Contact Lens Exam vs Glasses Exam: What’s the Difference?
If you wear glasses but are thinking about switching to contact lenses, you might wonder whether the eye test is the same. The short answer? No — a contact lens exam includes extra steps to make sure the lenses fit your eyes safely and comfortably.
To help you feel confident before your next optometrist visit, here’s a clear breakdown of the difference between a comprehensive eye exam and a contact lens exam in New Zealand.
What Is a Comprehensive Eye Exam?
A comprehensive eye exam checks the overall health of your eyes — not just your vision. Even if you don’t think you need glasses, regular eye checks are important for early detection of eye diseases such as glaucoma, cataracts, and macular degeneration.
During this exam, your optometrist will usually assess:
- Your medical and family history
- Vision needs based on work, study, and lifestyle
- Visual acuity (distance and near vision)
- How both eyes work together (binocular vision)
- Eye health using specialised tools
- Peripheral vision and neurological responses
- Eye pressure for glaucoma screening
If needed, they may also perform advanced tests like retinal imaging, corneal measurements, or visual field testing.
At the end, you may receive a glasses prescription — which will always differ from a contact lens prescription because glasses sit further from your eyes.
What Happens in a Contact Lens Exam?
A contact lens exam includes everything in a regular eye exam plus additional tests to ensure contacts are a safe option for you. Because lenses sit directly on your eyes, the fit must be precise.
Your optometrist will measure:
- Corneal curvature
- Pupil and iris size
- Tear film stability (to check for dry eye)
These measurements determine the right contact lens type, diameter, and base curve for your eyes.
You will then receive a contact lens prescription that specifies brand, fit, and power.
Your First Contact Lens Trial
If you’re new to contacts, your optometrist will give you a trial pair to wear for a few days or weeks. You’ll test how comfortable they feel and whether your vision stays clear throughout the day.
Make sure to note:
- Any dryness or irritation
- Blurry or fluctuating vision
- Redness or discomfort
If something feels off, stop wearing the lenses and return for a follow-up. It’s normal to try a couple of lens types before finding the perfect fit.
