RESEARCH

Background: The use of smartphone is rising rapidly globally. Recent data show that 95% of US teenagers and 68% of Australian children own or have access to a smartphone and most exceed the daily recommended screen time guidelines set by World Health Organisation. Chronic use of digital devices can induce ocular symptoms (including chronic pain), cause visual fatigue, adversely impact blinking, disrupt the tear film and cause dry eye. This threat to ocular surface health is not well studied in children, and the ocular surface in children is not well characterised. Only a handful of studies have measured ocular symptoms in children and although children appear to report less symptoms of dry eye in comparison to adults, this may be due to poor understanding and use of dry eye questionnaires which have been developed for use in adults

Aim: To characterise ocular surface of children including blinking, and to examine the impact of smartphone use on the ocular surface homeostasis in children.

Methods: This research aim will be explored in four individual/parallel studies. Study 1 focused on a systematic review and meta-analysis to characterise ocular surface homeostasis (symptoms, tear film, ocular surface, blinking) in children. Study 2 (cross-sectional, n=60) will validate Six dry eye symptom questionnaires (Symptoms Assessment in Dry Eye (SANDE), Ocular Surface Disease Index (OSDI), Numerical Rating Scale (NRS), Ocular Comfort Index (OCI), Dry Eye Questionnaire 5 (DEQ-5), and Instant Ocular Symptom Survey (IOSS)), to determine the feasibility of use and reliability in children aged 6-15 years. Study 3 (randomised cross-over intervention, n=24) will explore real time blinking (using wearable eye tracking headset) under stimulated habitual patterns of smartphone use and other visual and non-visual conditions (reading, conversation, walking). Study 4 (interventional, n=45) will examine the impact of smartphone use on ocular surface homeostasis (symptoms, tear film, ocular surface, blink parameters) in children.

The outcome of this research will shed light on blink dynamics, the effects of smartphone on eyes of children and help develop reliable assessment tools to diagnose dry eye symptoms among children. The findings of this research will inform evidence-based guidelines to eye care practitioners on safe screen time for eye health. Parents, guardians, and teachers will be better informed on the safe screen time for children.
