Regular comprehensive eye exams can help you protect your sight and make sure that you are seeing your best.

Eye Exam

What does a comprehensive dilated eye exam include?

A comprehensive eye examination includes: dilation, tonometry, visual field test and visual acuity test.

  • Dilation: Drops are placed in your eyes to dilate, or widen, the pupils. Your eye care professional uses a special magnifying lens to examine your retina to look for signs of damage and other eye problems, such as diabetic retinopathy or age-related macular degeneration. A dilated eye exam also allows your doctor to check for damage to the optic nerve that occurs when a person has glaucoma.
  • Tonometry: This test helps to detect glaucoma by measuring eye pressure. Your eye care professional may direct a quick puff of air onto the eye, or gently apply a pressure-sensitive tip near or against the eye. Numbing drops may be applied to your eye for this test. Elevated pressure is a possible sign of glaucoma.
  • Visual field test: This test measures your side (peripheral) vision. It helps your eye care professional find out if you have lost side vision, a sign of glaucoma.
  • Visual acuity test: This eye chart test measures how well you see at various distances.
