Eye Screening

Half of all blindness or eye disorders can be prevented or cured. A vision screening can help identify people who are at risk for eye disease.

Young children with vision problems often do not know that the way they see the world is not the way everyone sees it. Yet vision problems affect one in 20 pre-schoolers. They also affect one in four school children. Without early detection and treatment, children's vision problems can lead to:

  • Permanent vision loss
  • Learning difficulties

Any changes in the appearance of your eyes or vision should be investigated further. Some examples include:

  • Unusual trouble adjusting to dark rooms;
  • Difficulty focusing on near or distant objects;
  • Squinting or blinking due to unusual sensitivity to light or glare;
  • Change in colour of iris;
  • Red-rimmed, encrusted or swollen lids;
  • Recurrent pain in or around eyes;
  • Double vision;
  • Dark spot at the centre of viewing;
  • Lines and edges appear distorted or wavy;
  • Excess tearing or "watery eyes";
  • Dry eyes with itching or burning; and
  • Seeing spots, ghost-like images.

The following may be indications of potentially serious problems that might require emergency medical attention:

  • Sudden loss of vision in one eye;
  • Sudden hazy or blurred vision;
  • Flashes of light or black spots;
  • Halos or rainbows around light;
  • Curtain-like blotting out of vision; and
  • Loss of peripheral (side) vision.

If you notice any signs of potential eye problems, see an eye doctor for a complete eye exam. Even if you have no signs, regular eye exams are recommended-especially for those with some chronic health conditions such as diabetes and high blood pressure. Early detection and treatment can be the key to preventing sight loss.

Below are a few online eye tests

Amsler Eye Test for Central Vision

An Amsler grid is a useful tool for monitoring your central visual field. It is an important way to detect early and sometimes subtle visual changes in a variety of macular diseases such as age-related macular degeneration and diabetic macular edema... Read More

Ishihara Test for Colour Blindness

Colour blindness is an inaccurate term for a lack of perceptual sensitivity to certain colours. Absolute colour blindness is almost unknown. There are three types of colour receptors in our eyes, red, green and blue. We also have black and white receptors. They are more sensitive than the colour receptors, that is why we have poor colour perception in the dark.

Visual Acuity Test

Visual acuity measures our ability to see small detailed black objects on a white background, such as printed text... Read More
