Bloodshot eyes while wearing contact lenses?
Hello doctor, I haven't worn contact lenses for about six months.
Yesterday, I wore them for over 12 hours, and when I got home, I noticed that the outer part of the sclera in my left eye was filled with radiating red blood vessels.
This morning, there hasn't been any improvement.
Should I see a doctor? Is this related to my previous retinal tear (which has been treated with laser)? I'm currently abroad and it's inconvenient to see a doctor, so I'm seeking your advice.
Thank you.

The recommended wearing time for contact lenses is within 8 hours.
Exceeding this duration can lead to increased hypoxia in the cornea as the wearing time increases.
Consequently, after removing the contact lenses, there may be surface congestion due to hypoxic irritation, which is generally not a cause for concern.
However, if the condition persists or if there is pain, it is essential to consult an ophthalmologist.

More Info
When you notice red veins in your eye after wearing contact lenses, especially after an extended period of use, it can be concerning. The appearance of these red veins, known as conjunctival injection or hyperemia, often indicates that the eye is experiencing some form of irritation or stress. In your case, wearing contact lenses for over 12 hours after a long break may have led to oxygen deprivation in the cornea, which is a common issue when lenses are worn for too long.
Contact lenses can restrict the amount of oxygen that reaches the cornea, especially if they are not designed for extended wear. The cornea relies on oxygen from the air, and when it is deprived, it can become inflamed, leading to redness and discomfort. This is likely what you are experiencing with the red veins in your eye. If the redness persists, or if you experience pain, discomfort, or changes in vision, it is essential to seek medical attention from an eye care professional.
Regarding your previous retinal tear and the laser treatment you received, it is understandable to be concerned about whether this issue is related. While the red veins in your eye are not directly indicative of a retinal problem, any significant changes in your eye health should be monitored closely, especially given your history. Retinal issues typically present with symptoms such as flashes of light, floaters, or a shadow in your vision, rather than redness in the eye. However, it is always best to err on the side of caution and consult with an eye care professional if you have any doubts.
In the meantime, here are some recommendations to help alleviate the redness and discomfort:
1. Remove the Contact Lenses: If you haven't already, take out your contact lenses immediately to allow your eyes to breathe and recover.
2. Use Artificial Tears: Over-the-counter artificial tears can help lubricate your eyes and reduce irritation. Look for preservative-free options if you plan to use them frequently.
3. Cold Compress: Applying a cold compress over your closed eyes can help reduce inflammation and soothe discomfort.
4. Avoid Rubbing Your Eyes: Rubbing can exacerbate irritation and lead to further complications.
5. Rest Your Eyes: Give your eyes a break from screens and bright lights to help them recover.
6. Monitor Symptoms: Keep an eye on your symptoms. If the redness does not improve within a day or two, or if you develop additional symptoms like pain or vision changes, seek medical attention as soon as possible.
7. Consult a Professional: If you are in a location where seeing a doctor is challenging, consider reaching out to a telemedicine service that specializes in eye care. They may be able to provide guidance based on your symptoms and history.
In conclusion, while the red veins in your eye after wearing contact lenses may not be immediately alarming, they warrant attention, especially given your medical history. Taking proactive steps to care for your eyes and seeking professional advice when necessary is crucial for maintaining your eye health.
