Digital device use is associated with symptoms known as Computer Vision Syndrome (CVS), which may include eye strain, dryness, blurred vision, and headaches. Contact lens wearers may experience increased symptoms during prolonged near-focus activities. New contact lens designs have been developed to help reduce accommodative stress during digital device use; however, clinical evidence comparing their performance remains limited.
This randomized, double-masked, crossover study will compare two daily disposable stenfilcon A contact lenses. Each participant will wear both lens designs for five days each, separated by a three-day washout. Primary outcomes include subjective symptoms, visual acuity, range of clear vision, subjective accommodative performance, and objective accommodative response. The study is designed to provide evidence regarding the relative performance of the two lens designs in reducing visual discomfort and accommodative burden during digital device use.
