A contact lens fitting is a professional evaluation to choose and verify the safest contact lens type, size, and prescription for your eyes. It goes beyond a standard vision test because contacts must match your eye shape and tear film to stay comfortable and deliver clear vision. The fitting process also helps reduce the risk of irritation and infection by confirming proper lens movement and eye health.
What to Expect:
- Eye measurements and health checks, including corneal measurements and an evaluation of dryness and the eye surface.
- Lens selection based on your needs, such as single vision, toric for astigmatism, or multifocal options, plus fit values like base curve (BC) and diameter (DIA).
- A trial lens assessment to confirm comfort, vision, lens centering, and movement, since these affect clarity and safety.
- Wear-and-care training, including how to insert and remove lenses, cleaning steps for reusable lenses, and safe wear time.
- Follow-up as needed to fine-tune the fit or prescription, because small adjustments can improve comfort and stable vision.
Contact lens fitting helps ensure the lens prescription and fit match your eyes so you can wear contacts comfortably and safely.
