That frustrated feeling that I’d get when I was almost done with my reserved one hour indoor arena block before things started going right in my ride? Turns out it was totally valid, but not because my self doubt was correct and I needed to push myself harder - it’s because my horse was rightfully off, due to the reality that it took him 45 minutes to be able to see well during our ride, just enough time to have the only stellar part of our ride be the cool down.
Every lap around the dimly lit arena brought another slowly shifted viewpoint he hadn’t absorbed quite yet, and he’d get distracted, “sassy” or off balance at things he’d “seen before”.
👀turns out, It takes 45 minutes for a horse’s eyes to adjust to a lighting change - like walking into an indoor arena with dim lighting on a bright sunny day.
But once I knew that? It’s a super power!
Now, I don’t skimp getting lighting tokens for my ride, brighter lights inside make all the difference.
I also groom and tack up inside rather than tied in the sun next to the trailer. Every little thing I can do to accommodate that pesky 45 minute visual adaptation time has seriously changed indoor riding outcomes.
Inside to outside is just as challenging for our horses. When my moms warmblood gets lead from his stall to the barn isle and out into the direct sun he leaps over the transition like he’s back in hunter jumper training in England - that depth and lighting change has him relying on old training to complete the ask. Now she chooses a different time of day or brings him out on the shadier side of the building and he’s calm as a cucumber.
Whatever the lighting change, if it isn’t the natural pace of the sunrise or the sunset, your horse is going to have a tough time adapting to one of it’s senses being off until they can catch up.
Remind yourself of the visual difference the next time you’re asking for sudden light transitions and keep a cool head knowing you and your horse are seeing it entirely differently.
