If your glasses help you see clearly, you might assume the same prescription will work for contact lenses. However, contacts sit directly on your eyes instead of resting in frames in front of them. That difference matters for both vision and comfort. At Today's Vision in Laguna Niguel, we provide contact lens exams to help patients find lenses that fit their eyes and suit their everyday needs.

Why Glasses and Contact Lens Prescriptions Are Different

A glasses prescription measures the lens power needed to correct your vision at a distance from your eyes. Because contacts rest on the eye's surface, the required power may differ, especially with stronger prescriptions.

A contact lens prescription also includes fitting information that your glasses prescription does not provide. Details such as lens curvature, diameter, and the specific lens brand or design help ensure you receive the type that was evaluated for your eyes. Two lenses with similar powers may not fit or feel the same.

What Happens During a Contact Lens Exam?

Our goal is to evaluate more than how well you can read an eye chart. We consider your vision needs, eye health, and the way your eyes respond to contact lenses.

During your contact lens evaluation, we may assess:

·       Corneal shape and measurements: These help guide the selection of an appropriate lens fit.

·       Tear film and eye surface: Dryness or irritation may affect how comfortably you wear contacts.

·       Lens positioning and movement: We check how trial lenses sit and move when you blink.

·       Vision with the lenses: We assess clarity and make adjustments when needed.

We also review your eye health history, any previous contact lens problems, and the activities for which you want to wear contacts.

Choosing Contacts for Your Daily Routine

The right contact lenses depend on more than prescription strength. Some patients wear contacts for work or exercise, while others want an alternative to glasses for most of the day. We discuss factors such as your schedule, replacement preferences, and comfort to help identify suitable options.

Patients with astigmatism or changing near vision may need different lens designs. We explain available choices based on your exam findings rather than assuming one lens type works for everyone.

Why Follow-Up Visits Matter

A lens that gives clear vision initially must also fit properly and remain comfortable during normal use. Trial lenses may require adjustments, and a follow-up can help us evaluate your experience before finalizing your contact lens prescription. Even experienced wearers benefit from periodic evaluations because vision, tear quality, and eye health can change.

Contact lens exams are also an opportunity to review safe habits. Always wash and dry your hands before handling lenses, follow the recommended replacement and cleaning instructions, and keep lenses away from water. Do not sleep in contacts unless specifically prescribed for overnight wear.
