An eye test, also known as an eye examination, is a comprehensive assessment of your vision and overall eye health. It's more than just checking your ability to read an eye chart; it involves a series of tests to evaluate various aspects of your ocular system.
What Does an Eye Test Include?
An eye test typically includes the following:
-
Visual Acuity: This assesses how well you see at various distances, often using a Snellen chart. This measures your sharpness of vision. Source: WebMD - Eye Exams and Vision Tests: An Overview
-
Refraction: This determines your refractive error (nearsightedness, farsightedness, astigmatism) to determine if you need corrective lenses.
-
Eye Muscle Function (Movement and Alignment): This checks if your eyes align properly and move correctly in all directions without needing to move your head. Source: Cleveland Clinic - Eye Exam (Eye Test): Vision Test & Other Optical Exams

Internal Eye Examination: This uses specialized instruments to examine the structures within your eye, including the retina, optic nerve, and lens. A dilated eye exam allows for a more thorough examination of the internal structures by enlarging your pupils to let in more light. Source: National Eye Institute - Get a Dilated Eye Exam

Peripheral Vision: This tests your ability to see objects outside your central vision.

Other Tests: Depending on your age, health history, and risk factors, additional tests might be performed to detect conditions like glaucoma, cataracts, macular degeneration, and other eye diseases. Source: CareCredit - 15 Types of Eye Tests That Are Part of Maintaining Healthy Vision
Difference Between Vision Screening and Eye Exam
It is important to distinguish between a vision screening and a comprehensive eye exam. A vision screening is a quick check of your visual acuity, while a comprehensive eye exam is a much more detailed assessment of your entire eye health.
