The Eye Test Explained

Your eye test is important whether or not you need glasses. In fact, working out your spectacle prescription only forms a small part of your eye test. When you come to see us you can expect most of the following checks-

  • An initial conversation regarding the reason for your visit and an overview of your visual and general health. This discussion helps us to tailor the rest of the test to your individual requirements.
  • An assessment of your current visual ability
  • Muscle checks to make sure the eyes are moving freely in all directions and are working well together
  • Opthalmoscopy: A device is used to check the various layers of the eye including the lens and retina. This part of the test reveals most of the conditions that can affect the eye. Conditions such as high blood pressure, diabetes and glaucoma can be picked up at this stage.
  • Slit lamp: If required we will use a special microscope to assess the front surface and exterior of the eye.
  • Retinoscopy: If we don’t have your previous glasses for a starting point or if we are examining children or people who can’t communicate easily, we can use this test to determine your prescription objectively i.e. without any input from the patient. In most instances the result of this test is quite accurate, however in most cases we would perform the next test to fine tune the prescription.
  • Subjective: This is the part of the test where we would show different lenses and perform a series of tests to determine the prescription in your glasses.
  • Tonometry: The pressure inside your eyes are important to measure because if the pressure is too high then it can lead to glaucoma, which is a condition that can lead to blindness.
  • Visual fields: If required we will check your peripheral vision using a machine called a field screener. By checking for blind spots in your vision we can determine various problems such as glaucoma, strokes and retinal detachments.
  • Advise: We will discuss the results of the various examinations and whether any action needs to be taken. This may include any of the following:
    - Discussing the most appropriate spectacle lenses 
    - Advising on how to self-treat certain conditions 
    - Discussing the most appropriate spectacle lenses 
    - Referring you for further checks
    - Or just letting you know that everything is healthy and no action is required
