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.

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.

Inclusion Criteria:

• Suitable and able to wear contact lenses
• Normal best corrected vision (20/25 or better)
• Need reading add +2.00 or stronger

Exclusion Criteria:

• Pre-existing ocular condition that would contraindicating lens wear
