Droopy eyelids may be more than you think.

Ptosis refers to drooping of an upper eyelid of one or both eyes. The droop may be barely noticeable, or the lid can descend over the entire pupil. Ptosis happens in both children and adults, but usually occurs because of aging. Often patients choose to correct ptosis for cosmetic reasons, however in most cases, the drooping upper eyelid results in a reduction in the field of vision. Depending on how severely the lid droops, people with ptosis may have difficulty seeing. Sometimes people tilt their heads back to try to see under the lid or raise their eyebrows repeatedly to try to lift the eyelids. A furrowed forehead or a chin-up head position may indicate that someone is trying to see under their drooping lids. Eyelid drooping can make someone appear sleepy or tired as well as making the eyes fatigue easily, especially when reading.
