Red Veins in the Eyes: Causes and Contact Lens Concerns - Ophthalmology

Hello! Thank you for your question regarding the appearance of red veins in your eyes and concerns related to contact lens wear.
The presence of red veins in the eyes, particularly when wearing contact lenses, can be attributed to several factors. One common cause is the irritation or inflammation of the conjunctiva, which can occur due to prolonged contact lens wear. This irritation can lead to a condition known as "neovascularization," where new blood vessels form in response to low oxygen levels in the cornea. This is often a result of wearing contact lenses that do not allow sufficient oxygen to reach the cornea, especially if they are worn for extended periods or if they are not properly cleaned and maintained.

When you notice red veins or bloodshot eyes, it may not always indicate a serious issue, but it is essential to pay attention to accompanying symptoms. Common symptoms associated with neovascularization or other forms of irritation include:
1. Redness: This is the most visible sign and can range from mild to severe.

2. Discomfort or Pain: You may experience a sensation of grittiness, burning, or general discomfort.

3. Dryness: Many individuals report a feeling of dryness, which can be exacerbated by contact lens wear.

4. Sensitivity to Light: Increased sensitivity to bright lights can occur.

5. Tearing: Your eyes may produce more tears in response to irritation.

6. Vision Changes: In some cases, vision may become blurry if the irritation is significant.

If you are experiencing these symptoms, it is crucial to take a break from wearing your contact lenses and consult with an eye care professional. They can perform a thorough examination to determine the extent of any neovascularization and assess the health of your cornea and conjunctiva.
Regarding your question about whether you can continue wearing contact lenses if neovascularization is present, the answer depends on the severity of the condition. In mild cases, your eye care provider may recommend switching to a different type of contact lens, such as those made from silicone hydrogel, which allows for better oxygen permeability. They may also suggest reducing the wearing time of your lenses and ensuring that you follow proper hygiene practices.

If the neovascularization is more severe, your eye care provider may advise against wearing contact lenses until the condition improves. This is to prevent further irritation and potential complications, such as corneal scarring or infections.

In addition to consulting with your eye care provider, here are some general tips for maintaining eye health while wearing contact lenses:
1. Follow the Recommended Wear Schedule: Adhere to the prescribed wearing schedule for your lenses, whether they are daily, bi-weekly, or monthly disposables.

2. Practice Good Hygiene: Always wash your hands before handling your lenses, and ensure that your lens case and solution are clean and replaced regularly.

3. Use Rewetting Drops: If you experience dryness, consider using rewetting drops specifically designed for contact lens wearers.

4. Take Breaks: Give your eyes a break from contact lenses by wearing glasses periodically, especially if you notice any discomfort.

5. Stay Hydrated: Drink plenty of water to help maintain overall eye moisture.

In conclusion, while the appearance of red veins in your eyes can be concerning, it is essential to assess the situation with the help of a qualified eye care professional. They can provide personalized recommendations based on your specific condition and help you maintain healthy vision while using contact lenses. Thank you for your question, and I hope this information helps you!
