[3] However, variation occurs in the nature of this feature and the possession of "partial epicanthic folds" or "slight epicanthic folds" is noted in the relevant literature.
Epicanthic eye folds are believed to be an adaptation protecting the eye from overexposure to ultraviolet radiation, and is presumed to be a particular trait in archaic humans from eastern and southeast Asia. A cold-adaptive explanation for the epicanthic fold is today seen as outdated by some, as epicanthic folds appear in some African ...

Southern and eastern Africa are believed to originally have been populated by people akin to the San. Since that early time much of their range has been taken over by the Bantu.
With age, the bridge will narrow, and the epicanthic folds in the corner of the eyes will go away. This will cause the eyes to appear wider and thus not have the appearance of strabismus. To detect the difference between strabismus and pseudostrabismus, clinicians use a flashlight to shine into the child's eyes.
