简要总结
VTI has an FDA cleared soft contact lens product. Its optical design creates an enhanced depth of focus (EDOF), which provides clear distance, intermediate, and near vision. This study is to quantify the enhanced depth of focus and visual impact.
详细描述
This study will develop defocus curves for Baseline best corrected spectacle refraction and then for the EDOF lens used in this study. A comparison of thge depth of focus for each condition will be made.
