I had a a bad tbi lost vision on the left of both eyes . My left ey is dominant so I close my right a lot because it would float off when I’d really focus I started crossing my eyes until the made one Vision so now I can use both eyes but I still am blind on the left and have to scan a lot before crossing paths or navigating threw a store Thad be great to be able to drive again someday I didn’t know these glasses existed till recently . Would be cool to see with better awareness
I had. Brain injury on 20th December 2018 and I was diagnosed with left homonymous hemianopia and right 6th palsy. After almost a year, my eyes got aligned back to the normal position but I still have problem seeing left. Please suggest what can I do. Thank you
So, this is going to sound stupid but how common is it for the brain to ignore the input from one eye or the other depending on what eye is "actively" being used? I ask this because when I look with my right eye my left eye is ignored and my right eye is ignored when I look with my left. In addition to this whenever I am quite tired and my eyes attempt to work "together" or rather my brain is trying to accept the input from both eyes I end up getting not just double vision but also dizziness.
Not stupid at all, the brain's visual system is incredibly complex and still not fully understood, and when it malfunctions it can cause a multitude of different effects, not all of which have been identified and named. For example, in all the descriptions of hemianopia I've seen the affected side of the visual field is shown as either totally grey or black. For me, the affected side behaves more like the 'blind spot' that everybody has because there is a small part of the retina where the optic nerve connects and no visual input is taken in. You don't normally notice it because it's in a different position in each eye and your overlapping fields of vision allow the brain to fill in the missing part from each eye with information from the other. If you close one eye you can deliberately move a small object into the blind spot and it will disappear, however you won't see a black spot in your vision, your brain fills in the area with whatever it expects to be there, so if there's patterned wallpaper behind the object your brain will fill in the pattern and y0u'll just see continuous wallpaper. My vision treats the affected side of my visual field exactly the same way. I subjectively experience a complete visual field but I can't see any changes on the affected side and if I move my arm or someone walks into the affected side I can't see it, but I still 'see' the background. I think it's like the way that if you see a cow from the side, your brain doesn't experience seeing half a cow even though that's all you can actually see (unless you're Damien Hirst). Your brain is constantly building a model of the world around you using whatever information it's getting from your senses, memory and knowledge. This can go wrong in all sorts of interesting and unique ways, a very small number of which have been named or understood.
@@chadwick-optical Disn't see your reply before I replied, good to know that it is a recognised condition, getting a name for whatever ails you is often a vital first step in getting treatment or developing coping strategies.
