Why a Contact Lens Exam Is Separate from a Regular Eye Exam
A standard eye examination produces a glasses prescription. Contact lenses require all of that information plus additional measurements a regular exam does not capture:
- Corneal curvature measurements: Contact lenses sit directly on the cornea. The base curve and diameter must match the shape of your eye precisely, or the lens will move excessively, feel uncomfortable, or reduce oxygen flow to the cornea.
- Tear film assessment: Dry or unstable tear film affects how contact lenses perform. Your optometrist evaluates your tear quality to recommend the most compatible lens materials.
- Corneal health evaluation: Wearing contact lenses places demands on the cornea. Your optometrist checks for signs of corneal thinning, scarring, or prior issues that would affect lens selection.
- Contact lens prescription differences: A contact lens prescription includes your lens brand, base curve, diameter, and power. A glasses prescription does not contain these details.
What to Expect During a Contact Lens Exam in Edmonton
The additional steps beyond your regular eye exam in Edmonton include corneal topography or keratometry, tear film evaluation using slit lamp biomicroscopy, trial lens fitting with your optometrist observing lens position and movement, a wearing period where you try the lenses, and a follow-up assessment before the prescription is finalized.
Which Type of Contact Lens Is Right for You?
- Daily disposable soft lenses: The most convenient option. You wear them once and discard them. No lens care required.
- Monthly or bi-weekly soft lenses: More economical for daily wearers. Require nightly cleaning and storage.
- Toric lenses for astigmatism: Designed to correct irregular corneal curvature. Fitting these requires careful assessment to ensure stability and clear vision.
- Multifocal contact lenses: For patients over forty who need both distance and near correction, multifocal lenses are an alternative to reading glasses.
- Rigid gas-permeable (RGP) lenses: Useful for patients with irregular corneas or keratoconus. They provide sharp vision and excellent oxygen transmission.

How Often Do You Need a Contact Lens Exam?
Most Edmonton optometrists recommend an annual contact lens assessment as part of your regular eye exam schedule. Even if your prescription has not changed, your corneal health, tear film, and lens fit should be reviewed each year. Wearing contact lenses on an outdated prescription increases your risk of complications.
