An eye examination is a series of tests performed by an optometrist to assess one’s vision and ability to focus and discern objects. Other tests and examinations pertaining to the eyes and vision are also performed during an eye test to determine if there are any pre-existing or potential vision problems.

Many systemic diseases can affect the eyes, and since the blood vessels on the retina are observed during the exam, the presence of many non-eye diseases may be uncovered (e.g., high blood pressure or diabetes or neurological problems).
