Red spots or visible blood vessels in the eye are typically associated with subconjunctival hemorrhage, which occurs when a small blood vessel beneath the conjunctiva ruptures, causing blood to pool on the white part of the eye. While the red patch may appear concerning, it is usually painless, does not affect vision, and often resolves spontaneously, similar to a bruise on the skin. According to Verywell Health, the body gradually reabsorbs this blood, allowing patients to continue normal activities during recovery.

The red spot may initially be bright red, sometimes spreading slightly more within the first 24-48 hours. Subsequently, it fades, turning brown or yellow before disappearing entirely. This process typically lasts about three weeks.

Avoid rubbing eyes and straining

Although no specific treatment is needed, it is advisable to limit factors that could cause further damage or re-bleeding. Avoid rubbing or applying strong pressure to the eyes. If participating in sports or working in an occupation with a risk of eye injury, protective eyewear should be used.

Activities that increase pressure in the head, such as coughing, sneezing, vomiting, or straining during bowel movements, can also be associated with ruptured blood vessels. Individuals with chronic constipation should address the underlying cause and may increase dietary fiber as appropriate. Contact lens wearers should pay attention to proper insertion, removal, and cleaning to minimize irritation or damage to the eye surface.

Do not stop anticoagulants without medical advice

Some people experience subconjunctival hemorrhage linked to medications that increase bleeding risk, such as anticoagulants or aspirin. However, individuals using these medications should not arbitrarily stop or change their dosage if they notice red spots in their eyes.

If the condition recurs, a doctor can evaluate related factors such as blood pressure, bleeding disorders, or underlying medical conditions to determine the cause and appropriate course of action.

Persistent red spots or accompanying eye pain require examination

Most cases are not concerning and resolve on their own. However, medical attention should be sought if the red spot does not disappear after a few weeks, appears repeatedly, or has an unknown cause. In particular, accompanying eye pain or vision loss are signs that require early examination, as these symptoms may not be consistent with a simple subconjunctival hemorrhage and warrant ruling out other eye injuries. According to WebMD, if subconjunctival hemorrhage recurs, an ophthalmologist should also evaluate it to find the cause and reduce the risk of recurrence.

Overall, for simple red spots on the white of the eye that are painless and do not affect vision, time is usually the most important factor for eye recovery. Patients do not need to seek ways to quickly dissolve the blood but should avoid rubbing their eyes, limit the risk of injury, and monitor the progression.
