During eye testing, your optometrist will ask about your overall health, lifestyle, vision quality, and any eyewear you may use during the exam.

An eye examination comprises three key components:

- Tests to examine your eye’s outer surface and your eye movements

- Tests to check the condition of your inner eye

- Tests to determine whether you need new glasses or contacts

The following activities may be performed during your eye exam, with your optometrist explaining each one as you go along:

- Letter reading on a chart using multiple lenses. Other examinations are available if you cannot read, such as matching letters to pictures or identifying images.

- Getting a view of your eye interior using an ophthalmoscope. This will have the optometrist positioning themselves near you and directing a bright light into your eye. You’ll then be instructed to look in various directions.

- The optometrist will also perform a muscle control check to ensure that your eye movements are accurate.

- To detect glaucoma or problems with eye pressure, they apply a pressure check using the ‘puff of air’ test.
