WHAT IS AN EYE TEST?

Once every two years you should have an eye examination however more regularly if advised by your optometrist.

1. Get to know you: Your optometrist will gain an understanding of your vision and your family’s health; this will help your optometrist understand your visual needs.

 

2. Establish a baseline: Many different tests may be performed to be able to make the best recommendations and give you the best advice. They will check your current vision on a letter chart, and also look at your previous glasses or contact lenses (if you have any) to establish a baseline.

Eye exams at National Pharmacies optical are bulk billed through Medicare however if additional tests or photography are required additional costs may be incurred.  The Optometrist will discuss this at your appointment.

TYPES OF EYE TESTS

The visual acuity test is a test where you read letters or identify shapes from a chart on a wall to determine the smallest size of letters you can see.

  1. Place the chart at a standard distance and observe while you cover one eye at a time and attempt to correctly identify letters or shapes.
  2. Visual Acuity is a measure of best corrected vision. Visual acuity is tested for both distance and near vision. The optometrist conducts a refraction test to determine the prescription required to give best corrected vision.

 

Astigmatism is a common condition vision condition that causes blurry vision, It occurs most commonly when the cornea (clear front of the eye)  is irregularly curved or less commonly the curvature of the lens inside the eye causing a “spread of light”.

Astigmatism frequently occurs with other vision conditions like myopia (short-sightedness) and hyperopia (long sightedness). Your optometrist will check for astigmatism, long sightedness and short-sightedness when checking your  prescription for glasses. The cause of astigmatism is unknown and can be hereditary.

Uncorrected Astigmatism can lead to headaches and/or eye discomfort. Prescribed glasses correct astigmatism and contact lenses can also often correct astigmatism.

Visual field tests are a way to check your peripheral vision also known as side vision.  A visual field test can determine if you have blind spots (called scotomas) in your vision and where they are. Visual field tests are undertaken for a variety of reasons with the most common being for glaucoma assessments.
