54 now. On chattery braking bumps, its hard for me to see. I feel like my eyeballs are bouncing around in there. Not sure if its always been this way or if the eyeball ligiments are loosing elasticity or some wierd old thing like that. No one I mention this to has this experience. Anyone here experience this?
 
We experience it in airplanes in the right turbulence conditions/frequency. It makes seeing the instruments right in front of us impossible, or nearly impossible. On a bike, I would think it could be controlled with the right suspension setup, but that means more than just the right equipment, possibly custom tune to help overcome factory deficiencies and compromises.

Can you tell us what bike and what suspension?
 
There are some stutter bumps I had been charging through on my rigid fork which rattled my cage like nothing ever before...I know the feeling you describe and wondered if I too was getting too old for this crap.

I was used to doing them on my full suspension and tended to enter with nearly the same speed. It worked well for blasting through but the toll on my body seemed significant. At one point I wondered if I had concussed myself without actually running into anything due to a significant and persistent headache and symptoms that reminded me of a concussion/migraine...
 
There are definitely medical conditions that can affect your eyes. If it is still there after going through your suspension, or if it gets worse, then you should see a specialist.

One of my friends has something similar to what you describe, but he sees floaters over rough surfaces. In his case there is stuff in his eye moving around.

I had a complete opposite experience to that a couple of weeks back. Took my new ebike (190mm front and rear pole) to do gondola runs down the fast jump lines to get my eye in on the jumps on the new bike.

There was some fairly chucky stutter bumps at on several parts of one track. They were also at the fastest point of the track too. You hauled through that part of the track.

I was whooting and hollering in joy because I could see the stutter bumps, I could hear the wheels bashing through them. But I sailed above them on my plush dirt couch..... no eyeball shudder at all. It was smooth AF!

Mad that steed is glorious.
 
I know what you're talking about. Usually only happens to me when I'm stiff on the bike and the vibrations are passing through my body and into my head. It helps me to really loosen up before dropping in, like literally sitting in race start gates and bouncing around, moving the bike and my body to get and keep loose.

I'd imagine what you're experiencing is some combination of suspension stiffness and body stiffness. If both are working well, your head should be still enough to see well and be stabilized away from the bike and your body. Try some stretches and mobility exercise and see if you've lost mobility in anywhere specific that might be causing you to be less dynamic on the bike.
 
Couple of possibilities based on my personal experiences on rough terrain. This may or may not be contributing to your issue.

1. Bend elbows more to isolate the upper body from the rattle. straight elbows transmit the stutter right up to your head.
2. Don't brake on bumps. I've found on washboarded runs that I have to pick my spots to brake. Braking on the washboard sections makes it ten times worse.
 
I would recommend visiting your optometrist and if necessary, a neurologist. There are lot of potential causes, and it's good to rule out the scary stuff. My daughter experienced this and while initial indications were something scary, further testing determined it was likely a virus causing buildup in the inner ear. Quick, non-invasive treatment fixed her up.

Reading this, I had to laugh. I have had the eyeball shake stuff, but it has been a long time. I think it was when I had crap or no suspension and was going balls to the wall in races. I'm 53 now and have noticed no increase in eyeball shake. A noticeable decrease over the years, likely due to functional suspension.

Happens to me, too. I find that the more out of shape I am, the worse it is.
 
Yes, but it's primarily when I am riding a fully rigid single speed. When on a well set up full suspension bike the rattle and even the floaters are much less noticeable. **** like this only gets worse as we age. Wait till you hit 60+.... There is a reason no one our age is racing against Jett Lawrence or Nino Shurter, Tady Pogacar etc etc. Even with decades of top level training and racing and state of the art medical help, athletes age out 'cause we're degrading. Slow down, and make sure you crash less. It's more about clocking hours and hours of use instead of weeks and weeks in plaster.

Yes. I have mild astigmatism in my dominant eye. Some sunglasses and safety glasses really mess with my vision. The more curved lenses create a sort of fishbowl effect. Any kind of rough stuff with those makes me feel dizzy. I also wear contacts to correct short sightedness and in certain situations it's enough to vibrate the lenses around.

Did you ever play an outfield position in baseball? Did you ever wonder how some people can catch the ball while running at full speed?

Soften your arms- let them absorb some of the shock.

I don't really belong in this subforum because I'm only 36, but I get it too when I've been off the bike for a while. I think my arms and legs get less used to absorbing the shock from the trail, and I think my back/neck mobility is decreased from not riding as well, my neck sort of "runs out of travel" and can't compensate for the vibrations as easily. I make a conscious effort to keep my shoulders back, my hips rotated forward and my arms and legs loose.

I've got astigmatism too, I've found that the pupil distance measurement is the main factor that drives the fishbowl type distortion for me. I can get used to it after a day or so, but if I switch back and forth between sunglasses and regular eyeglasses that have different pupil distances, it really messes me up. I ordered my glasses and my sunglasses at the same time from the same place (Roka brand, dope glasses, can't recommend enough) to make sure this didn't bother me and its worked out well. The, um, $600 bill was pretty unpleasant though.

As for contacts, try a different brand. I had the jiggly lenses on my Acuvue Torics, but I've got a set of Bauch and Lomb's that don't move on me and I see annoyingly well. They're not as comfortable as the Acuvues were though.
