The correct spelling for the phrase "yellow vision" can be understood through the use of the International Phonetic Alphabet (IPA). "Yellow" is pronounced as "jɛləʊ" which is characterized by the /j/ sound at the beginning, indicating a "y" sound, followed by the short "e" sound, and an "l" sound. On the other hand, "vision" is pronounced as "vɪʒ(ə)n," characterized by the /ʒ/ sound, similar to the "s" sound in leisure, followed by a short "i" sound and finally an "n" sound.
Yellow vision refers to a condition or visual distortion in which an individual perceives their surroundings with a predominant yellow tint or hue. It is a subjective abnormality in color vision that alters the perception of colors, causing an overall yellowing effect. The phenomenon of yellow vision can manifest as an intense or subtle yellow cast that blankets the individual’s field of view.
Yellow vision can occur temporarily due to various factors, including prolonged exposure to bright yellow light sources such as the sun, glare from artificial lighting, or certain eye conditions. For instance, cataracts, a clouding of the lens in the eye, can cause yellow vision as the condition progresses. Additionally, yellow vision may be associated with medical conditions like jaundice, a liver disorder that causes a yellowing of the skin and eyes.
The distortion of colors in yellow vision can lead to difficulties in identifying objects accurately and perceiving the true hues of different colors. Individuals experiencing yellow vision may have challenges distinguishing between similar shades and may find it harder to determine color contrasts. It is important to note that yellow vision should be evaluated by an eye care professional, as it could be a symptom of an underlying medical condition or a side effect of medication. Treatment for yellow vision depends on its underlying cause, but it often involves addressing the root issue, such as treating the eye condition or liver disorder responsible for the yellow hue.

The word "yellow vision" does not have an established etymology as it appears to be a combination of two separate words: "yellow" and "vision".
"Yellow" originally derives from the Old English word "geolu", which is akin to the Proto-Germanic word "gelwaz". It has roots in the Proto-Indo-European base "*ghel-", meaning "to shine" or "bright". Over time, the word "yellow" came to refer to the color associated with gold, sunlight, and ripe fruit.
"Vision" originates from the Latin word "visio", ultimately deriving from the verb "vidēre", meaning "to see". The word entered into English through Old French, retaining its original meaning of the act or faculty of sight.
