Abnormal symptoms when adapting to GP lens wear may include:

The correct choice highlights a common issue experienced by patients who may be struggling to adapt to gas permeable (GP) lenses. When patients remove their GP lenses, they expect their vision to return to normal within a few moments. If they experience a prolonged period, such as more than one hour, during which their vision remains unclear while wearing glasses, it suggests that the lenses may have disturbed the natural refractive state of the eye.

This symptom can indicate that the eye is not adapting properly to the GP lenses, potentially due to issues such as poor lens fit or surface irregularities affecting tear film stability and corneal health. The persistence of blurry vision could also be linked to adaptation difficulties, where the corneal epithelial cells may take time to return to their baseline state after lens removal.

While discomfort during lens wear, eye redness, and increased light sensitivity are related to GP lens wear and may be indicative of adaptation challenges, the prolonged clarity issue outlined in the correct answer reflects a more specific problem regarding how the contact lenses interact with the visual system and the eye's refractive properties.
