Contact lenses may improve contrast sensitivity in high myopia, unlike spectacle lenses. Severe myopia shows reduced contrast sensitivity even with contact lenses, suggesting potential early retinal dysfunction.

Area of Science:

  • Ophthalmology
  • Vision Science
  • Optometry

Background:

  • Myopia, or nearsightedness, affects visual acuity.
  • Contrast sensitivity is crucial for visual function.
  • Optical correction methods include spectacle and contact lenses.

Purpose of the Study:

  • To measure contrast sensitivity function in myopia of varying degrees.
  • To compare contrast sensitivity with spectacle versus contact lens correction.

Main Methods:

  • 105 myopic eyes and 28 emmetropic eyes were studied.
  • Myopic eyes were categorized into low, medium, high, and severe myopia.
  • Spatial contrast sensitivity was measured using the OPTEC 2000 Contrast Sensitivity System.

Main Results:

  • Low and medium myopia showed no significant difference in contrast sensitivity compared to emmetropes.
  • High myopia corrected with spectacles showed reduced contrast sensitivity, but not with contact lenses.
  • Severe myopia showed reduced contrast sensitivity with both spectacle and contact lenses.

Conclusions:

  • Low and medium myopia likely have normal retinal function.
  • Contact lenses may improve contrast sensitivity in high myopia by reducing defocus.
  • Diminished contrast sensitivity in severe myopia may indicate early retinal dysfunction.
