Yes sir.....I was diagnosed with 4th cranial nerve palsy back in 2015-ish. It is a very weird sensation, but it is very manageable (or at least mine has been). MRI showed a growth on the nerve, but so small, not worth the risk of gamma knife. a lot of research showed that this is common and not indicative of a cancerous growth (or can be caused by a hard hit to the head.
They originally prescribed a Fresnel Prism lens that I had put on my reading glasses on the right eye. That helped with the vision issue, but would always cause a strange and unique sensation that was visual and physical in my head when I would take the fresnel prism on and off.
With time, it has gotten better. The following are what I have done, and the symptoms that show from time to time:
-diet and exercise (I now over eat on healthy food).
-limit TV an hour before bed
-limit screen time
-wear terribly expensive sunglasses with polorized lenses. days with a lot of glare seem to really stress that eye
-unfortunately, night time games / LED stadium lights, really stress that eye bad.....Like, I really think the light show at Dudy noble is cool, but it causes a lot of neurologic visual sensations when they do it......so I just close my eyes.
-when you are tired, take a break. I do a lot of eye exercises, especially when on phone calls. focus on a object 3-4' away for 20 seconds, and then focus on something that is 12-15' away. You will effectively be strengthening the muscle to overcome the nerve affliction/deficiency.
-You will learn, when your vision splits, that there are angles you can position your head and everything comes back together. My vision will split when I am tired still sometimes now, so I position my body, and look to my right, and it all comes together.
-bright lights, and all these people upgraded to LED white interior lights that BLAST the 17 out of the brightness.....is a struggle for me....it seems to just really stress the eyes ability to focus (I guess glare), and I cringe when I go in a home and they don't dim the lights to a reasonable brightness.....in short, high Kelvin LED's (really white) SUCK!!!
* That's my brief.....it really stinks, as I like to read, and when I am tired I want to read, but my eyes just can't pull the words fully together.......for me, it has been very manageable, and rarely now, would I say it prevents me from doing anything, but in the same breath, I know my limits, and I manage all of it to try not to push those limits......point being, unless I told you, you would never know that I was diagnosed with that and have slight vision issues
*also, on the fresnel lens, I used it for a brief period of time to get over it......learning to do eye exercises was the game changer for me
