It&rsquo;s what we see as the white of the eye. Over the sclera lies the conjunctiva, a clear mucous membrane that prevents the eye from becoming dry. The conjunctiva is served by tiny <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/blood.html/">blood vessels</a>. If one of the blood vessels breaks open beneath the conjunctiva, it can cause a red patch to appear on the sclera.</p> <p>In most cases, a subconjunctival hemorrhage causes no pain, changes in vision, or discharge from the eye. Often, people won&rsquo;t know they have one until they look in the mirror. Subconjunctival hemorrhages can be caused by an <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/eye-injury.html/">injury</a> to the eye, violent coughing or sneezing, vomiting, or heavy lifting. Frequently, a subconjunctival hemorrhage will have no apparent cause.</p> <p>Subconjunctival hemorrhages require no treatment, although some people choose to use lubricating (rewetting) eye drops if they have a scratchy feeling in the affected eye.</p> <h3>Keep in Mind</h3> <p>Most subconjunctival hemorrhages cause no pain or problems and don&rsquo;t need treatment. The sclera will absorb the blood within 1-2 weeks. If the blood in the eye lasts longer than that or keeps coming back, it should be examined by a doctor as soon as possible.</p> <p><em>All A to Z dictionary entries are regularly reviewed by KidsHealth medical experts.</em></p>
