Contact Lens Exams

Contact lenses can provide convenient, effective vision correction without relying on glasses, but achieving clear and comfortable vision requires more than simply choosing a prescription. A comprehensive contact lens exam and professional fitting help determine which lens design, material, prescription, and wearing schedule are best suited to a patient’s eyes and lifestyle. This process becomes especially important for adults experiencing presbyopia, an age-related change in near focusing ability that can make reading, using a smartphone, or completing close-up tasks increasingly difficult.

At Macwan Eye Group, Dr. Rima Macwan provides contact lens exams and fittings in Marietta, GA, with personalized options for patients at different stages of life. For adults with presbyopia, multifocal contact lenses may provide a convenient way to achieve functional vision across multiple distances while reducing dependence on reading glasses. Because every patient’s eyes, prescription, visual demands, and comfort preferences are different, careful evaluation and customized fitting are essential to achieving the best possible contact lens experience.

Signs It May Be Time for a Contact Lens Evaluation

Vision and eye health can change over time, even for people who have successfully worn contact lenses for years. A contact lens exam is performed yearly for contact lens wearers and can help ensure vision remains consistent, lenses continue to feel comfortable, and the prescription continues to meet everyday visual demands.

Common signs that a contact lens exam or updated fitting may be beneficial include:

• Blurry or fluctuating vision while wearing contact lenses
• Difficulty reading small print or seeing a smartphone clearly
• Needing to hold reading material farther away
• Increasing dependence on reading glasses over contact lenses
• Eye dryness, irritation, or discomfort during lens wear
• Contact lenses that frequently shift or feel unstable
• Difficulty transitioning between near and distance tasks
• Reduced comfort after several hours of lens wear
• Headaches or eye strain during computer or close-up work
• A recent change in an eyeglass or contact lens prescription

Patients experiencing these concerns should have their vision and eye health evaluated rather than continuing to wear lenses that may no longer provide appropriate correction or fit.

Why a Professional Contact Lens Fitting Matters

A contact lens prescription contains information that differs from an eyeglass prescription because contact lenses sit directly on the surface of the eye. Proper fitting requires evaluation of the cornea, tear film, prescription, eye health, lens movement, and other factors that influence how safely and effectively a lens performs. A poorly fitting contact lens may cause discomfort, inconsistent vision, dryness, or irritation. In some cases, improper lens wear can contribute to more significant complications involving the cornea or ocular surface. Professional contact lens fittings help identify lenses that provide an appropriate relationship with the eye while supporting visual clarity, comfort, and long-term ocular health. For healthcare providers, comprehensive contact lens care is also an opportunity to identify conditions that may affect successful lens wear. Dry eye, allergies, corneal irregularities, medication-related changes, and other ocular conditions can influence lens selection and comfort. Evaluating these factors before prescribing contact lenses allows treatment recommendations to be tailored more precisely to each patient.

Multifocal Contact Lenses for Presbyopia

Presbyopia typically becomes noticeable around the early to mid-40s as the natural lens inside the eye gradually loses some of its ability to change focus between distances. Patients may notice that restaurant menus, text messages, labels, or computer screens are becoming harder to see clearly. While reading glasses are one solution, multifocal contact lenses can offer an alternative for patients who prefer less dependence on glasses. Multifocal contact lenses incorporate different focusing powers within the lens to support vision at near, intermediate, and farther distances. The visual system learns to use the appropriate areas of focus depending on what the patient is viewing. Modern multifocal lens designs are available in a variety of materials, replacement schedules, and prescription configurations, allowing fittings to be customized according to visual demands and eye health.

Successful multifocal contact lens fitting often requires greater customization than a standard single-vision lens fitting. Factors such as pupil size, prescription strength, dominant eye, reading demands, computer use, driving habits, and expectations can influence which design works best. Fine-tuning the prescription during follow-up visits can help create a more balanced visual experience for everyday activities.

How the Contact Lens Exam and Fitting Process Works

A detailed contact lens evaluation allows Dr. Rima Macwan to assess both vision and eye health before recommending an appropriate lens. The fitting process may involve several stages, particularly for patients transitioning into multifocal contact lenses.

• Comprehensive Vision and Eye Health Evaluation: The process begins with an examination of visual acuity, refractive error, eye health, and any conditions that could affect contact lens wear. Changes in prescription and symptoms such as dryness, irritation, or difficulty with near vision are also discussed.
• Corneal and Ocular Surface Assessment: The shape and condition of the cornea, tear film, and surrounding tissues are evaluated to determine which contact lens characteristics may provide the best fit. Adequate tear quality is especially important for maintaining comfortable lens wear.
• Lifestyle and Visual Needs Discussion: Daily activities play an important role in lens selection. Patients may be asked about computer use, reading, driving, sports, work environments, and how frequently they would like to wear contact lenses.
• Trial Lens Selection and Fitting: Based on examination findings, appropriate trial lenses may be placed on the eyes. The fit, movement, comfort, and quality of vision are then evaluated before finalizing a prescription.
• Multifocal Vision Assessment: For patients with presbyopia, near, intermediate, and distance vision are carefully assessed with multifocal lenses. Adjustments may be made to improve the balance between different viewing distances based on the patient’s most important daily visual tasks.
• Follow-Up and Prescription Refinement: Follow-up appointments provide an opportunity to evaluate real-world performance after the patient has worn the lenses in everyday settings. Lens power, design, material, or other fitting characteristics may be adjusted to improve clarity and comfort.

Protecting Eye Health While Wearing Contact Lenses

Safe contact lens habits are essential for maintaining healthy eyes. Patients should follow the recommended wearing and replacement schedule, use approved cleaning and disinfecting products when applicable, and avoid sleeping in lenses unless the specific lenses have been prescribed for overnight wear. Hands should always be washed and dried before inserting or removing contact lenses. Patients should also avoid exposing lenses to tap water, swimming pools, or hot tubs. Contact lens cases should be cleaned and replaced regularly according to professional recommendations.

Routine eye examinations remain important even when contact lenses feel comfortable and vision seems clear. Some eye health changes may develop without obvious symptoms, and regular evaluations allow the eyes, prescription, and lens fit to be monitored over time.

A Flexible Vision Solution for Presbyopia and Everyday Life

For many adults, presbyopia can make previously simple tasks increasingly dependent on reading glasses. Multifocal contact lenses offer another option by providing vision correction designed to support multiple viewing distances within a single lens. This may be particularly appealing for active adults who want greater freedom during work, exercise, social activities, travel, and other daily routines.

Adapting to multifocal contact lenses can take time, and expectations are an important part of the fitting process. Some patients adapt quickly, while others benefit from prescription refinements or trying a different multifocal design. The goal is not necessarily to create identical vision to what a patient experienced before presbyopia developed, but to achieve a practical balance of distance, intermediate, and near vision that supports everyday activities with less reliance on glasses. With personalized fitting, realistic expectations, and ongoing follow-up, contact lenses can continue to be a valuable vision correction option well into the presbyopic years.
