5 Key Takeaways

• 1

  Lens awareness can result from mechanical lens-lid interaction, a failing lens surface, or an ocular surface problem exposed by the lens.

• 2

  TABS—timing, asymmetry, blink, and stop—helps direct the initial slit-lamp evaluation but does not replace the full workup.

• 3

  Immediate, constant discomfort suggests a mechanical cause, whereas discomfort that builds over the day points toward a surface problem.

• 4

  Unilateral lens awareness warrants evaluation for a lens defect, deposit, conjunctival elevation, asymmetric fit, corneal irregularity, or lid difference.

• 5

  Relief with blinking suggests a tear-film problem, discomfort during blinking suggests lid interaction, and persistent rawness after lens removal suggests surface disease.
