RESUMO
PURPOSE: The opaque contact lens (OCL) market is profitable and expanding. This pilot study sought to identify OCL color preferences among women of three ethnic groups, African American (A), white (W), and Hispanic Americans (H). METHODS: Sixty-three brown-eyed female subjects (19 A; 22 W; 22 H), 18 to 35 years of age, with uncorrected near visual accuity of at least 20/50 were recruited. Each subject was presented with OCLs of three different color pattern designs in each of four colors (blue, green, gray, and hazel). The subjects viewed their appearance in a mirror while wearing each lens. Once all lenses had been observed, the subjects chose their lens color preference. RESULTS: Using the nonparametric Kruskal-Wallis test, an ethnic preference was shown for all but the gray contact lenses. In group A 47.4% rated the hazel lens as their first choice whereas 0% chose the blue lens. In contrast, 45.5% of group C chose the blue lens over the other colors but did not favor the hazel lens, which was their first choice only 4.5% of the time. Group H demonstrated the most diversity in color preference, however, 36.4% chose green as their overall lenscolor preference. CONCLUSIONS: Distinct differences exist in OCL color preferences among the three ethnic groups studied. Improved understanding of this ethnic difference could increase the efficiency of the trial lens process while possibly decreasing inventory costs when one ethnic group dominates a practice patient base.
