Parents are concerned. We overwhelmingly acknowledge that wearing glasses makes a huge impact to learning, about 40% of children are self-conscious with glasses or do not like wearing them. 3

Children are spending less time outdoors than before. Being outdoors, in the presence of sunlight has a protects the eyes against myopia 8. A child should be spending at least two hours a day outdoors.
The research shows that the increased effort required when reading material is held too close can increase the amount of myopia 10. The distance between your child’s knuckle and the elbow (the Harmon distance), is the same distance they should be holding a book.
It is vital to take breaks from lots of near work and look to the distance. This will relax the muscles used by the eyes to read. The muscles that turn the eyes in and those that focus the lens inside the eye. It’s the tiredness of these muscles that causes eye strain and drives more myopia. The easiest thing to remember is 20/20/20. Focus on an object at least 20 feet away for 20 seconds every 20 minutes. Taking a 10-15-minute break every 50 minutes also helps to improve concentration as well as helping muscles of the eye.
