    I'm loosing the vision in my left eye, no remedy (with correction, right one is fine).

    Not a problem here, with one road and one lane each direction, and a 25 mph maximum speed limit, but I'd like to make one more road trip to the USA.

    Are there any one-eyed riders here, and how do you cope on multi-lane roads?

    Advise?

    I've got a friend that has a glass eye , he's been riding for years. His left is his good eye , he prefers the right side of the lane he's in.

    Based on human visual factor studies, in reality binocular vision which give you depth perception is only good for an approximate distances of 60 feet or so. Beyond that distance everything is basically monocular vision. Distance is then judged by relative size changes. This is based on the Head Up Displays (HUD) in military fighter. They must be in focus while the pilot is looking out on horizon (focused at infinity). HUDs are adjusted with a focus at 60 feet or greater.
    All this mean is you should be fine riding. Many people with two good eyes don't see what is in front of them.
    Since you loss is gradual you will adapt.
    Go Ride!

    Not worried about depth perception, but the loss of periferal vision on that side on a multi-lane road if not in the left-most lane, unable to look over the left shoulder and check the mirror blind spot, etc.

    Good point I had not though of that. Perhaps multiple mirror on that side could help compensate. I flat mirror in the usual place and a convex wide angle bar end mirror for the peripheral view.

    I just feel no one should concede to limitation. My brother does a volunteer lot of work in adaptive sports programs: snow skiing , sailing, windsurfing, etc. Those programs work with people to push their limits.

    There are more such riders, and even more such drivers, "out there" on the road, than you might think.
    Macular degeneration or other conditions affecting central or peripheral vision in one eye.
    And (though not so much in the younger generations) some who have failed to develop good vision in one eye.

    I haven't heard of any statistical evidence that they are involved in more than average crash incidence.
    And anyway, good road technique requires frequent scanning/shifting of the gaze back and forth along each side of the road.

    As CaptCapsize says, moving along the highway is essentially a monocular experience.

    btw, you haven't said whether your bad eye's peripheral vision is on a losing path.
    Best wishes anyway.
    I expect you'll find, in 12 months' time, that you feel quite unfazed about the riding.

    Then why haven't they piped in? :)

    Macular degeneration and glaucoma (peripheral), although the glaucoma was caught with only trivial damage, and is being treated with meds.

    Meh, One of my buddies rides with one eye. He's pretty hard core & it hasn't stopped him.

    In a bike club that I rode with back in the '70s, we had two guys
    who had only one eye, and one guy who had only one leg.
    They were some of our most avid riders.
    The human mind is amazingly adaptable.

    Thanks, Pagomichaelh.
    Yeah well, "one eye" would be a lot more common in car drivers than bikers (in absolute numbers, of course).

    Plus, how many people are frequently reading Perfect Line? . . . Home Page often shows 1,000 to 2,000 viewers ~ but some may be in the permanently logged-on category rather than paying frequent attention. And may well be looking elsewhere than Perfect Line forum.
    Or may not wish to comment.
    And many who are (in visual acuity) effectively "one eye", do probably consider themselves "one and a half" eyes.

    Sorry to hear about the macular degeneration ~ there's not much joy to be had from the doctors, there.
    I hope the glaucoma has left at least some degree of peripheral vision, to give you a bit of useful "movement detection" ability to that side (plus some sense of scenery flowing past you as you ride/drive).

    So I hope you can remain a "one and a halfer" !
    Best of luck.

    Well that sucks but you can still ride. I hava a friend who manages to maintain his pilots license and he is blind in one eye.

    I only have one good eye. My left is lazy/significantly worse vision. I do have some use of it when riding for peripheral vision, but honestly, I always do a head check before merging or changing lanes, left or right, so one eye is plenty. As someone else said, at any distance relevant on a long motorcycle ride, relative position is gauged far more by apparent size and the increase or decrease of it.

    These forums are chock full of One eyed riders. Just look in the KTM, BMW, HD threads for a start.
    Sorry, couldn't help myself on that...just been browsing through threads in different forum sections.

    My dad was blind in one eye and never had an issue with driving, although he only rode a moto once.
    Depth perception was an issue for him and he hit many parking curbs and I can remember pulling a but far forward and hitting a few stationary objects when parking. Nothing bad though because he knew...
    If you find you can't turn your head enough, let go with your arm in the direction looking and twist your whole body. Well at least the left side... right might be a bit dangerous to do that.

    Oh and don't expect a discount on glasses/contacts. They charge the same, even if you just need one lens.

    Well this hits home. I was doing fine with some heart problems, everybody dies, but was diagnosed with macular degeneration in my right eye when I went in to see about getting cataract surgery so I wouldn't be "burdened" with glasses anymore. How freaking depressing. It's not the big health problems it's the problems that keep you from doing the things you want to do. I decided to retire a couple of years before I had originally planned too in no small part because I'm really not that comfortable splitting lanes 80 miles a day any more. I've become the slow guy who moves over for everybody from Vespa's to open pipe Harley's. I can see open road traveling and fun in the mountains being doable with sight in only one eye but the close urban and freeway riding I do for transportation is already becoming a bit of a challenge.

    I didn't know about the problems until after cataract surgery. Per the doc 'If you can't see out, I can't see in'.

    I am very strong right eyed, in fact I cannot read or do any detail/close focus with my left eye, though I do have depth of field, peripheral and color in the left eye. I was cross eyed as a kid, corrected back when I was seven. But the surgery on my left eye didn't accurately align my lens with the back of the eye and that part never really developed. So I am 20/20 on the right and like, 20/400 on the left. Put it this way, when I do the eye chart segment of the MSF BRC classroom, I show my students I cannot read the eye chart with my right eye covered even at less than an arms length from the chart, to emphasize being aware of your limitations and to adjust your riding to it. I've been riding 45 years and nearing 300,000 miles, and I sense no limitation in traffic riding because I am aware of it and compensate for it.
