An optometrist is a health service provider who is involved exclusively with vision problems. Optometrists are specifically educated and trained by an accredited optometry college in a four year course, but have not attended medical school. They are state licensed to examine the eyes and to determine the presence of vision problems. Optometrists determine visual acuity and prescribe spectacles, contact lenses, and eye exercises. Optometrists may perform all services listed under the definition of an optician.
Some states permit optometrists to give limited treatments of some eye conditions.
