Understanding a Full Eye Check: What to Expect

20 January, 2025 | 1:51 AM

A full eye check is more than just reading letters off a chart. It’s a comprehensive assessment of your vision and overall eye health, tailored to uncover potential issues before they become serious. For anyone who has never had one or is unsure about the process, understanding what happens during a full eye check can ease concerns and highlight its importance.

Why a Full Eye Check Matters

Your eyes are not just windows to the world; they’re also indicators of your general health. Many systemic conditions, like diabetes or high blood pressure, can first be detected through an eye examination. A full eye check does more than test your vision—it looks for signs of eye diseases, evaluates how well your eyes work together, and ensures that you’re seeing as clearly as possible.

Skipping regular eye checks might mean missing early signs of conditions that could lead to vision loss if untreated. The earlier issues are found, the better the outcome. Whether you’re young, old, or somewhere in between, a full eye check is vital for keeping your eyes—and your health—on track.

Best Time for an Eye Exam

What Happens During a Full Eye Check?

When you arrive for your appointment, you’ll be greeted by a friendly team ready to guide you through the process. A full eye check generally involves several key steps, each focusing on a different aspect of your vision and eye health.

  1. Understanding Your History

The first part of a full eye check involves a conversation. Your optometrist will ask about:

  • Any vision changes you’ve noticed.
  • Current health conditions, like diabetes or high blood pressure.
  • Medications you’re taking.
  • Your family’s eye health history.

This step helps the optometrist identify any risks or specific areas to focus on during the check.

  1. Visual Acuity Test

This is the part most people are familiar with—reading letters from a chart. This test determines how well you can see at various distances and helps identify issues like nearsightedness, farsightedness, or astigmatism.

  1. Checking Eye Movements

Your optometrist will test how well your eyes work together by tracking an object as it moves. Smooth, coordinated movements indicate good muscle control, while any misalignment could point to issues like strabismus or convergence insufficiency.

  1. Refraction Test

Using a device called a phoropter, the optometrist will determine your prescription for glasses or contact lenses. You’ll be asked which lens options make letters clearer or blurrier—this process ensures pinpoint accuracy for your prescription.

  1. Eye Pressure Test

A painless test measures the pressure inside your eyes. High pressure could be an early sign of glaucoma, a condition that damages the optic nerve and can lead to vision loss if untreated.

  1. Examining the Front of Your Eyes

Using a slit lamp, the optometrist will examine the outer structures of your eye, including the cornea, iris, and lens. This test can identify conditions like cataracts or dry eye syndrome.

  1. Retinal Examination

Drops may be used to dilate your pupils, allowing the optometrist to examine the back of your eyes, including the retina and optic nerve. This test is crucial for detecting signs of diabetic retinopathy, macular degeneration, or retinal detachment.

  1. Specialised Tests (If Needed)

Depending on your age, symptoms, or medical history, additional tests may be performed. For example:

  • Visual field test: Detects blind spots in your peripheral vision.
  • Colour vision test: Identifies colour-blindness.
  • OCT scan: Provides detailed images of your retina and optic nerve.

How Long Does a Full Eye Check Take?

How Long Does a Full Eye Check Take?

A typical full eye check takes about 30–45 minutes. If your eyes need dilation, it may take a little longer. The process is thorough but designed to ensure every aspect of your vision and eye health is assessed.

How Often Should You Get a Full Eye Check?

The frequency of full eye checks depends on your age, health, and risk factors:

  • Children: At least once before starting school and every two years afterward.
  • Adults under 65: Every two years unless otherwise advised.
  • Adults over 65: Annually, as the risk of eye diseases like glaucoma or cataracts increases with age.
  • People with health conditions: If you have diabetes or a family history of eye disease, your optometrist may recommend more frequent checks.

What Can a Full Eye Check Reveal?

Regular eye checks can detect:

  • Refractive errors: Such as nearsightedness, farsightedness, or astigmatism.
  • Eye diseases: Including glaucoma, cataracts, and macular degeneration.
  • Systemic conditions: Like diabetes, high blood pressure, or high cholesterol.

Tips to Make the Most of Your Appointment

  • Bring your glasses, sunglasses, or contact lenses.
  • Have a list of your medications ready.
  • Note any vision changes, like difficulty seeing at night or frequent headaches.
  • Ask questions—your optometrist is there to help.

Protecting Your Vision

Protecting Your Vision: What Happens Next?

Once your full eye check is complete, your optometrist will explain the results and provide recommendations. If you need glasses, you’ll get a prescription tailored to your needs. If any issues are detected, a treatment or management plan will be discussed. This might include regular monitoring, lifestyle changes, or referrals for further care.

FAQs

1. Do eye checks hurt?

No, full eye checks are painless. Some tests might feel slightly unusual, like the air puff for measuring eye pressure, but they’re completely safe.

If your pupils are dilated, your vision might be blurry for a few hours. It’s best to avoid driving until the effects wear off.

In many cases, eye checks are bulk billed in Australia for Medicare cardholders. Speak with your optometrist about fees if you’re unsure.

Even if you have perfect vision, regular checks are essential. Many eye conditions show no symptoms in their early stages.
