Eye test tomorrow. Better mention the "pale optic discs" which my neurologist flagged up last year. 
Suggest you request testing colour vision and visual fields...
All done today.
Maybe very slightly less colour vision in left eye, than right (particularly the pale red & pale green colour vision test). But not serious enough to be an issue .No issues on the visual fields tests (the one where you look into a plastic dome with one eye covered up, and press a button when a dot flashes in the dome).
Optic discs look pretty much the same as they did during my last test in 2018 (near enough identical when they showed the images side by side). So while there might be something neurological going on, and affecting my eyes, it's not a clear cut case. And while the optic discs might be pale, the only other comparison image was that taken in 2018, again so nothing that the optician can say for definite if it is optical neuritis etc. I did mention slight discomfort on moving my eyes full left / full right up and down, again the optician isn't too concerned about that yet.
And I passed the glaucoma screening test as well. Although optician did say if it was something neurological I eventually get diagnosed with, it's more likely that the neurological condition will affect my eyesight eventually, than glaucoma (which both my dad, and grandad had)
No change to my glasses prescription. So next eye test in two years time.
So while I've no obvious clear cut diagnosis opticians wise, to go back to neurologist with, at least I know nothing is bad enough yet that it is affecting my eyes.
The opticians was an independent chain (Ferrier & Mackinnon), who I've used for a while and gives a decent eyetest, rather than Specsavers (who I find rushes you through an eyetest in order to flog new glasses).
So just the lumbar puncture to get done next week, and we'll see what that brings.
