As we get older, the lower eyelids sometimes start to droop away from the eyeball. Drooping is the result of reduced muscle tone in the muscles that control the eyelids.
If your lower eyelids droop outward, away from the eye (ectropion), they may no longer be able to protect your eyes, and your eyes may become dry and irritated. If your eyelids turn inward (entropion), forcing the lashes onto the eye, this also may cause irritation and possible damage.
Also, drooping eyelids can prevent tears from draining normally, so tears may run down your cheeks. Excessive tearing can also be a sign of increased sensitivity to light or wind, an eye infection, or a blocked tear duct.
There is no home treatment for drooping eyelids. But surgery can sometimes help.
