Refraction determines your exact eyeglass or contact lens prescription by measuring how your eyes focus light (sphere, cylinder, axis). It is the foundation for crisp, comfortable vision correction.

When it is needed: Blurry vision, eyestrain, night‑glare, or prescription updates; pre‑/post‑surgery baselines; specialty fits for astigmatism and presbyopia.

FAQs

  • An eye exam is a full eye health check.
  • Refraction specifically tests your vision and provides you with a glasses /contact lens prescription.

No, contacts require a separate prescription due to sitting directly onto the eye.

  • A contact lens fitting ensures your lenses are the correct size, shape, and material for your eyes. It includes measurements of your cornea, tear film evaluation, and a trial pair to check comfort and vision.
  • contact lens fittings usually take 30–60 minutes, depending on your eye shape, prescription, and whether you are new to contacts. Follow-up visits may be needed to fine-tune the fit.
