Contact Lens Fittings Specialist

How does a contact lens fitting differ from a fitting for eyeglasses?

Unlike eyeglasses that rest in front of the eyes, contact lenses are placed directly on the surface of the eyes, and proper measurements and other assessments are required to ensure they fit comfortably and provide the proper correction for the needs of each patient. In addition to a standard comprehensive eye exam or medical eye exam, a contact lens fitting includes evaluations and measurements of the surface portion of the center of your eye, or the cornea, which is located over the pupil. Contact lenses rest on the cornea, and very precise measurements are needed to ensure lenses fit properly in order to avoid irritating the cornea, which can become damaged over time when lenses are not properly fitted. In addition, the pupil size and location will be measured, and the tear film will be evaluated to look for the presence of dry eye, which can have an impact on contact lens wear. In addition, once the lenses are ready to be picked up, an actual fitting will be performed to assess how well the lens fits the eye and to evaluate the movement of the lens during blinking and when the eyes are moved up and down and from side to side. Vision will also be briefly assessed once the lenses are in place.

What are specialty contact lenses?

In addition to contact lenses that correct for refractive vision issues like nearsightedness (myopia), farsightedness (hyperopia) and astigmatism, there are special lenses that can be used to address specific vision needs, including some differences in the eye anatomy. The comprehensive eye exam prior to contact lens fitting will determine if specialty lenses are necessary for optimal vision.

What are trial lenses?

Trial contact lenses will be ordered after the initial exam and fitting to ensure the prescription and other measurements are correct. These trial lenses are worn for a brief period – usually a week or two – and are evaluated for comfort and vision correction so any adjustments can be made before ordering the final lenses.
