Yellow spot

Yellow Spot is a term that can refer to several different concepts in various fields, including biology, optometry, and entomology. This article will focus on the biological and optometric definitions, as these are the most commonly referenced in scientific literature.

Biology

In the field of biology, the term "yellow spot" is often used to refer to the macula lutea, a small area in the center of the retina in the human eye. The macula lutea is responsible for central, high-resolution color vision, which is necessary for tasks such as reading and driving.

Optometry

In optometry, the yellow spot is also referred to as the macula. This is the part of the eye where light is focused by the cornea and lens. The macula is packed with cone cells, which are photoreceptor cells that function best in relatively bright light and are capable of perceiving color.

Entomology

In entomology, a yellow spot can refer to a marking on the wing or body of an insect. The specifics of this marking can vary greatly depending on the species of insect.
