Eye Testing
Eye Tests
Regular eye tests are essential for checking your vision, detecting early signs of eye disease, and monitoring changes in your eyesight over time.
Many eye conditions develop slowly and may not cause noticeable symptoms at first, which is why routine eye examinations are recommended even if
you feel your vision is normal.
During an eye test, your vision will be assessed for distance and close work, and your eye health will be examined using specialised equipment.
If any problems are identified, you may be given a new glasses or contact lens prescription, advised on lifestyle changes, or referred to an
ophthalmologist (eye specialist) for further assessment and treatment.
Signs You May Need an Eye Test
You should consider booking an eye test if you notice any of the following:
- Blurred or double vision
- Difficulty reading or seeing clearly at distance
- Headaches, especially after screen use or close work
- Eye strain, tired or sore eyes
- Needing to hold books or screens closer or further away than before
- Squinting to see more clearly
- Sensitivity to light or glare
- Floaters, flashes of light, or changes in your visual field

Why Are Eye Tests Important?
Eye tests are not only for updating your glasses or contact lens prescription. They also play a key role in detecting:
- Short-sightedness (myopia), long-sightedness (hyperopia), and astigmatism
- Age-related focusing problems (presbyopia)
- Cataracts
- Glaucoma
- Macular degeneration
- Diabetic eye disease and high blood pressure changes in the eye
Some general health problems, such as diabetes, high blood pressure, and high cholesterol, can also be picked up during an eye examination,
making regular tests an important part of overall health screening.
What Happens During an Eye Test?
A routine eye test is usually quick and comfortable. It may include:
- Vision check: Reading letters on a chart to assess distance and near vision.
- Refraction test: Using different lenses to find the best prescription for glasses or contact lenses.
- Eye health examination: Using lights and lenses to examine the front and back of the eye, including the retina and optic nerve.
- Pressure test: Measuring eye pressure to screen for glaucoma (if required).
- Pupil dilation (if needed): Eye drops to widen the pupils for a more detailed view of the retina.
How Often Should You Have an Eye Test?
As a general guide, most adults should have an eye test every 1–2 years. You may need more frequent checks if you:
- Already wear glasses or contact lenses
- Have diabetes, high blood pressure, or other medical conditions affecting the eyes
- Have a family history of glaucoma or other eye diseases
- Experience any sudden changes in vision or eye discomfort
Important:
If you suddenly lose vision, experience a curtain or shadow over your sight, see flashes of light with many new floaters, or have severe eye pain,
seek urgent medical attention immediately. These may be signs of a serious eye emergency.
