Daylight cuts risk for short-sightedness

8 May 2013

New healthcare research shows that children who play outside are less susceptible to short-sightedness and vision problems. Although the exact reason for this effect is still unclear, scientists believe it has something to do with high levels of dopamine in the eyeball, which has previously been linked to decreased risk of myopia, or short-sightedness.

Sunlight is believed to boost the body’s production of dopamine, a natural, feel good chemical in the bloodstream. Children who spend most of their days indoors at school may not generate as much dopamine. Researchers speculate that this results in elongation of the eyeball, a sign of worsening myopia. The study revealed that kids who play indoors, and therefore have the least access to sunlight, displayed eye growth of approximately 0.19 millimetres, while children who played outside had significantly less change.

Playing outdoors at a young age can also prevent more severe eye conditions, like glaucoma and retinal detachment. If you have inherited short-sightedness, or developed it from limited access to sunlight while you were young, treatments are available to correct serious disorders. Consider cataract removal surgery to eliminate cloudy obstructions of vision, or visit Edinburgh’s specialised eye centre, Spire Shawfair Park Hospital.
