I'd like to think that I'd be well-trained enough that I wouldn't need blinders. A big part of ponygirl training is simple obedience, after all. Multiple years would be spent conditioning me to blindly follow orders and to never stop or turn or move unless commanded. The basic standard for ponygirls would be being able to work 12 hours a day, 7 days a week, if so required. I would need to have the stamina to do my duty and the blind obedience to ignore my own exhaustion. I will never stop or turn of my own accord - a single failure in my entire career would be unacceptable.
That said, if my owner were to wish to keep me in blinders... I can't come up with a single reason why I shouldn't be kept in them. Yes, they're probably not needed... but my eyesight would also not be needed for my job. Slaves like me wouldn't be entitled to our senses, so if my master desires that I live in a world of darkness, then it shall be so. Perhaps even my ears would be plugged to further deny my senses.
I'd be completely dependent on the tugs at my reins to know how to safely move. I'd have no choice but to show absolute obedience, and if I am being executed by being run off a cliff, I won't know until realize I'm dropping through the air. When parked, I would have no choice but to remain absolutely still, with no knowledge of my own surroundings. I'd have no idea if I'm being observed, and the knowledge that if I relax for even a second, I could be punished severely.

As slaves, our lives are not lives of luxury. They are lives that are luxuries.
It's only fair, after all. Trying to make everyone equal would result in everyone losing equally. By fully devoting my existence to servitude, others may live in luxury. Trying to myself experience luxury would be a cruel and selfish act that deprives humanity of its dignity.
