I'm blind but not to the point where I can't see anything at all without my glasses. I'm actually doing Track and Field this year and I am planning to do high jump, hurdles, 200 m, and 400 m. My friends tell me I should buy sport goggles even though they are expensive. They said that my regular glasses might fall off and break and also I won't be able to see how high the bar or hurdles are. Though, what I'm worried about are those reasons and that if I will use it often in my life. I'm scared it's a waste of money and I should just stick to my old glasses but I really want to do high jump and hurdles. Should I buy them?
