Abstract: “The present invention provides a new method and system for preventing myopia acquisition in children and young adults. There is strong evidence that near work might lead to myopia. The axial length of a human eye is growing in the first 25 years of life. There is experimental evidence for feed-back loops to control this growth. Prolonged near-work might interfere with these feed-back loops in a way that the axial length growth accelerates to provide perfect near vision-myopia. Using reading glasses in normal-sighted children and young adults prevents interference of prolonged near-work with axial length growth, hence preventing environmentally driven myopia acquisition.
