A red dot on the eye can be a concerning and sometimes alarming symptom, especially if you're not sure what it is or what it means. Also known as a subconjunctival hemorrhage, a red dot or spot on the eye is typically a small, harmless condition that can appear as a result of various factors. In this article, we will explore the possible causes, concerns, and what you can do if you notice a red dot on your eye.
The white part of your eye is covered by a thin membrane called the conjunctiva, which helps keep your eye moist and protected. When a small blood vessel in this membrane breaks, it can cause bleeding underneath the conjunctiva, leading to the appearance of a red spot or dot on the eye. This condition is usually painless and may not affect your vision.
Causes of a Red Dot on the Eye
There are several reasons why you might notice a red dot on your eye. Some of the most common causes include:
- Increased blood pressure: High blood pressure can cause small blood vessels in the eye to break, leading to a subconjunctival hemorrhage.
- Eye strain: Prolonged use of digital devices, reading, or other activities that require focused attention can cause eye strain, which may lead to a red dot on the eye.
- Allergies: Seasonal allergies, dust, or other irritants can cause inflammation and lead to a red spot on the eye.
- Injury: A minor injury to the eye, such as rubbing it too hard or getting hit with a small object, can cause a blood vessel to break.
- Infections: Certain infections, such as conjunctivitis, can cause redness and inflammation in the eye.
Symptoms and Concerns
In most cases, a red dot on the eye is not a cause for concern and will resolve on its own within a week or two. However, if you experience any of the following symptoms, you should seek medical attention:
- Pain or discomfort in the eye
- Changes in vision
- Increased sensitivity to light
