Palpebral Fissure (Eye Opening / Interpalpebral Space)
The palpebral fissure is the opening between your upper and lower eyelids—the part of your eye that's visible when your eyes are open. This opening varies in size between people and can change with age, emotion, or medical conditions. A healthy palpebral fissure allows good vision and proper tear coverage.
