Can Google Help Your Nearsightedness? A Google Trend Analysis of Public Interest in Myopic Progression

Purpose: To explore public interest in myopia progression and management and to correlate these trends to available treatments.

Methods: Keywords were chosen for interest in myopia overall and those signifying interest in myopia treatments. Treatment options were separated into four main categories: atropine, glasses, contact lenses, and orthokeratology. Search terms were queried across ten years of Google Trends data and the relative search volume was analyzed to quantify the change in search volume over time.

Results: A positive linear trend over time was present for all myopia interest keywords except "nearsighted" (p = 0.074) and "near work myopia" (p = 0.086). Interest in the four myopia treatment categories included in this study also displayed a significant positive trend over time. There is also a statistically significant positive correlation between all four treatment options and four of the seven categories of population interest, "myopia control", "myopia", "myopia progression", and "screen time myopia".

Conclusion: This study demonstrates the utility of GT to correlate public interest in myopia treatments over time. All treatment terms had statistically significant linear search volume growth over a ten-year period. The positive correlation between interest in myopia as a health problem and available treatments supports existing evidence that GT can track rising public health concerns and corresponding treatment-seeking behaviors.
