Issues with the sclera?

Hello Doctor, sometimes my eyes feel very itchy, and when I look in the mirror, I notice that the whites of my eyes are red.
Occasionally, in addition to the redness, they also have a litchi-like appearance, but most of the time it subsides within an hour.
This occurs more frequently in the summer.
I read online that this condition is similar to allergies.
If it doesn't persist, I can monitor it myself.
I would like to ask if there are any preventive measures I can take.
Thank you.

More Info

Red and itchy eyes can be a common issue that many people experience, often linked to a variety of causes, including allergies, environmental factors, and underlying health conditions. Understanding the reasons behind these symptoms is crucial for effective management and prevention.

Causes of Red and Itchy Eyes
1. Allergic Reactions: One of the most common causes of red and itchy eyes is allergies. Seasonal allergies, often triggered by pollen, dust mites, or pet dander, can lead to symptoms such as redness, itching, and swelling. This condition is known as allergic conjunctivitis. When allergens come into contact with the eyes, they can cause the release of histamines, leading to inflammation and irritation.

2. Dry Eyes: Insufficient tear production can lead to dry eyes, which may cause redness and discomfort. This condition can be exacerbated by prolonged screen time, dry environments, or certain medications. When the eyes are dry, they may become irritated and red, prompting a reflexive itch.

3. Infections: Conjunctivitis, or pink eye, can also cause red and itchy eyes. This can be viral, bacterial, or allergic in nature. Infections often come with additional symptoms such as discharge, crusting, and increased tearing.

4. Environmental Factors: Exposure to smoke, pollution, or strong winds can irritate the eyes, leading to redness and discomfort. Additionally, swimming in chlorinated pools can also cause irritation.

5. Contact Lens Use: For those who wear contact lenses, improper use or wearing them for extended periods can lead to irritation and redness. It’s essential to follow proper hygiene and care instructions for contact lenses.

Prevention Tips
1. Avoid Allergens: If you suspect that your symptoms are related to allergies, try to identify and avoid triggers. Keeping windows closed during high pollen seasons, using air purifiers, and regularly cleaning your living space can help reduce exposure to allergens.

2. Use Artificial Tears: For dry eyes, over-the-counter artificial tears can provide relief by lubricating the eyes and reducing irritation. It’s important to choose preservative-free options if you plan to use them frequently.

3. Practice Good Hygiene: Wash your hands regularly and avoid touching your eyes to prevent infections. If you wear contact lenses, ensure they are cleaned properly and replaced as recommended.

4. Limit Screen Time: To reduce eye strain and dryness, take regular breaks when using screens. The 20-20-20 rule is effective: every 20 minutes, look at something 20 feet away for at least 20 seconds.

5. Consult a Healthcare Professional: If your symptoms persist or worsen, it’s important to consult an eye care professional. They can provide a proper diagnosis and recommend appropriate treatments, which may include prescription medications or allergy testing.

Conclusion
In summary, red and itchy eyes can be caused by a variety of factors, including allergies, dry eyes, infections, and environmental irritants. Understanding the underlying cause is essential for effective management. By taking preventive measures and seeking professional advice when necessary, you can alleviate symptoms and maintain eye health. If your symptoms are recurrent or severe, it’s advisable to consult with an eye care specialist for a comprehensive evaluation and tailored treatment plan.
