No schools in Nevada or Arizona. I dont think being a part of a pre-opt club really helps or hurts your application. Pretty much every person can claim to be part of such a club. Something like working for an optometrist or doing a lot of shadowing of doctors shows your interest a lot more than being part of a pre-opt club. I was definitely not in one in undergrad, i dont even think my college offered one, and it didnt have any negative effect on my application
