True or False: GP lenses are controlled by the fitter, whereas soft lenses are controlled by the companies.

• A. GP lenses controlled by patients
• B. GP lenses controlled by manufacturers
• C. False
• D. True

Answer: (D)

Gas-permeable lenses are custom-made and adjusted by the fitter based on the patient’s unique corneal shape and measurements, including base curve, diameter, edge design, and lens material. This means the clinician directly controls and refines the lens design during a fitting process to achieve the best vision, comfort, and ocular health. Soft lenses, on the other hand, come in predefined designs and parameters produced by lens manufacturers; the clinician selects the most suitable from those available options to fit the patient. So, the statement reflects that distinction: GP lenses are controlled by the fitter through customization, while soft lenses are controlled by the manufacturers through their product lines.
