The “burden” of myopia
Preventing myopia is possible, at least partially, thanks to a healthier lifestyle and spending more time outdoors from childhood
More than 1.4 billion people in the world are short-sighted and their numbers seem destined to increase: half of the world’s population is likely to become short-sighted by 2050 . These are the numbers quoted by Ophthalmology in its editorial of March 2018. It is estimated that today, approximately one third (33.6%) of Europeans aged 50 to 54 years are affected by myopia.
Can something be done to prevent myopia or at least slow down its progression? The answer is: yes. In fact, excluding genetic factors, we can work on improving lifestyles: "There is strong evidence that greater time spent outdoors is associated with a lower incidence of myopia".
It is also necessary to promote "exercise, fitness, reduced screen time, and weight control". In short, more open air and less pixels... Such a lifestyle should be followed from childhood, as exposure to natural light helps prevent the excessive lengthening of the eyeball.
The authors of the article - all Americans  - write that the risks of major complications incurred by people with high myopia, range from retinal detachment to glaucoma, and include cataracts, choroidal neovascularization, optic neuritis, staphyloma and myopic macular degeneration.
