A subconjunctival hemorrhage (SCH) appears as a bright red patch on the white part of the eye, caused by a broken blood vessel beneath the conjunctiva. While its appearance can be alarming, an SCH is typically harmless and resolves without intervention. This article clarifies whether wearing contact lenses is advisable with an SCH.
Understanding Subconjunctival Hemorrhage
A subconjunctival hemorrhage results from the rupture of small blood vessels within the conjunctiva, causing blood to leak. Common activities like coughing, sneezing, vomiting, or straining can lead to this by briefly increasing pressure. Minor eye trauma, vigorous rubbing, or even contact lens insertion/removal can also contribute.
The condition presents as a red spot, usually without pain, swelling, or vision changes, though a mild scratchy sensation may occur. Most resolve on their own within one to two weeks, with larger spots taking longer. As the blood reabsorbs, the red patch may change color, similar to a bruise fading, often turning yellowish before disappearing completely.
Wearing Contacts with Subconjunctival Hemorrhage
Wearing contact lenses is not recommended when experiencing a subconjunctival hemorrhage. The eye is already in a compromised state, and a contact lens can introduce additional irritation or discomfort. Lenses also elevate the risk of infection, as the eye’s surface is more vulnerable to bacteria that can accumulate on them, especially if proper hygiene is not maintained. Furthermore, the lens can hinder the natural healing process by interfering with the eye’s delicate surface as it works to reabsorb the leaked blood.
Managing Your Eye During Recovery
While an SCH is healing, wearing eyeglasses is a safe alternative to contact lenses, allowing the eye to recover without foreign objects. To alleviate mild dryness or irritation, preservative-free artificial tears can be used, though these will not expedite redness resolution. Avoid rubbing the affected eye, as this can worsen bleeding or delay healing.
Maintain good eye hygiene, washing hands thoroughly before touching eyes. Contact lens wear should only be resumed once redness has completely cleared, the eye feels normal, and any irritation has subsided. If uncertain about resuming contact lens use, consult an eye care professional.
When to Consult a Doctor
While most subconjunctival hemorrhages are harmless and resolve spontaneously, certain symptoms warrant immediate medical attention. If the hemorrhage is accompanied by pain or significant discomfort beyond a mild scratchy feeling, or if there are any changes in vision, such as blurriness or double vision, a doctor should be consulted. The presence of any discharge from the eye, a history of recent eye trauma, or recurrent hemorrhages without a clear cause also necessitate a medical evaluation. Additionally, if the red patch does not begin to fade within two weeks, or if other symptoms like headache, nausea, or vomiting are present, it is important to seek professional medical advice. These signs could indicate a more serious underlying condition that requires diagnosis and treatment.
