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.
Moon phases depend on the position of both the Sun and Moon with respect to the Earth. The 4 primary phases of the Moon are: new, first quarter, full and third quarter.
Answer: The terms first quarter and last quarter refer not to the moon's apparent shape but to the points in time within the lunar month. We recognize four main phases, and therefore divide the lunar cycle into 4 parts, or quarters. Starting with new moon, then first quarter, full, then last quarter, then back to new.
