PURPOSE: To compare the effects of blue light-filtering and non-blue light-filtering senofilcon A daily disposable contact lenses on color discrimination and contrast sensitivity in healthy young adults with myopia.
METHODS: This comparative study included 68 eyes of 34 myopic adults with best-corrected visual acuity of 0.0 logMAR. All participants were evaluated while wearing blue light-filtering and non-blue light-filtering senofilcon A daily disposable contact lenses. Color discrimination was assessed binocularly using the Farnsworth-Munsell 100 Hue test, with blue-yellow axis local error score (LES), red-green axis LES, and total error score (TES) recorded. Contrast sensitivity was evaluated monocularly using the Spaeth-Richman Contrast Sensitivity (SPARCS) test, and central, peripheral, and total SPARCS scores were compared between the two lens types.
RESULTS: No statistically significant differences were observed between blue light-filtering and non-blue light-filtering contact lenses in blue-yellow axis LES (p = 0.130), red-green axis LES (p = 0.275), or TES (p = 0.090). Contrast sensitivity scores were significantly higher with blue light-filtering lenses than with non-blue light-filtering lenses in the central area (p = 0.009), superotemporal area (p = 0.024), inferotemporal area (p = 0.013), and in the total SPARCS score (p = 0.016). No significant differences were found in the superonasal or inferonasal areas.
CONCLUSIONS: Blue light-filtering senofilcon A daily disposable contact lenses were associated with higher contrast sensitivity in central and selected peripheral visual field regions, without a measurable effect on color discrimination.
