I know that horses will look at something going in one direction and spook etc and do the same thing with the other eye coming back, but this morning my spooky so and so ignored a man up a ladder going out on the right side but coming home seeing him with the left eye totally panicked and nearly had me off! Vet checked his eyes on last visit, but wonder if horses can be short sighted in one eye like us ? Perhaps this is an obvious question to some of you but not to me!
