A prospective randomized double-blind experimental design was used to compare the wearing clarity,comfort,clear visual perception and adaptation time of two aspherical astigmatic lenses with different designs.A questionnaire was used to assess the subjective evaluation of clarity,comfort,perception of clear vision,and adaptation time at the beginning of wearing and after 1 week of wearing the lens.The paired t-test was used to compare the objective visual acuity of the two groups,and the paired rank sum test was used to compare the subjective evaluation of the two groups.In the objective evaluation,the RCC(Reverse Curvature Correction)group had better visual discrimination ability,and the difference between the two groups was statistically significant.In the subjective evaluation,the scores of the RCC lenses were higher than those of the standard aspheric lenses,and the difference was statistically significant.In the evaluation of wearing comfort and glasses adaptation time,although the scores of RCC group were higher than those of standard aspheric group,the difference was not statistically significant.Compared with the traditional standard aspheric design,Reverse Curvature Correction design lenses can provide better wearing clarity,comfort and clear visual field while rapidly adjusting.
