Why does the eye gets puffy?

Puffy or swollen eyes can be caused by fluid retention, stress, allergies, hormone changes, and other factors. Crying is often accompanied by swollen eyes because the tiny glands in the eyelids that produce tears become inflamed from overactivity.

Other times we get puffy eyes after sleeping. This can be caused by too much sodium in the diet, which causes water retention. Puffy eyes can also be caused by lack of sleep or excessive alcohol intake.
