Impact

We estimate that myopia and high myopia will show a significant increase in prevalence globally, affecting nearly 5 billion people and 1 billion people, respectively, by 2050. These have important implications for planning comprehensive eye care services, including refractive services such as spectacles and managing and preventing myopic-related ocular complications and vision loss among people with high myopia.

Potential Consequences


Uncorrected refractive error (URE) will increase substantially

Cataract and Glaucoma-Fraction attributable to myopia likely to increase

Blindness and vision impairment due to myopic macular degeneration (MMD) and myopia retinopathy in adults will increase substantially

Resources: Need for refractive and specialist services (spectacles, contact lenses) for managing myopia-related complications will increase

IMPACT ON LEARNING AND EDUCATION

Early intervention and detection in children with myopia is the key to reducing the impact of myopia on their long term ocular health and improving their future lives. Short term benefits of addressing myopia includes improved visual function4 that can positively impact learning outcomes and has flow on effects on economic productivity.
