Dizziness whilst riding

[Doovy]

Well today was an usual experience on the way to work today on my bike.

I realised I had run out of contact lenses this weekend (I have monthly sets) and had to take the train into work yesterday as I was out in the evening, so wore my glasses all day. No problem. New contact lenses are arriving at work today (Tuesday) before 1pm so I decided to ride into work with my glasses on under my helmet. I've never done this before.

I was about two thirds into my journey, riding up to the Embankment when I stopped at a set of lights and all of a sudden felt rather dizzy. I felt like my eyes were rolling around and couldn't focus on the cars ahead of me, as well as feeling light-headed. My bike below me seemed a bit of a haze too.

As I had to pull away from the lights and red lines everywhere I couldn't really stop, but I was a little wobbly. I think it was a bit windy out too which didn't help! I looked down at my speedo and saw an out of focus 20mph but I swear it could have been more.

Flipped up my visor to get some air in and took some deep breaths, after a couple of minutes I could focus again and felt a bit more in control. I felt almost drunk just a minute before that!

Got to another set of lights and sat for a couple of minutes. Felt fine after that!

Very strange, I've never ridden a motorbike in glasses before in my 8 years of riding and probably never will again. I've had these glasses for about 4 years and the strength is fine, and I have regular eye checkups. No other health problems. Probably should have pulled over to stop but quite honestly didn't feel safe doing that and felt better just rolling ahead.

Anyone else experience this with glasses at all, or just a freak moment?



TL;DR - I wore glasses for the first time on my bike and got dizzy.

I've never had that from wearing glasses. I've always worn glasses with my lid and never had an issue like that.

Are you sure the arms weren't being forced into your temples by your lid? That could have been the cause perhaps.

I have felt faint like that though, after removing my base layer that I've worn underneath my leathers. Apparently it's something to do with lowering blood pressure or something.

Remember kids, bikes aren't like lego. You can't easily take a part from one bike and then fit it to another.

Get to a doctor. That might be something simple like low blood sugar/wooziness before breakfast or it may be something more serious like the heart going temporarily out of rhythm (which happens to me sometimes).

It doesn't sound at all related to wearing glasses or not. You should get that checked out. BCF isn't a substitute for your GP.

Interesting. Yes it could have been the arms putting pressure on my head from the lid. It's a Shoei XR1100 and it's an excellent fit, so maybe glasses were a bit of a squeeze.

I wouldn't like to recreate the situation again, certainly not on a bike anyway

I was wearing base layers too but have done for the last few months so not sure if it would be down to that.

Funnily enough the new lenses have just been delivered to my desk a few minutes ago. They're in now and I can see the world again without a frame in front of my eyes!


(Really hate glasses)

I doubt it had anything to do with the glasses as it cleared afterwards. Although 4 year old glasses. Depends on how you prescription has changed. Glasses are not he same as contacts.

I would guess its more likely a build up of fumes given that it cleared after lifting the visor and riding for a bit to get some fresh air in your body.

Something similar has happened to me a few times while out in town. I found that if I don't have a good square meal before a night out, then end up staying late I get a massive energy dip around 4-5am and it feels exactly like the symptoms described, plus lightheaded and tunnel vision. The first time it happened I panicked because I thought I must have been spiked, but now I just make sure to have a lot to eat before drinking.

This sounds like blood sugar or heart. I would want to see my GP about it.
You could try wearing your lid and glasses at home for an a bit to eliminate that, although it does sound like a coincident.

P.S. I have no medical knowledge!

I wear glasses to ride and have had the same happen as what you had.

Was nothing to do at all with wearing glasses for me, the cause was the amount of layers I had on to combat sub-zero temperatures.....

Caused blood flow to be different as was tight on cuffs of jacket/around chest/neck. Loosened and removed some layers and bad-a-bing back to normal

From the description that you gave of your symptoms, I'd say that MarJay is bang on the money.
I experienced similar symptoms to you when I started wearing a new pair of specs a while ago. A simple arm adjustment cured the problem.

Try riding on the road. Far more space than the pavement and fewer pedestrians to swerve around.

[Doovy]

Hmm. I'm no more layered up than usual so really don't think it's that. Diet is usual too, so no change there. No alcohol intake recently and no drugs. Not had a blood sugar level problem either.

[Huambo81a]

Sounds normal.

I used to wear glasses. When i first got my contact lenses i went to Alton Towers. Never been so dizzy in my life, almost to the point of being sick. I'm usually fine.

Now i'm used to them, everythings good.

TLDR: Changing the way you see, makes you dizzy for a fews days.

Have seen something like this happen before. The guy was doing speeds of 150mph+ & doing some chef wheelies and stuff. Pulled bike over, got stand down and fell off it in a bus stop...I'd get yourself checked out.

If nothing else, have a word with the doc get him to give you a general check over - blood pressure/sugar levels and stuffs.

I've had a look at the evidence presented and in my medical opinion i conclude that you are 5-6 weeks pregnant.

You should speak to your GP or visit the antenatal dept. of your local hospital.

Vertigo does seem to be the issue.

Miss-sync between eyes and middle ear eh? I was wearing earphones at the time actually.. if that would make a difference?

I will make an enquiry to a qualified medical individual. Thanks for all thus far

Doctor will do blood pressure check and take blood for glucose count.
If they're fine they'll probably ask you to come back if it happens again.

My dizzy spells turned out to be panic attacks! Had to go through a 24hr pressure monitor, bloods and an ECG, they were talking about some kind of brain scan but I never followed it up, went away on its own in the end.

Point is it could be loads of things, but as above you SHOULD get pressure and blood checked, if it's not those I wouldn't worry too much.
