A comprehensive eye exam, offered only by an ophthalmologist or optometrist, looks at both eye health as well as your vision. Your doctor will check for:

While tests will vary based on your doctor and your medical history, most comprehensive eye exams include the following:

  • Visual Acuity to assess the sharpness of your vision, usually using the “Big E” or Snellen chart.

  • Visual fields test, to determine if you have blind spots or peripheral vision issues.

  • Cover Test, which can identify strabismus or binocular vision problems.

  • Retinoscopy, autorefractor or aberrometer, to approximate your eyeglass prescription.

  • Refraction, to fine tune the final eyeglass prescription using a phoropter.

  • Slit Lamp exam to detect common eye diseases and conditions. The instrument allows your doctor to examine the structure of your eye to assess its health.

  • Glaucoma test, known as tonometry, measures the pressure within your eye.

  • Dilation of the pupil and ophthalmoscopy to examine the optic nerve, retina and blood vessels.
