Earplugs are a great idea. I use them all the time if I am anticipating a noisy situation, even long road trips in the car. Too much sound makes me uncomfortable! I would need them anyway for reasons concerning the protection of my hearing. Lots of people ignore this consideration and suffer hearing damage because they're too macho to think about protecting themselves.
Sunglasses are useful in extremely bright settings. Your eyes can get sunburned, too, and too much sun exposure for too long can contribute to the risk of forming cataracts.
