Blood in the White Part of the Eye

Blood in the White Part of the Eye

If you see blood in the white part of the eye, known medically as a subconjunctival hemorrhage, it may look alarming but in fact it almost always is harmless. It simply is a small blood vessel in the eye that popped. It could be caused by a variety of reasons, some as mild as coughing or sneezing, and it usually passes on its own within two weeks or so.

Schedule an appointment with your eye doctor if the red spot doesn’t go away within 2-3 weeks, if you are in pain or are experiencing changes in your vision, if there’s more than one red spot or if the blood is located in the colorful part of your eye, known as the iris.

Symptoms and Causes

A red spot in the white part of the eye is usually not accompanied by any other symptoms, other than a possible scratchy feeling on the surface of your eye. 

The blood vessel that popped is right under the conjunctiva which is a clear membrane that covers the surface of the eye and contains lots of small blood vessels. The blood is not in an area of the eye that affects your vision and that’s why this condition should not cause any changes in your vision. The red spot on your eye may get bigger within a day or two but then it usually starts turning a more yellowish hue as the eye begins to absorb the blood.

The most common causes of a subconjunctival hemorrhage are:

  • Very strong sneezing or coughing
  • Strain 
  • Vomiting 

Sometimes it could result from other factors such as:

  • Rubbing your eye in a rough manner
  • Something stuck in your eye
  • Contact lenses
  • Virus
  • Surgery 

Less common causes are:

  • High blood pressure
  • Diabetes
  • Certain blood thinning medications
  • Blood clotting conditions

The chances of getting a subconjunctival hemorrhage increase after age 50 since it’s more common in this age group to develop diabetes or high blood pressure, however these illnesses are considered to be uncommon causes for a red spot in the eye.

If you notice these symptoms or experience changes in your vision and find it difficult for you to perform your daily activities, please schedule an eye exam with our eye doctor in New York.


A red spot in your eye is not always something that can be prevented, however there are certain recommendations of precautions that can be takes such as:

  • Be careful to rub your eyes very gently
  • Take good care of your contact lenses to make sure that they are properly cleaned
  • Wear proper protective gear to prevent eye injury
  • If you have a bleeding disorder, try to keep it under control and you can discuss with your healthcare provider what to do to try to prevent a subconjunctival hemorrhage


There is no treatment or method to speed up the natural healing of most subconjunctival hemorrhages. Your eye doctor may recommend using artificial tears to help with discomfort. If the bleeding appeared due to an underlying cause or condition, then the proper treatment will be provided to deal with the cause.

Common Questions

You can take a deep breath of relief because a red spot in the eye looks so much scarier than it really is. It almost always is harmless as it’s just a popped blood vessel right under the surface of the eye. You can schedule an appointment with your eye doctor who can check to make sure that there are no underlying conditions which very rarely could be the cause for a red spot in the eye. Most often the appearance of blood at the front of the eye will go away on its own in approximately two weeks or so.
A red spot in the eye can appear without any apparent cause for it. It could be a result of coughing or sneezing too hard so there isn’t really a way to usually prevent the appearance of a red spot in the eye, but there are certain precautions that could be taken in order to prevent more uncommon causes for it. These tips include being careful not to rub your eyes too hard, wear protective gear if your eyes are at risk for an injury and keep your contact lenses clean. Also, if you have a bleeding disorder, consult with your doctor how to keep it under control.
There are many reasons why you may have a red spot or blood spot in your eye. Subconjunctival hemorrhages vary from a small dot to looking like your whole eye is bleeding under the lens. This is caused by a burst blood vessel and is very similar to a bruise. However, the reason why so many people are scared by a bruise in your eye is that it is significantly more visible because it is under the clear and transparent conjunctiva in front part of your sclera. Potential causes include: An eye injury that causes your blood vessels to burst Rubbing your eyes causing a rupture of a blood vessel which leads to a blood spot in your eye Straining from constipation or lifting something heavy can cause burst capillaries A strong sneeze or cough Blood disorders such as sickle cell anemia Frequent usage of blood thinners such as aspirin and interferon While a blood spot in the eye usually means that there is internal bleeding in your eye, also known as subconjunctival hemorrhage, it is generally not something that you should worry about. Though the eye may look frightening, there should be no change in vision, discharge, or pain. Please contact our clinic at (212) 752-6930 if the blood does not go away after 2 or 3 weeks, if you are experiencing pain or vision problems, or if you have more than one subconjunctival hemorrhage.

At Amplify with Dr Wernick I was seeking help for seemingly intractable, probably age-related dryness. I've seen other doctors about it, and that has been helpful, but what he explained to me about it and the careful way he answered all my questions gave me so much more of a clear understanding of what is going on (and is not) that I am more able to implement all his and others' recommendations than I was before. And he gave me additional resources for further follow-up. I am most grateful.

Wow! This is a great Eye Care medical facility. I was thoroughly examined by Dr. Pinkhasov for over 2 hours. She made sure to check my eyes for pretty much everything and patiently explained proper care for my eyes. They definitely know how to provide great care and treat their patients right. Now I know why they have such a great reputation and been around for so long.

Dr. Kavner is a gifted diagnostician and orthoptic therapist. He treated me several decades ago for a condition similar to dyslexia. I was having migraines five times per week. I worked with him for about a year and I experienced tremendous improvement (down to 3-4 per year) that has lasted.

Dr. Kavner recommended two types of eye therapy for my daughter. One of them using bio-feedback. In just three sessions she is seeing considerably better. She shouted this morning: Ooh my God! I could not see these letters with my glasses on, and now I can see them without my glasses. If you are willing and able to invest in improving your vision, this is a good place to go to!

I have always found Dr Kavner's work, expertise and wisdom of the highest caliber. As one of the fathers of OT, occupational othomology, his depth and breadth of knowledge about the eyes' health and wellbeing of the patient is exemplary. Cannot say enough good things about him.
