A fold on the upper eyelid
The epicanthal fold is a genetic distinction that is most prevalent among East Asians. It is a fold of skin that covers the inner corner of the eye and is most prominent along the upper eyelid. This fold is often celebrated in Asian cultures and is considered a sign of beauty.
Epicanthal fold in other cultures
Epicanthal folds can also be found in other cultures, such as among Native Americans and some African populations. However, it is most common among East Asians. The fold is typically more pronounced in children and can become less noticeable as they get older.
Epicanthal fold and its function
The function of the epicanthal fold is not fully understood. Some researchers believe that it may have evolved to protect the eyes from the sun and wind. Others believe that it may be a vestigial feature that has no real function.
