The present article discusses the conceptualization of the term amblyopia, considering that current definitions that abound are limited to focus on very narrow aspects of what is encompassed in the term. Through an analytical review of the principal studies and documents related to the topic, the paper proceeds to unify the main ideas in order to develop a comprehensive concept of amblyopia. The importance of an inclusive conceptualization lies in its possible influence at the moment of approaching amblyopia clinically, since it could determine the elements that optometrists should focus on and use as measures of success in its treatment.
