This morning twitter gifted me with a fascinating study published this year in Nature magazine entitled, “The myopia boom: Short-sightedness is reaching epidemic proportions. Some scientists think they have found a reason why.”
The study reports alarming and very dramatic increases in myopia (the scientific term for near-sightedness/short-sightedness) worldwide with Asian myopia rates now well over 90% compared to 10-20% just sixty years ago.
Intriguing in the analysis is the finding that time spent outside correlates with myopia with the highest risk for developing myopia among children and adolescents spending the greatest amount of time indoors and the lowest risk experienced by those spending the most time out of doors. Activity level was surprisingly not a factor, but light exposure is.
Our eyes need light, especially unfiltered, natural sunlight in order to be healthy. We need to get out of doors and play. And on nice days we need to move our classrooms out of doors, something I am pleased to say my teachers did from time to time, especially in springtime.
So get outside — even when the weather is a less than ideal — and help preserve and protect your sight. You deserve nothing less than healthy eyes.
