Blepharitis, or eyelid inflammation, one of the most common problems, is characterized by erythematous eyelids with accumulation of debris along the eyelid margin. Malignant eyelid tumors may be associated with lash loss and erosion of normal eyelid structures.
Quarter Moon, captured by NASA astronauts. Image credit: NASA. You can have a first quarter moon, when the Moon is halfway between a new moon and full moon. A new moon occurs when the Moon is directly in between the Sun and the Earth. From that perspective, the illuminated Moon is facing away from the Earth.
The Quarter Moon is the Same as a Half Moon. The quarter Moon is also called a âhalf Moonâ because it looks like the Moon is only half litâon one side of the Moon during the first quarter and on the other side during the third quarter because the Moon is on the other side of Earth. The third quarter usually happens around day 22 (twenty-two). A half Moon has something to offer: Only a half Moon aims its terminator, the day-night line that is home to all the juicy detail, straight at us.
