研究成果
If X chrome color contact lenses are implemented during child’s learning period, it will eliminate many of the academic challenges that are faced with color coded learning and teaching materials and improve their quality for many recreational activities.
研究不足
The study was limited to a small sample size of 10 patients and focused only on inherited color vision defects, excluding acquired color vision defects and those due to diabetes or any sort of ocular pathology.
1：Experimental Design and Method Selection:
A pilot, cross sectional study was performed in the tertiary eye care centre during the period of one year. Functional vision like Visual Acuity, Contrast Sensitivity, Stereopsis and color vision of 10 existing x chrome soft contact lenses users were analyzed with and without lenses.
2：Sample Selection and Data Sources:
A total no. of 10 patients was enrolled in the study with informed consent. Patients having inherited color vision defect, using x chrome color contact lens, and absence of any ocular or systemic pathology were included into the study.
3：List of Experimental Equipment and Materials:
Visual acuity was measured using Log mar chart, Contrast Sensitivity was measured using Pelli Robson Contrast Sensitivity chart, Stereopsis was measured using Titmus fly test, Color vision was assessed with ishihara plates and Fransworth Munsell-D-15 test.
4：Experimental Procedures and Operational Workflow:
Visual function was assessed with and without lens in all 10 patients.
5：Data Analysis Methods:
Statistical analysis was performed using paired t test due to its normal distribution curve with SPSS software version 20.
