first thing I reached for in the fridge was a jar of jam with a big spoon, somethign I never do, so body was tellign me to get some sugar in.
If that's not the early stages of a migraine I'll eat my hat.
I've suffered from migraines on and off since my early teens and I have learned that hard exercise can trigger them: both full-blown and (more often) just the aura stage that you describe. I have found that I can miminise their occurrence by taking care to be well hydrated and to make sure that I have had a snack before running. I had a rash of them last year when I started doing a hard interval session at lunchtimes but having a mid-morning snack made a big difference.

I sometimes get exercise-induced migraine, usually when I've pushed very hard and not been properly hydrated. Mine starts with visual disturbances and develops into a dehabilitating headache within about 30 minutes, if I can get some painkillers and an electrolyte drink when I first notice my vision going funny then the migraine is usually less severe.
BUT please go and see your GP to get a proper diagnosis.
Hi All,
I am feeling the same after intense weight training. I am suffering from high BP and I think that may be the reason.
I don’t think dehydration and glycogen has anything to do with it as I do drink water and take glucose after workout. The funny thing is that it has started happening only recently and I am doing weight training from a year now.
Also, I had my BP checked last week and it was 130(higher )/100(lower), still not perfect but better than before.
I don’t want to quit training so I will see my Doc soon!!!
My husband had some stress over family health and one day his vision in one eye became blurred when looking straight ahead, it was ok when he turned his head to side. Anyway it turned out a blood vessel had burst and it affected the muscle in the eye.
Jjust a thought if you're exercising and it putting stress on these muscles around the eye, this could happen ??it took 6 months for this problem to right itself !
The squiggly line thing is what makes up sleepy dust in your eyes eventually and not to be worried about, or so I have believed for ever.
I'm not so sure. I generally stay pretty hydrated and had water with me. The fact it's in both eyes seems to suggest it's coming from the brain? I also got the headache the guy's are describing above within another half hour. I had even dropped some electrolytes and nurofen after reading the post. Curious. I guess I'm trying to rule out mini-strokes etc. Might go and see the doc anyway and see what they say.
As others have said, it sounds like the aura phase of a migraine - google 'scintillating scotoma'. I used to get this regularly (2-3 times a month), sometimes when my blood sugar was low but other times there wasn't an obvious explanation. I had an MRI scan (all clear) then went on medication (beta blockers) to try and stop it happening but didn't like the side effects so decided to just live with them instead. I have no idea if this is related, and the doctor doesn't seem to know either, but about 18 months ago I discovered I was anaemic and started taking iron tablets. Since then, I get the visual thing about once every 3 months if that.
Just had this after a very hard PT session in the Gym.
Was a tad concerned but spoke to my trainer and its due to the body being worked so hard the brain has not had all the oxygen it needs to balance the body out correctly. So it basically dials down some areas of the body, one being vision which becomes impaired until you have got your oxygen flow back to normal around the body.
I get the squiggly eye warning as only had the headache once and do not want it ever again !! Def dehydration causal factor - don't forget that your fluid requirements vary considerably - normal is approx 35-40ml/kg so exercising on top of 'normal' sig increases these requirements
I had my first episode of slight loss (lasting 40 minutes) and flashing in May after a hard run, then followed by headache. GP reckoned it was exercised induced Migraine.
Had a subsequent MRI/brain scan and all OK - specialist was not sure what the cause was but usual suspects were possible: Stress dehydration, etc. It now only happens during weight training or hard exercise. It could be dehydration which is causing this as each time but not sure.
I'll keep investigating and update on here when I know more.
I am a doctor but this post DOES NOT CONSTITUTE MEDICAL ADVICE. I do however want to say that it's not really a classified medical condition or something that I came across at medical school. I just did a quick literature search to see if there's any research out there.

Exercise-induced transient visual events in young healthy adults.
This paper (admittedly from nearly 30 years ago) from the, now defunct, journal of neuro-opthalmology goes colourfully through a series of 6 case reports of healthy people (none had a history of epilepsy and only one had a family history of epilepsy) experiencing a variety of visual symptoms after intense exercise.
The paper points to several other such papers which suggest that these symptoms are quite prevalent (as this thread would suggest) and makes the similarities to visual (or ancephalic) epilepsy, however it draws the conclusion that these such events are benign (not related to a serious underlying neurological or opthalmic disease). That being said, this conclusion was drawn after the subjects in question were reviewed and investigated by neurologists often with CT scans.
TLDR: This can happen in healthy albeit dehydrated people, but equally could represent underlying disease such as blood pressure abnormalities (high or low) or underlying neurological problems. It would seem sensible to get yourself checked out to see which category you are in!
