验光前课程旨在为学生准备进入验光专业学校做好准备。通常，验光学校要求至少90个学期的验光前课程，并且强烈鼓励学生获得学士学位。有些课程强烈推荐那些已经完成学士学位的学生。学生可以自由选择任何感兴趣的专业。视光学学校的录取取决于诸如学术准备，视光学入学考试（OAT）的分数以及视光学领域的一般特征和适应性等素质。学生必须直接向各个验光学校申请。学生必须通过OptomCAS（验光集中应用服务）进行申请。
The Doctor of Optometry (O.D.), or optometrist, is an independent health care provider who examines, diagnoses, treats, and manages diseases and disorders of the visual system, the eye, and associated structures. Optometrists may prescribe glasses and contact lenses, participate in the rehabilitation of the visually impaired, and diagnose and treat ocular diseases. An O.D. can also identify and manage a variety of non-ocular systemic and psychological conditions, working effectively as a member of the comprehensive health care team.<br><br>The pre-optometry curriculum is designed to prepare students for admission to the professional schools of optometry. Generally, schools of optometry require at least 90 semester hours of pre-optometry coursework and students are highly encouraged to obtain a Bachelor's degree. Some programs give strong preference to students who have completed a Bachelor's degree. The student is free to pursue a major in any area of interest. Admission to a school of optometry is based upon such qualities as academic preparation, scores on the Optometry Admissions Test (OAT), and general character and fitness for the field of optometry. Students must apply directly to the individual schools of optometry. Students must apply through OptomCAS (Optometry Centralized Application Service).<br><br>The Pre-Optometry coursework expectations vary somewhat by individual schools of optometry, and students should contact the schools of interest. In general, schools of optometry will require coursework (usually one year each) in biology, chemistry, and physics, these should be courses that are required for the major rather than survey courses intended for non-majors. In addition, most schools of optometry will require additional coursework in psychology/social sciences, organic chemistry, biochemistry, microbiology, anatomy, physiology, calculus and statistics. Some schools require observation hours and/or have a time limit for acceptance of prerequisite courses. A pre-optometry student at USD should use the suggested curriculum for the pre-medicine program as a guide in completing optometry prerequisites
