Step-by-step explanation:
The fundamental fitting concept for Proclear Multifocal and XR/Biofinity multifocal lenses by CooperVision is balancing near and distance vision needs option C).
The fundamental fitting concept for Proclear Multifocal and XR/Biofinity multifocal lenses by CooperVision is C) Balancing near and distance vision needs. These lenses are designed to provide clear vision at all distances for individuals with presbyopia, addressing the loss of accommodation ability due to the stiffening of the lens with age.
The power of the eye can change to accommodate objects at various distances, thus multifocal lenses like Proclear and Biofinity aim to aid in this adjustment process for both nearsightedness (myopia) and farsightedness (hyperopia). These lenses are designed to provide clear vision for both near and distance objects, allowing individuals with presbyopia to see clearly at different distances without having to constantly switch between different pairs of glasses.
