Article courtesy: Points de Vue – Essilor
The prevalence of myopia and high myopia is on the rise across the world. Recent work from the Brien Holden Vision Institute esti­mates that by 2050, five billion (50%) people will be myopic, one billion (10%) highly myopic. This may have important implications for planning comprehensive eye care services, including refractive ser­vices such as spectacles and contact lenses for correcting and slowing myopia progression. Optical and environmental interventions can help in preventing and managing high myopia related ocular complications and reduce the burden of myopia.
