Interventions

• Stenfilcon A contact lens designs with and without Digital Boost technology that incorporate a 0.3D add power into the lens — DEVICE
  The MyDay stenfilcon A contact lens is a spherical lens. The MyDay Energys stenfilcon A contact lens has Digital Boost technology that incorporate 0.3D ADD power into the lens.

Study Details

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.
