answer:There are contacts that correct for astigmatism but they can be irritating—they’re weighted, so that they stay aligned on a vertical axis, and in theory, they shift slightly with each blink. I never noticed this, but I recall my optometrist saying that it would annoy him. It sounds likeyour optometrist is talking about ordinary contacts which overcorrect, rather than special contacts designed to correct astigmatism… but if she is talking about the good ones, it will most likely be fine, especially if you’re only wearing them while running. It wasn’t a big deal for me.
