Holistic-indicator model for predicting factors that generate visual health affections

This work is based on the General Systems Theory (GST), in that it mentions that the latter offers a better result when all of the parts that interrelate and make up a whole are studied. The objective of modeling a holistic indicator in the field of Optometry is to be able to provide information for evaluating the factors that affect vision, considering the interrelationship between each of these. There are diverse applications that alter visual health, among which the factors taken into consideration in the investigation are the following: cultural; economic; environmental, and technological factors. A mathematical model is designed that integrates the factors in order to provide an indicator in percentage and in global form to predict the state of visual health according to the harm caused by factors found in a population. The importance of the holistic-indicator model is that it comprises elements of the system (factors) that affect visual health.
