Why You Need an Eye Exam, Even if Your Vision is 20/20

  1. An eye muscle test examines the strength of the muscles around the eye and overall physical condition of your eyes. If there’s weakness or loss of control of these muscles, it might be a sign of something more serious, such as neurological damage or physical trauma.
  2. The visual acuity test and the refraction assessment are the parts of an eye exam that everyone remembers. The famous Snellen chart (the poster with smaller and smaller lines of letters that you have to read out loud), for example, tests how clear your vision is and if you need any corrective measures such as glasses. Any blurriness in your vision will be caught at this stage.
  3. A visual field test determines how wide your field of vision is. This can change with age, and regularly testing your field of vision helps your doctor track any damage that has occurred to keep you as healthy as possible.
  4. A colour vision test may include looking at pictures of differently coloured dots and tests how well you distinguish different colours. You may have poor colour vision without even being aware of it.
  5. The retinal examination is all about the health of the inside of your eye and the tissue and blood vessels behind it. This is the part of the exam that requires your eyes to be dilated so your doctor can see into your eye. A retinal examination is done to test if there’s any increased pressure on your eye or if there are any infections, amongst other things.
