Pre-Optometry programs

Hi, I am an upcoming high school junior. I am currently very interested in optometry, but after reading things online, I am beginning to have doubts. At the same time, I feel that as a high school junior, these doubts shouldn't come into play quite yet. Which leads me to my question - Does the college you attend as an undergraduate affect anything with your changes of acceptance into Optometry grad school? For instance, if I enrolled in Berkeley for my four years undergraduate degree, would it possibly make it an easier transaction into Berkeley's optometry school? Or will there really be no difference, I could attend a college without an optometry school?

Hope that makes somewhat sense... this is all very confusing for me, and I would massively appreciate some help.
