An optometrist is another professional who is an expert in providing eye care. Optometrists conduct eye examinations, prescribe corrective contact lenses and glasses and diagnose and treat eye diseases and disorders. Many states have passed legislation that permits optometrists to perform procedures such as laser treatments and injections for macular degeneration. Optometrists must have a bachelor’s degree before completing four years of optometry school and some do further training in a specialization. Optometrists are licensed by their state regulatory board and must complete continuing education requirements.
