A surprising number of people put off booking an eye test simply because they don't know what it involves. Will it hurt? Will their eyes be blurry for hours after? These are completely understandable questions, and the good news is that a comprehensive eye test is painless, takes about 25–30 minutes, and involves no injections or anything remotely invasive.
If you've been putting off your eye test, or you're bringing a child in for the first time, here's exactly what happens, step by step, no surprises.
It's More Than Just Reading a Letter Chart
Most people picture an eye test as a few minutes squinting at letters on a wall. In reality, a thorough eye examination at Prime Optometrists Auburn assesses far more than just whether you need glasses. We're looking at the health of the entire visual system, from the surface of the eye to the back of the retina, and screening for conditions that can affect your general health, not just your sight.
What Gets Checked in a Comprehensive Eye Test
1. Visual Acuity
The letter chart measures how clearly you can see at a standard distance (usually 6 metres). You'll read progressively smaller lines of letters, typically with each eye separately and then both together. This gives a baseline measure of your clarity of vision and identifies whether a prescription is required.
2. Refraction (Your Prescription)
We determine your precise optical prescription using a process called refraction. You'll look through a phoropter (the large instrument with multiple lenses) and compare lens combinations, “Which is clearer, one or two?”, to identify whether you have short-sightedness (myopia), long-sightedness (hyperopia), astigmatism, or presbyopia.
3. Eye Pressure
Intraocular pressure (IOP) is measured as part of glaucoma screening. High pressure inside the eye can damage the optic nerve over time, often without any symptoms until significant vision loss has already occurred. This is measured either with a gentle puff of air or a contact probe after a numbing drop. Neither method causes lasting discomfort.
4. Slit Lamp Examination
The slit lamp is a specialised microscope that illuminates the front of your eye in extraordinary detail. We examine the cornea, conjunctiva, eyelids, crystalline lens, and tear film quality, checking for scratches, infection, inflammation, early cataracts, and meibomian gland dysfunction. You rest your chin on a support and look straight ahead; the instrument doesn't touch your eye.
5. Retinal Examination
The back of the eye, the retina, optic nerve, macula, and retinal blood vessels, is examined using specialised lenses. The retina is unique in medicine: it's the only place in the body where blood vessels can be directly observed without any invasive procedure. Changes in the retinal vasculature can indicate diabetes, high blood pressure, and in some cases multiple sclerosis, this is why eye tests matter even when you feel your vision is fine.
6. Binocular Vision Assessment
We assess how your eyes work together as a pair, eye alignment, convergence, tracking, and depth perception. Problems with binocular vision are a common cause of headaches, eye strain, and reading difficulties, and are frequently missed when only visual acuity is tested. This is particularly important in children, where binocular vision issues can affect learning and development.
7. OCT Imaging (At Prime Optometrists)
At Prime Optometrists Auburn, we have a Topcon Maestro OCT, a hospital-grade retinal imaging device that produces detailed, cross-sectional scans of the retina and optic nerve. OCT imaging can detect glaucomatous changes, macular degeneration, and diabetic retinal damage years before they cause any visual symptoms. It takes about five seconds per eye, involves no contact with your eye, and creates a permanent baseline record for future comparison.
Eye Tests Can Detect More Than Eye Problems
An eye examination can reveal signs of conditions that have nothing to do with vision:
- Diabetes: Retinal vessel changes and haemorrhages are among the earliest visible signs
- High blood pressure: Arteriovenous nicking and vessel narrowing can be seen
- Multiple sclerosis: Optic neuritis is often the first presenting symptom of MS
- Raised intracranial pressure: Optic disc swelling is a critical finding that warrants immediate referral
This is why routine eye tests matter even when your vision seems perfectly fine. A bulk billed eye test at Prime Optometrists costs nothing with a valid Medicare card.
What to Bring to Your Eye Test
- Your Medicare card, essential for bulk billing
- Your health fund card, if you have optical extras cover
- Your current glasses, even if you feel the prescription is outdated
- A list of any medications you take, some drugs affect the eyes and tear film
- Contact lenses or your glasses as backup, if you wear contacts, bring them on the day
Will My Pupils Be Dilated?
Pupil dilation is performed when clinically indicated, for example, if we want a clearer view of a retinal finding, or for younger patients requiring an accurate refraction. Dilation drops cause the pupil to remain enlarged for 2–4 hours, making near vision blurry and causing light sensitivity. You shouldn't drive immediately after dilation. We'll always let you know in advance so you can arrange transport if needed. Our OCT imaging can provide detailed retinal information without dilation in many cases.
