Problem with vision?

[IHazWelshD]

I have cross posted this to the vetenary thread and hope it ok to post here also. Ok here goes..........
My horse has suddenly started to spook when I approach him from the nearside. He doesn't like any noises that side either and spins to the side in fear as though to identify what is making the noise - for example, if I walk in to his stable he is fine, but if I go to the side and my foot 'crunches' the straw he gets very tense and jumps to the side. Out of the stable he doesn't seem to like me walking towards his flanks although if I lay my hand on him and walk back he is fine. This has been happening since last Friday. He was vaccinated last Thursday and I put his odd behaviour down to him feeling out of sorts from his jab. He is eating, drinking, peeing and passing stools normally. He is also slightly headshy, but again, only on his nearside. He had a slight nasal discharge on saturday morning but that cleared very quickly and again, I put that down to the vaccination (flu/tetanus).
By the look of his bed on Friday morning he had obviousely had a good lie down. Could this be related to an eye injury? He is absolutely fine with anything being done around his offside.

He may just have had a fright to that side of his vision and or hearing when you've not been around at some point, either in field or stable - eg, mine had his stable door blow against him one day when tied up outside and was really wary of any movement (including me!) on that side of him for a few days afterwards and also if something has ever fallen into his stable from a particular side he takes a while to trust that side again! That may just be my silly pony though. I don't know with yours but maybe something blown across the field and came at him from one side or something on the yard has banged/fallen and that he just hasn't settled down from yet. Though when it's almost a week it does seem quite a long time.
