RedEyed

Redeyed is a term used in multiple contexts to denote redness of the eyes or to serve as a proper name or alias in some cases. As an adjective, it is commonly written red-eyed, describing eyes that appear red due to dilation of the conjunctival blood vessels. The form Redeyed may appear in branding, usernames, or fictional names where capitalization or concatenation varies.

In medical contexts, a red eye is a common symptom with many potential causes. Irritation from smoke, dust, or contact lens wear; ocular allergies; dry eye; and infectious conjunctivitis are among the most frequent non-emergency causes. More serious conditions, such as corneal ulcers, uveitis, or acute glaucoma, can also present with eye redness and may require urgent evaluation. Diagnosis relies on history and eye examination, with attention to accompanying symptoms such as pain, vision changes, discharge, or light sensitivity. Treatment depends on the underlying cause and can range from lubricating eye drops and antihistamines to antibiotic or antiviral therapy, or referral to an ophthalmologist for persistent or severe cases.

In photography, the term red-eye refers to an artifact where camera flash reflects off the retina, producing a red appearance in the photographed subjects. Red-eye reduction features, improved lighting, or post-processing can mitigate this effect.

As a proper noun, Redeyed can refer to individuals, characters, or brands that use the name; such usages are specific to particular works or persons and have separate articles if notable. See also red eye, conjunctivitis, and red-eye reduction.
