Any bad eye habits can lead to a deepening of myopia, and the same goes for learning to draw. Learning to draw, if it is indoors, because the reading distance is too close, coupled with the use of the eye if a long time, it will lead to the speed of myopia development. However, if it is outdoor painting, it is relatively much better. This is because being outdoors increases the amount of time your eyes spend looking into the distance, which can slow down the rate of myopia development. So in the process of learning to paint, first of all, you should pay attention to control the time indoors, not more than two hours a day; if it is outdoors, this is better because it can slow down the development of myopia. So, no matter what the nature of the work or study, as long as you can make the eyes far and near to take into account, can slow down the development of myopia.
