Contrast Sensitivity: A Test Of Visual Performance In Adapted Contact Lens Wearers.

Contrast sensitivity testing reveals visual deficits not detected by standard acuity tests, providing a more sensitive measure of visual perfonnance. Sine wave contrast sensitivity functions were examined for spectacle and contact lens correction in well adapted lens wearers. Over the past decades, dozens of articles have been published that investigated the visual perfonnance of soft contact lens wearers. Despite the large number of publications on this topic, there has been no consensus yet, on how contact lenses affect the visual perfonnance in well adapted lens wearers. My article focuses on the effect of visual perfonnance among well adapted contact lens wearers. I have included both soft lens and hard contact wearers and compared their visual perfonnance with their habitual glasses.
