Summary

Many people using computers or digital devices (e.g., smartphones or tablets) experience eyestrain and this has been called Computer Vision Syndrome (CVS) or Digital Eye Strain. Spectacle lens manufacturers have designed products to alleviate the symptoms of CVS. One such product, designed by Hoya (SYNC III), aims to do this by providing accommodative support. The present study is a parallel group double-masked RCT of people with CVS. One group will receive Hoya SYNC III lenses and the other (control) group single vision (SV) lenses. The main aims are to evaluate whether:

1. binocular vision and accommodative functions at baseline can predict participants who benefit from SYNC III design lenses;
2. the wearing of SYNC III design lenses is associated with any changes in binocular and accommodative functions at 6 months of follow-up;
3. the wearing of lenses with accommodative support reduce the symptoms of computer vision syndrome at 3 and 6 months of follow-up.

Participants will be examined three times: at baseline and three and six months after receiving their lenses. The group who receive control lenses will be provided with SYNC III lenses at the end of the six month trial for a brief one week follow-up evaluation.
