What this trial studies
Children with mild-to-moderate digital eye strain (CVS-Q score 6–18) are enrolled and receive either an oral astaxanthin capsule or a matching placebo while being followed for changes in symptoms. Symptom severity is tracked with validated questionnaires (CVS-Q) and eye examinations to monitor signs such as dry eye and accommodative strain. The protocol excludes children with severe DES, contact lens use, ocular motility or binocular disorders, recent ocular procedures, systemic diseases affecting the eye, and use of carotenoid/retinol supplements. Safety and tolerability of the oral astaxanthin product are monitored throughout the treatment period.
Who should consider this trial
Good fit: Children who have digital eye strain with CVS-Q scores between 6 and 18 and who do not meet any exclusion criteria (for example, no contact lens use, no diagnosed binocular/accommodative disorders, and no relevant systemic illnesses) are ideal candidates.
Not a fit: Children with severe digital eye strain (CVS-Q ≥19), contact lens wearers, those with ocular motility or accommodative/binocular vision disorders, or those taking carotenoid/retinol supplements are excluded and unlikely to benefit from this protocol.
Why it matters
Potential benefit: If successful, the treatment could reduce the frequency and severity of screen-related eye discomfort in children, improving comfort during device use.
How similar studies have performed: Some adult and preclinical research suggests astaxanthin's antioxidant and anti-inflammatory properties may help ocular symptoms, but randomized pediatric data are limited.
