Is there any university offering doctorate in optometry as a 2years course?

No, there are no universities offering a Doctor of Optometry (OD) degree as a 2-year course. The OD is a professional doctorate, requiring extensive clinical training and coursework. The standard length for an OD program is typically four years (in the United States and many other countries). Shorter programs simply don't provide the necessary depth and breadth of education and clinical experience required to practice optometry safely and competently.
