Hi Sakshi!

To become an Optometrist, you  must complete a bachelor's degree in optometry, BSc in optometry or B.Optometry. To pursue this course you need to have science in 10+2 (PCB/M) with atleast 50% from a recognized board. This is a 3 years course and the fee varies between 10,000 to 1 Lakh depending upon the college. You can get admission by entrance test or by merit depending on the institution. Later, if you wish you can go for master's degree or any research.

Hope I answered your query, thankyou!
