In which scenario are GP lenses particularly challenging?

• B. Sleeping
• C. Sitting in front of a screen
• D. Playing sports

Answer: (D)

Gas-permeable lenses rely on a stable tear film and the rigid lens sitting steadily on the cornea to deliver consistently sharp vision. In a calm, static setting, the lens can stay put with minimal disruption, so vision remains stable. When you’re playing sports, however, the eye is moving rapidly, blinking frequently, and exposed to wind, sweat, dust, and potential minor impacts. These factors can cause the lens to shift or lose lubrication, leading to momentary blur and discomfort. Debris can also get underneath the edge, increasing irritation or the feeling that the lens isn’t centered properly. All of this makes maintaining clear, reliable vision much more challenging during sports than during quieter activities.
