Dermatochalasis, more commonly known as droopy or baggy eyelids, can affect both upper and lower eyelids. This condition may affect peripheral vision, as well as make eyes look and feel tired.
Blepharoptosis is a condition that causes the upper eyelid to droop. The eyelid can actually fall into your field of vision, and make it difficult to see.
Entropion is a condition where the lower eyelid and lashes turn inward. Entropion is commonly due to the relaxation of eyelid tissues over time.
Ectropion is an abnormal lower eyelid that turns outward and no longer touches the eye. This can happen to adults, as the eyelid relaxes over time.
Blepharitis is chronic redness, irritation, and flaking of the eyelids, which can lead to lid infection and irritation of the eye.
