There are blood vessels in the eyes?


Hello, doctor! I have worn contact lenses about five times in the past three weeks.
However, in the last week or two, I have been hesitant to wear them again.
I have noticed a red line of blood vessels on the sclera of my left eye, extending from the corner of the eye close to the cornea.
It appears that the blood vessels are originating from the corner of the eye.
When I look to the right, the red line seems to stretch along with my eye movement.
It has not resolved and has been present for three weeks.
What should I do to address this? I have not worn contact lenses before.

Hello: Contact lenses can cause corneal hypoxia and recurrent corneal neovascularization; however, these blood vessels are very small and not easily visible to the naked eye, and they typically develop with prolonged wear.
The blood vessels on the white blood cells are likely due to the dilation of conjunctival vessels, which usually occurs as a response to inflammatory stimuli.
The specifications, materials, wearing methods, and cleaning procedures of contact lenses are all potential contributing factors.
It is recommended that you visit an ophthalmologist for a detailed examination to identify the cause.
Thank you, Dr.

Hello! Thank you for reaching out with your concerns regarding the red veins in your eye. Based on your description, it seems that you are experiencing a condition known as conjunctival injection or conjunctival hyperemia, which is characterized by the dilation of blood vessels in the conjunctiva, leading to the appearance of red veins in the white part of the eye (sclera). This can be particularly alarming, especially if it persists for several weeks.

There are several potential causes for the appearance of red veins in the eye, especially after wearing contact lenses. Here are some common reasons:
1. Irritation from Contact Lenses: If you are new to wearing contact lenses, your eyes may not be accustomed to them. This can lead to irritation, which causes the blood vessels to dilate and become more prominent. It's crucial to ensure that your lenses are clean and that you are following the recommended wearing schedule.

2. Dry Eyes: Contact lens wearers often experience dryness, which can exacerbate redness. If your eyes are not producing enough tears, this can lead to irritation and redness. Using lubricating eye drops specifically designed for contact lens wearers can help alleviate this issue.

3. Allergic Reactions: Allergies to dust, pollen, or even the materials in the contact lenses can cause redness and irritation. If you suspect allergies, consider using antihistamine eye drops after consulting with a healthcare provider.

4. Infections or Inflammation: Conditions such as conjunctivitis (pink eye) or keratitis (inflammation of the cornea) can cause redness and discomfort. If you experience any discharge, increased sensitivity to light, or significant discomfort, it is essential to seek medical attention promptly.

5. Subconjunctival Hemorrhage: This occurs when a small blood vessel breaks just beneath the conjunctiva, leading to a bright red patch on the white of the eye. While it can look alarming, it is usually harmless and resolves on its own within a couple of weeks.

To address your situation, here are some steps you can take:
- Avoid Contact Lenses: Since you have been hesitant to wear them, it may be wise to give your eyes a break from contact lenses until the redness resolves. Consider wearing glasses instead.

- Consult an Eye Care Professional: Since the redness has persisted for three weeks, it is advisable to see an eye doctor. They can perform a thorough examination to determine the underlying cause and recommend appropriate treatment.

- Use Artificial Tears: If dryness is a concern, using preservative-free artificial tears can help keep your eyes lubricated and reduce irritation.

- Practice Good Hygiene: Ensure that your hands are clean before handling your contact lenses, and follow the recommended cleaning and storage procedures.

- Monitor Symptoms: Keep track of any additional symptoms such as pain, vision changes, or discharge. If these occur, seek medical attention immediately.

In conclusion, while red veins in the eye can be concerning, they are often manageable with proper care and attention. It is essential to listen to your body and seek professional advice when needed. Taking these steps can help ensure the health of your eyes and provide you with peace of mind. If you have any further questions or concerns, don’t hesitate to reach out for more information.
