Redness in your eye can result from a number of things, from allergies to pinkeye or simply being really tired. One common cause is episcleritis, a condition that isn’t harmful and often goes away on its own.

What triggers episcleritis?

There is no apparent cause, but it can be associated with an underlying systemic inflammatory or rheumatologic condition such as rosacea, lupus or rheumatoid arthritis. Typical symptoms include generalized or local redness of the eyes that may be accompanied by mild soreness or discomfort but no visual problems.

How long does episcleritis last for?

Most isolated episodes of episcleritis resolve completely over 2-3 weeks. Those cases that are associated with systemic disease can take on a more prolonged course with multiple recurrences.
