Summary

The goal of this comparative clinical trial is to assess the effectiveness of DAILIES TOTAL1 Toric Contact Lenses compared to Spherical Equivalent Contact Lenses in improving the functional vision of astigmatic patients, with a particular focus on Asian individuals who frequently use digital devices.

The main questions it aims to answer are:

How do DAILIES TOTAL1 Toric Contact Lenses affect the quality of vision in daily activities, especially when using digital screens, compared to Spherical Equivalent Contact Lenses?

What is the level of comfort and overall satisfaction among participants using DAILIES TOTAL1 Toric Contact Lenses versus those using Spherical Equivalent Contact Lenses?

Participants will be asked to wear both types of contact lenses for a specified period. During this time, they will perform various tasks involving digital screens. Their vision quality and comfort levels will be monitored and recorded. They will also be asked to report their satisfaction with each type of lens and any differences in their experience with screen use.

Interventions

DIAGNOSTIC_TEST

Visual acuity test

Assess near high-contrast visual acuity (40cm) using EyeChart PRO on an iPad. Use the MNREAD app to measure: Reading Acuity: Smallest font size read without errors. Critical Print Size: Smallest font size for peak reading speed. Maximum Reading Speed: Time to read comfortable font size, in words per minute. Reading Accessibility Index: Single metric summarizing visual access to print. Assess near visual function with the Near Activity Visual Questionnaire. Evaluate distance visual acuity, both high and low contrast, using logMAR and the E-ETDRS (NIDEK SC-2000).
