PARACHROMA Meaning and
Definition
-
Parachroma is a term used in the field of optics to describe a type of color vision deficiency or anomaly. It refers to a condition where an individual has an impaired ability to distinguish specific colors, particularly shades within the red and green spectrum. People with parachroma may have difficulty perceiving differences between certain colors, making it challenging for them to accurately identify or differentiate between hues that appear similar to individuals with normal color vision.
Parachroma is often considered a form of red-green color blindness, but it is distinct from other types of color blindness, such as protanopia or deuteranopia. While individuals with parachroma may experience similar challenges in perceiving certain colors, the underlying mechanisms and causes may differ.
The condition can be congenital, meaning it is present from birth, or it can also be acquired later in life due to certain medical conditions, medications, or eye diseases. Parachroma can vary in severity, with some individuals having a more mild impairment and others having a more significant impact on their color perception.
The term "parachroma" is derived from the Greek words "para," meaning alongside or beside, and "chroma," meaning color. It emphasizes the altered or abnormal color perception experienced by individuals with this condition. Researchers and eye-care professionals utilize parachroma as a classification to better understand and diagnose various color vision deficiencies, thus aiding in the development of targeted approaches to manage and address the specific challenges associated with this condition.

The root "chroma" also comes from Greek, meaning "color".
