dryness is a common term for a feeling of insufficient moisture on the eye surface. In eye care, it often describes symptoms linked to tear film instability or reduced tear production. People may notice burning, grittiness, fluctuating vision, or contact lens discomfort. Clinicians use the term dryness as a symptom description and as a cue to evaluate the ocular surface.
