Prevention is indeed the basis of medicine, and in the case of myopia we have several strategies to at least prevent or slow down the progression of myopia once it has established. Measures to control myopia are grouped into 3 categories according to their characteristics:

1. Optical control: adequate correction.
2. Influence on lifestyle: limiting time spent on close-up tasks and increasing outdoor activities.
3. Pharmacological and therapeutic control: in cases where a high risk of myopic progression is detected. In this section we include preventive treatments with diluted atropine eye drops for at least one year.

Taking care of visual health in the first years of life is a task shared by pediatricians and ophthalmologists. In a healthy child, with normal psychomotor development, the first check-up by an ophthalmology specialist is recommended between 3 and 4 years of age.

Starting with the first visit at the age of 3 years, without taking into account other aspects that may influence the future development of refractive errors such as family history, it would be advisable to have a review every 2 years until reaching adulthood. This would ensure early detection of myopia, adequate correction of it and, of course, monitoring and control of said refractive error. If there is a family history, an annual review would be most appropriate.
