What Actually Happens During a Comprehensive Eye Examination

Most people picture an eye test as reading letters off a chart and walking out with a spectacle number. A comprehensive eye examination goes well beyond that. It is a full health check of your eyes, and often the first place a wider health problem shows itself.

Here is what a thorough examination usually covers.

1. Your history and vision

We begin by understanding your symptoms, your general health, your medications and any family history of eye disease. Then we measure your visual acuity, that is, how clearly you see, both with and without correction.

2. Refraction: your spectacle number

This is where we fine-tune the exact lens power that gives you the sharpest, most comfortable vision. It is also how we pick up short-sightedness, long-sightedness, astigmatism and the age-related change called presbyopia.

3. Eye pressure

A quick, painless check of the pressure inside the eye is an important screen for glaucoma, a condition that can steal sight in silence. Read more about glaucoma here.

4. Examination of the front of the eye

Using a microscope called a slit lamp, we study the cornea, the lens and the other front structures, watching for cataract, dry eye and related conditions.

5. The dilated retina check

Often the most valuable part of the visit. Dilating drops widen your pupil so we can examine the retina and optic nerve at the back of the eye. This is how diabetic changes, macular degeneration and retinal weaknesses are caught, usually well before you would sense anything yourself. Your vision may stay blurry for a few hours afterwards, so it helps to bring sunglasses and to avoid driving straight after.

Why it matters even if you see fine

Many serious eye conditions cause no symptoms early on. A comprehensive examination is built to find them at that silent, treatable stage. You can read more about our eye examination service here.

An eye examination is not really about proving something is wrong. It is about confirming everything is right, and catching the rare exceptions while they are still easy to treat.
