Summary

The proposed study will address this gap by comparing the efficacy of two novel stenfilcon A contact lens designs in alleviating accommodative burden associated with digital device usage.

The primary outcomes are measured with the following:

* Computer vision syndrome questionnaire
* Binocular logMar (H/Lo contrast) visual acuity at 6M and 40cm.
* Binocular range of clear vision
* Subjective assessment of accommodation
* Objective assessment of accommodation Subjects will be randomly assigned to wear one contact lens design for 5 days. Then crossed over tot he opposing design after a three day washout period, and again asked to wear the lens for 5 days.

Conditions
