Jockey goggles which fit over glasses?

Contacts really are the best option. Glasses under goggles slide around, itch, and are overall annoying. If you use them properly contacts are harmless and can barely be felt. My mother (and optician!) had me using contacts for riding at 11 years old, and if an 11 year old can use them properly, you can.

If you can't see far away, you should be wearing glasses when you ride. You'll find it much easier to judge distance and obstacles if you can see properly.

Plus, wouldn't you be at least 18 when you go to college?

I think that part of the problem is the current "style" for eyeglasses, which is to make them too wide. I've been trying without luck to find frames that are narrower on my face than what I currently have, because that half inch can make the difference between whether a horse knocks them off (and into the mud where I cannot see them) or not. "Sorry, we don't have any like that. these are what is currently in style."

Similarly, I find that some youngsters I am putting up on a horse or pony for a first ride have shoes that are too fat to fit into stirrups. They also don't know how to tie their shoes. Is there any hope for the future? (Sorry. Ranting too much.)

You could consider contact lenses. Hmmm. You probably already have.
