Hello Customer, and welcome back to Just Answer!
Just as you were trained on the job to be an MA, optometrist's assistants typically also receive on the job training; however there are
certifications in this field, and optometrists and ophthalmologists look more favorably upon those who have the formal training, to work in their offices.
Many vocational schools and community colleges offer programs in optometric assisting, and they typically take between six months and two years to complete, depending on which program you choose.
You can see an overview of some of the courses offered, below and also schools that have programs in this field.:http://education-portal.com/optometrist_assistant_courses.html
Because you already have experience as an MA, this should be helpful if you decide to pursue the field of optometric assisting.
I wish you much good luck in your future educational endeavors!
