Yes sure sorry for the late reply.Could you take a picture of the other eye so we can compare?

PossiblyLooks like there might be something lodged in there?
I shall try thank you but he is very scared of me currently and is hard to hold.It's possible, as was suggested above that there's a little piece of shed just under the eyelid (nothing I can see, but you never know). You could gently rinse it with warm water: dip a clean finger in warm water and transfer a drop to the affected eye. Keep and "eye" on it and see if it improves.
