I think that blinkers are to keep the horse focused on you. Not that everyone
would agree but it works for me so I do it. You are working with a horse or
horses that are out of reach, no leg or body contact only reins, voice and whip
so every little bit helps IMO. But every horse is different and if it works for
you go for it. I'm old and a little set in my ways ha, ha, ha. but not too set
as I am willing to try new things.
