Vision Screening
A vision screening is a 10-minute assessment to identify subjects at high risk for eye disease or in need of a professional eye examination by conducting screening tests. A screening is not a diagnostic process and does not replace a comprehensive eye examination.
A vision screening is a set of simple vision tests performed to detect possible vision disorders. As these vision screening tests are not comprehensive, it is imperative to provide additional information, i.e. any vision impairments, previous eye injuries, or family history of vision conditions. We can then look for suggestive signs of possible conditions and recommend an appropriate course of action.
About the Vision Screening
Possible vision disorders that may be detected during a vision screening:
-
Amblyopia (lazy eye): Individuals with amblyopia usually have blurry vision in one eye.
-
Strabismus (crossed eyes): A condition where the eyes don't align correctly and point in different directions.
-
Myopia (nearsightedness): Distant objects appear blurry
-
Hyperopia (farsightedness): Objects in close range appear blurry
-
Astigmatism: Affects both distance vision and near vision
During a vision screening, we will assess:
-
Visual Acuity: To determine the clarity of your vision
-
Cover Test: To determine whether your eye muscles work well together
-
Pupillary reflex: Testing your eye's reaction to light and muscle coordination using charts.
-
Some vision screenings also test for colour deficiencies using the Ishihara Colour test

Signs that you may require one
Infants 3 months or older:
-
Not being able to make steady eye contact

Eyes that don't look properly aligned
Vision screening for infants will assess the baby’s ability to follow an object with his/her eyes, as well as how well the pupil (black center part of the eye) responds to bright light.
​
Older children and adults:
-
Blurry vision in the distance or close range
-
Eye strain
-
Headaches

Squinting
-
Closing or covering one eye
-
Watery eyes
-
Droopy eyelids
-
Redness in one or both eyes

Sensitivity to light
If a vision disorder is detected during your vision screening, you will be advised to book an appointment for a comprehensive eye test. Most vision problems and eye disorders are easily treated, especially if detected early.
