Key Points

Examine whether mild sensory discomfort during contact lens wear serves an adaptive physiological role by initiating protective parainflammatory pathways.
Synthesized observational and clinical findings on ocular surface and cellular responses to contact lens wear.
Evaluated physiological adaptations recorded through in vivo confocal microscopy and immune cell tracking.
Mild mechanical and sensory stress from contact lenses drives controlled, low-grade parainflammation rather than destructive chronic inflammation.
Sustained parainflammatory signaling enhances local immune surveillance, preserving corneal epithelial barrier function and protecting against infection.

Implication

Narrative review reveals how low-grade sensory discomfort triggers protective parainflammation during contact lens wear, indicating improved resilience against ocular surface complications.

Abstract

Our understanding of the ocular response to contact lens wear has grown exponentially over the past 30 years,1 fuelled by the availability of sophisticated imaging technology such as in vivo confoc...
