[Visual contrast sensitivity in healthy Mexican population].
This paper presents a descriptive study of visual contrast sensitivity on 224 healthy Mexican individuals. Central tendency measures, Student's t test, as well as simple frequencies were the statistical tests used for data analysis. A format to evaluate visual contrast sensitivity adequate to healthy Mexican population is proposed, taking into account that the normal visual contrast sensitivity curve of Mexicans was found to be lower than the international standards.
