Which symptom is commonly associated with arc eye?

Arc eye, also known as welder's flash or photokeratitis, results from the exposure of the cornea to ultraviolet (UV) light, which often occurs during welding or prolonged exposure to sunlight without proper eye protection. The condition can lead to a number of symptoms due to damage caused to the corneal surface.

Blurred vision is a common symptom of arc eye because the cornea becomes inflamed and irritated as a result of the UV exposure. The inflammation can disrupt the smooth surface of the cornea, which is essential for maintaining clear vision. The swelling and potential damage to the corneal epithelium can lead to distortion in how light is refracted, resulting in blurred or hazy vision.

Other symptoms associated with arc eye may include redness, light sensitivity (photophobia), tearing, and a gritty or painful sensation in the eyes, but blurred vision is particularly indicative as it directly relates to the impact of UV exposure on visual acuity.
