Projections indicate that the global prevalence of myopia is expected to reach 39.80% in 2050. This signifies a substantial increase from historical levels, highlighting a growing worldwide public health concern.
The trend of increasing myopia prevalence has been consistently observed over recent decades. From 1990 to 2023, the pooled prevalence of myopia has shown a steady rise, demonstrating a clear upward trajectory that is projected to continue well into the mid-21st century.
Projected Myopia Prevalence Over Time
The following table summarizes the observed historical prevalence and future projections of myopia, providing a clear picture of this evolving global health challenge:
| Year | Pooled Prevalence of Myopia |
|---|---|
| 1990 | 24.32% (95% CI 15.23% to 33.40%) |
| 2023 | 35.81% (95% CI 31.70% to 39.91%) |
| 2040 | 36.59% (Projected) |
| 2050 | 39.80% (Projected) |
CI: Confidence Interval
Understanding the Increasing Trend
The significant rise in myopia prevalence, from approximately one-quarter of the population in 1990 to nearly two-fifths projected by 2050, underscores a dramatic shift in global vision health. This upward trend suggests a complex interplay of factors, often linked to changes in lifestyle, such as increased near-work activities (e.g., prolonged screen time) and reduced outdoor exposure.
This escalating prevalence of myopia, particularly high myopia, carries significant implications for public health systems worldwide. It is associated with a higher risk of serious eye conditions later in life, including retinal detachment, glaucoma, and myopic macular degeneration, which can lead to irreversible vision loss. Understanding and addressing the underlying causes of this increasing prevalence are crucial for mitigating its future impact on global vision health. The data provided reflects findings and projections based on comprehensive analyses.
