Snowblind, (/ˈsnəʊˌblaɪnd/), is a compound word formed by combining "snow" and "blind". The spelling of the word follows the standard English spelling rules, as it is pronounced as it is spelled. American and British English phonetic transcription for this word is different. The American Phonetic Alphabet indicates the "o" sound as /oʊ/ while British English Phonemic Alphabet indicates "o" sound as /əʊ/. "Snowblind" refers to the condition where a person temporarily loses their vision due to the reflection of sunlight on snow or ice.
Snowblind is an adjective that describes a temporary vision impairment caused by intense exposure to white or reflective surfaces, such as a snowfield or a bright icy landscape. The term is rooted in the combination of the words "snow" and "blind," which suggests a loss of visual perception due to the overwhelming brightness and glare associated with snow or ice.
When a person becomes snowblind, their eyes are affected by the excessive amount of ultraviolet (UV) radiation reflected off the snow or ice. As a result, the cornea, the transparent outer layer of the eye, is irritated and inflamed, causing symptoms like eye pain, redness, tearing, and a sensation of grittiness. These symptoms typically tend to appear a few hours after exposure and may last for one to two days.
The condition is often experienced by individuals engaging in outdoor activities in snowy regions without proper eye protection, such as sunglasses or goggles that filter out harmful UV rays. Snowblindness can significantly impair vision, making it difficult to perform everyday tasks and even causing temporary blindness in severe cases. However, the symptoms usually subside as the eyes recover from the excessive UV exposure, and vision returns to normal.
To prevent snowblindness, it is crucial to wear appropriate eyewear with UV protection, shield the eyes from the intense sunlight reflecting off snow, and limit exposure time in bright snowy conditions.
The term "snowblind" originated from the combination of two words: "snow" and "blind".
The word "snow" can be traced back to the Old English word "snaw", which had the same meaning. It ultimately derives from the Proto-Germanic word "*snaiwaz", which is thought to have originated from the Proto-Indo-European root "*snieg-", meaning "snow".
The word "blind" comes from Middle English "blind" and Old English "blind", both meaning "unable to see". It is related to the Proto-Germanic word "*blindaz".
When combined, "snowblind" refers to a visual impairment or temporary loss of vision caused by the intense reflection or glare of sunlight on snow or ice. The term is commonly used to describe a condition where someone's eyes are affected by the bright light and white hue of the snow, causing a temporary form of blindness or reduced vision.
