hi pushpendra,Candidates satisfying the eligibility requirement for the B.Optom course have to appear for the EYECET examination. The EYECET exam is the centralised, combined, entrance test for entry into optometry courses, which is universally recognised all over the country.

B.Optom course is of 4 year duration. The first 3 years teaching is followed by one year of internship for clinical and trade experience. The optometry course covers a wide variety of subjects, including physical optics, knowledge of optical instruments, general anatomy, physiology, abnormal and pathological conditions of the eye and the methods to measure refractive errors and their correction, hope this helps , good luck

I think most institutions conduct individual Optometry entrance exams for admission into B.Optom. For instance, AIIMS conduct AIIMS Optometry test for entrance to bachelors of optometry, BVP conducts EYECET, etc.
