Are you noticing a red dot in your eye and wondering what it could be? It’s a common concern, and as WHY.EDU.VN explains, it’s often a harmless condition called a subconjunctival hemorrhage. This occurs when a small blood vessel breaks under the conjunctiva. While usually not serious, a red spot may occasionally indicate a more significant underlying issue. Keep reading to explore the potential causes, necessary treatments, and when you should seek expert medical assistance. Understanding the possible reasons, such as eye trauma, high blood pressure, or even rare eye diseases, will put your mind at ease and allow you to respond appropriately.
1. Understanding The Common Cause: Subconjunctival Hemorrhage
A red spot on the eye is frequently the result of a small blood vessel that has burst open, a condition known as a subconjunctival hemorrhage. This is a common occurrence and often not a cause for serious concern.
Beneath the conjunctiva, the clear coating covering the sclera (the white part of your eye), there are tiny blood vessels. When one of these vessels breaks, the blood becomes visible under the conjunctiva. If a larger vessel ruptures, it can appear quite alarming, with the blood potentially spreading across the entire white of the eye.
Seeing a large red spot in your eye can be unsettling. However, most of the time, it is painless and doesn’t cause irritation or light sensitivity. The reasons for these blood vessels bursting can vary and are often related to physical stress rather than emotional stress.
Common causes of subconjunctival hemorrhage include:
- Trauma to the eye
- Straining due to constipation
- Straining from sneezing, coughing, or vomiting
- Lifting heavy objects
Anyone can experience a subconjunctival hemorrhage, but certain conditions such as diabetes, which affects blood sugar levels, and hypertension (high blood pressure) can increase the risk.
Generally, this condition does not require treatment. The red spot typically disappears on its own within a week, though larger hemorrhages may take a bit longer to resolve. As it heals, it may resemble a yellowish bruise.
If the spot is large or causes discomfort, a healthcare provider might recommend artificial tears or cold compresses to alleviate swelling.
Even if you suspect your red spot is a simple subconjunctival hemorrhage, consulting a healthcare provider is always prudent, especially if the issue recurs. It’s similar to a bruise on your skin, but in the eye, the blood-red color is more noticeable because it’s under the transparent conjunctiva.

2. Exploring Other Potential Causes Of Red Spots On The Eyes
If you observe a red spot on your eye, several other conditions might be responsible. Your eye care professional may consider these possibilities during an examination.
2.1. Episcleritis
Episcleritis is an inflammatory condition affecting the episclera, the thin layer of tissue between the conjunctiva and the sclera. This condition is characterized by its sudden onset.
While episcleritis can appear alarming, most cases are benign and resolve independently. However, approximately one-third of episcleritis cases are associated with underlying inflammatory conditions affecting other parts of the body.
2.2. Pinguecula
A pinguecula is a common, benign growth or thickening of the conjunctiva. It often appears raised and yellowish in color. Pingueculae are believed to result from exposure to ultraviolet (UV) rays from the sun or chronic irritation.
Individuals may be unaware of a pinguecula until it becomes inflamed, which can occur after prolonged exposure to sun and wind. When inflamed, the condition is known as pingueculitis, characterized by redness and swelling.
Treatment for a pinguecula is usually unnecessary unless it causes discomfort. Surgical removal is an option for symptomatic or cosmetic reasons.
2.3. COVID-19 and Eye Symptoms
Yes, it is possible for a COVID-19 infection to lead to serious eye conditions, including bleeding from blood vessels in the eye. Those with underlying conditions like diabetes or high blood pressure are at greater risk. Conjunctivitis (pink eye) remains a common COVID symptom, especially in children.
2.4. Conjunctival Hemangioma
A conjunctival hemangioma is a cluster of tangled blood vessels on the white part of the eye. This condition is almost always congenital, meaning it is present from birth, typically appearing shortly after. In most cases, these hemangiomas disappear as the child grows.
Rarely, conjunctival hemangiomas can develop in adults over the age of 60. Although usually harmless, it’s recommended to have them checked annually by an eye care professional.
2.5. Sickle Cell Disease
Sickle cell disease is an inherited blood disorder characterized by chronic anemia (reduced healthy red blood cells) and recurrent pain episodes. The disease results from abnormally shaped hemoglobin molecules, which are responsible for carrying oxygen in red blood cells. These abnormal hemoglobin molecules can cause red blood cells to rupture, resulting in a sickle shape.
Patients with sickle cell disease may exhibit comma-shaped red spots or lines on the white part of their eyes. These occur due to the sickle-shaped blood cells causing blockages in small blood vessels.
2.6. Red Spots After LASIK Surgery
Red spots appearing after LASIK surgery are often caused by subconjunctival hemorrhage. Other eye procedures, such as laser treatment for cataracts, can also result in red spots on the eye for the same reason.
2.7. Benign and Cancerous Growths
Certain growths on the eye can be serious and require medical attention. These include:
- Keratoacanthoma: A type of skin cancer that can form on the eye.
- Actinic Granuloma: A rare skin disorder.
- Conjunctival Epitheliomas: Abnormal growths in the tissue covering the eye.
If you observe any new growths on the surface of your eye, it is essential to consult your eye doctor as soon as possible.
3. When Is It Necessary To Consult A Healthcare Provider?
It is important not to ignore a red spot in your eye. If the spot persists for more than a few days, it is advisable to seek consultation with an eye care professional. A comprehensive eye examination can help your healthcare provider rule out any serious underlying conditions.
