There are 16 schools of optometry in the US and one in Puerto Rico. The closest school is at Pacific University, located just outside of Portland in Forest Grove, Oregon. California has two schools and the other 13 are east of the Rockies.
Biochemistry is required or recommended by most of the schools.
Sample course plan Shown below is one way to organize most of the science classes required by the majority of optometry programs. Other science classes may be required by specific schools. For example, a school might require a year of introductory biology instead of the anatomy and physiology shown below. English and psychology, although not included in the chart below, are required by all schools in addition to the sciences. Which classes in those departments you take and when you take them will depend on your interests and background.
