Eye Slit

The palpebral fissure can be compared to a gap in a doorway that allows light and air to enter a room. The palpebral fissure is an important part of our body because it allows us to see and interact with the world around us.

The palpebral fissure consists of two parts: upper and lower. The upper part of the palpebral fissure is formed by the eyelids, which protect the eyes from dust and dirt. The lower part of the palpebral fissure is located between the eye and nose. It allows the eyes to move and focus on objects.

In addition, the palpebral fissure plays an important role in the thermoregulation of our body. When we are in cold climates, our palpebral fissure closes to keep the body warm. Conversely, when we are in a warm climate, the palpebral fissure opens to allow heat to escape from the body.

It is important to remember that the palpebral fissure must be open throughout the day to ensure the normal functioning of our eyes. However, if the palpebral fissure is not open enough, it can lead to various vision problems such as dry eyes, eye fatigue, and even headaches. Therefore, it is important to monitor the condition of the palpebral fissure and, if necessary, take measures to open it.
