What term describes the condition of having sand in the eyes?

The condition where someone feels as though they have sand in their eyes is most accurately described by the term "corneal abrasion." A corneal abrasion refers to a scratch or injury to the cornea, the transparent front part of the eye, which can occur when small particles like sand or dust come into contact with it. This condition can cause discomfort, redness, excessive tearing, and a sensation similar to having something gritty in the eye.

In contrast, eye strain pertains to discomfort and fatigue in the eyes resulting from prolonged use, usually due to screens or reading. Arc flash refers to a specific electrical hazard that can occur in high-voltage environments and is unrelated to eye conditions. While the term "injury" is broad and could encompass a corneal abrasion, it does not specify the type of injury, making it less precise than the specific medical terminology associated with the sensation of sand in the eyes.
