The planet is losing sight due to smartphones: the main issue is darkness, not light
The entire world is facing widespread vision deterioration linked to smartphones, but the problem is not the light from screens—it is the fact that people use devices in dark environments. When looking at close objects in dim light, pupils constrict to improve clarity, allowing less light to reach the retina. The brain adapts to this as normal, causing irreversible eye modifications. By 2050, half of the world’s population may become myopic due to this smartphone- and social media-related phenomenon.
To prevent myopia development, experts recommend simple measures: using bright overhead lighting when reading or working, rather than just a bedside lamp; every 20 minutes, looking at an object 6 meters away for 20 seconds to relieve ciliary muscle spasm; and spending at least one hour outdoors daily, as sunlight positively influences eye health.
Following these guidelines could reduce the risk of widespread vision loss in the future and help preserve eye health despite increasing smartphone and digital device usage.
