eyes water after riding out

Question

Answer
Hi Bob,
Is your friend the one with the watery eyes or is it the horse? There is an eye care product called "Clear Eyes" for horses and its sold in Petsmart for about $6. It basically relieves irritation due to dust, dirt and wind. Have your friend put a few drops in his horses eyes before there ride and see how he likes it. As for the horse feeling tired you would have to consult a vet abut that :)
