A mother notes that her 6-year-old who is no longer attending school in person but on Zoom has blurred vision. She wonders if computer use is causing a need for glasses.Is there evidence linking both?
In today's journal club, we review a study by Wang et al looking at the prevalence of myopia in young children both pre and during the pandemic.
The study was a cross-sectional study in which the degree of myopia was measured in over 100,000 children over different years (pre-pandemic) and during the pandemic.
The data showed that:
- The prevalence of myopia was significantly higher in the COVID period for young children (4 times higher in the 6-year-old group)/li>
- The association was not statistically significant in older children
- Myopia prevalence, in general, rose as the patient’s age rose
