Which characteristic is not typically associated with Cortical Visual Impairment?

Cortical Visual Impairment (CVI) primarily arises from brain damage affecting visual processing rather than issues with the eyes themselves. One notable characteristic of CVI is the variability in visual responses, meaning that individuals may demonstrate a range of visual awareness and inconsistent reactions to visual stimuli. This can manifest as fluctuating ability to see, where sometimes vision might be clearer, and at other times, it may be less so.

Visual field defects can also be associated with CVI due to the involvement of brain pathways that process visual information. These defects occur when specific areas of the brain responsible for processing certain visual fields are damaged.

However, the characteristic that does not align with CVI is the necessity for corrective lenses. Unlike refractive errors, which can be corrected with glasses or contact lenses, the visual issues stemming from CVI are not resolved through optical means. This distinction is crucial for understanding how CVI differs from other forms of visual impairment that do require corrective lenses for optimal vision enhancement.
