I presume you mean the hairs are not attached to him (ie. growing into his eye) - if this is the case, their eyes will get them out themselves. If you notice that he is irritated by them and they don't seem to be shifting then a saline wash should do the trick. If he is still irritated by them (this would be after several hours) then he could have a scratched eye or mild infection, thus the reason they were not clearing (and he would need ot be taken to the vet). This is not too likely and they should make their way out fo his eye by the end of the day without problems.
Of course, if you mean they are growing into his eye, a trip to the vet is def in order.
Hope it all clears up soon
