I've been riding for five months now and one day I would really, really love to learn to jump. I was born with no 3D vision and cannot determine how far something is from me (I can tell simple things, but if someone throws a ball my way 9 times out of 10 it'll either hit me in the face or I'll miss completely) and I'm concerned it'd prevent me from jumping because I cannot definitely tell how far away a jump is/distance between jumps just by looking.
Do you rely more on counting your horse's strides than your sight to know when to lift yourself out of the saddle etc?
I know I'm far too inexperienced to even look at a jump (no pun intended :P) but I'd love to have a crack at it one day. Any input/advice will be much appreciated.
