Our vision is important and unfortunately eye health is often neglected. A comprehensive Eye examination includes, checking the Eye pressure, front and back parts of the eye and also testing the health and function of the eye nerves. These are some of the test done in our clinic.

Visual Acuity Test:


  • How well you are able to see at distance as well as to check if there are any changes in vision.
  • The test is carried out one eye at a time,
  • where you are required to read the standardized chart (Snellen Chart) held 6 metres away.
  • Smaller letters would indicate a better distance vision while a larger letter would indicate poorer vision.
  • Normally, one would be able to see the 6/6 (20/20) line. However, when vision is worse than 6/12, a pinhole would be used to check if vision is able to be improved with spectacle correction or it can be due to other eye problems (e.g. cataract).


  • The Near VA Test is carried out with a near chart, to test how well you are able to see at near with both eyes, with N5 being the smallest line.


Auto-refraction is an objective testing of vision using an auto-refractor machine. It is a rough estimation of eye refractive power, whereas a full refraction is a comprehensive manual testing of vision.

A refraction is usually performed if vision is bad. Vision < 6/6 can be due to various reasons:

  • Myopia (Short-sightedness)
  • Hyperopia (Far-sightedness)
  • Astigmatism (Uneven eye surface)
  • Presbyopia (unable to focus when reading due to ageing)

Or eye conditions affecting the back part of the eye (e.g. Macular Degeneration, Retinal Detachment)

Colour Vision:

  • The Colour Vision Deficiency (CVD) Test is used to determine if you have any colour blindness.
  • The Ishihara Colour Vision Test, is a booklet with 15 plates consisting dots of different colours, brightness and sizes. Individuals with normal colour vision would be able to see one or two numbers on the plate, while a colour blind individual would be seeing a different number or no numbers at all.
  • There are a few types of CVDs, mainly:






ACQUIRED (due to other factors)


Intraocular pressure:

  • There are many ways to measure our eye pressure. One of them is to use the Tono-pen, where by a pen-like machine is used to touch lightly on the surface of the cornea.

Stereopsis/Depth of Perception Testing:

  • The Titmus Fly Stereo Vision Test is a form of Depth of perception testing (3D vision). This is important for children during eye screenings as it is able to indicate whether your child has any diseases indicated below:
  • Amblyopia (Lazy Eye)
  • Strabismus (Eye Squint)
  • Suppression during binocular vision
  • The test consists of 3D graphs (circles, fly and objects) whereby individuals are required to view through polaroid spectacles with their vision corrections on.

Schirmer’s Tear Test:

  • Schirmer’s Tear Test is a test to assess the eye’s tear production. It is usually performed to diagnose dry eyes as a healthy tear film is important for vision.

Cover Test:

  • The cover test is used to determine any presence of eye turn or eye squinting (deviation of the eye). The angle of deviation is also measured using a prism bar.

Visual Field Test:

  • The visual field test is used to check the area of vision of each individual eye, while looking straight ahead (peripheral vision) as well as the eye’s sensitivity to light.
  • It is a test of the function of the eye nerve.
  • It is a common test used to diagnose and monitor glaucoma
  • Glaucoma affects the peripheral vision first.
  • It may also detect other conditions like stroke or brain tumours.


  • The Optical Coherence Tomography is a non-invasive, advance retinal eye imaging test which shows the layers of the retina.
  • It may scan the central retina as well as the optic nerve ( eye nerve).
  • Abnormality in thickness of the retina or eye nerve may indicate diseases like Retinopathy, Macular diseases and Glaucoma
