To investigate the effects of daily wear opaquely tinted hydrogel soft contact lenses on contrast sensitivity functions, as measured using the Pelli-Robson chart viewed at 1 meter. Methods. Contrast sensitivity was measured in 48 healthy individuals before and 6 hours after soft contact lens wear. Twenty-four subjects used clear soft contact lenses and 24 used tinted soft contact lenses. Results. The contrast sensitivity scores were significantly decreased monocularly and binocularly (P= 0.000 and P= 0.002, respectively) in the colored contact lens group whereas there were no significant changes in the clear contact lens group (P = 0.317 and P = 0.317, respectively). Conclusions. Color-tinted contact lenses were associated with a reduction of contrast sensitivity function. Therefore, those who wear colored contact lenses should be informed about the possible consequences of tinted contact lens wearing. © 2003 Contact Lens Association of Ophthalmologists, Inc.en10.1097/00140068-200301000-00012info:eu-repo/semantics/openAccessContrast sensitivityOpaquely tinted hydrogel soft contact lensArticle291484912769157Q2
