Wow, you are so lucky to have good vision. We spend about $600/year OVER what our insurance pays for eye exams and contacts. This year I spent way more than that, because insurance only pays for glasses OR contacts, not both, but the girls' glasses were so old they weren't good for back-up any more, so I had to pay for the glasses outright.
And let's not even talk about dental! My DDs have enamel defects, so even with good hygiene, they still get cavities.
We put $4500 in our HSA and $2000 in the FSA and it's ALL gone.
