Allergic Conjunctivitis and Eye Fatigue: Symptoms and Solutions

Allergic conjunctivitis and eye fatigue?

Hello, doctor! I was first diagnosed with allergic conjunctivitis last December.
The symptoms included redness and itching.
After the doctor prescribed medication, my eyes felt fine after a few days, so I stopped using the drops.
In April of this year, I experienced the same symptoms and was again diagnosed with allergic conjunctivitis.
However, this time, after two weeks, my eyes are still itchy.
I have been working in a drawing and creative field for two years, which involves long hours in front of a screen.
I'm concerned that I might be experiencing eye fatigue or possibly some dry eye syndrome.
I have never worn contact lenses and have had over 700 degrees of myopia, which I haven't had checked in several years.
My symptoms mainly consist of redness and itching, and I wake up with dry eyes but no discharge.
My vision seems normal.
Currently, I have the following issues:
1.
In the morning, my eyes are particularly red and dry.
Using eye drops helps significantly, but by the afternoon, I don't feel much discomfort.
However, sometimes after resting my eyes for an hour, the symptoms return.
This has been ongoing for several years, and I don't know the cause.

2.
Could eye fatigue be causing the persistent redness? Since I was first diagnosed with allergies, it seems like the redness has not subsided.
The most uncomfortable area is the inner part of my eyes, but the redness on the outer side also hasn't gone away, although it doesn't feel uncomfortable.

3.
I previously read that persistent redness could be due to vascular proliferation, but the doctor mentioned that I shouldn't worry since I don't wear contact lenses.
I'm just concerned that excessive eye strain might lead to this possibility.

More Info

Allergic conjunctivitis is a common condition characterized by inflammation of the conjunctiva, the thin membrane that covers the white part of the eye and the inner surface of the eyelids. It is often triggered by allergens such as pollen, dust mites, pet dander, or mold. Symptoms typically include redness, itching, tearing, and swelling of the eyes. In your case, it appears that you have experienced recurrent episodes of allergic conjunctivitis, which can be exacerbated by prolonged screen time and eye fatigue.

1. Morning Redness and Dryness: It is not uncommon for individuals with allergic conjunctivitis to experience increased redness and dryness upon waking. This can be due to several factors, including the natural decrease in tear production during sleep and exposure to allergens in your sleeping environment. Additionally, if you are sleeping in a room with air conditioning or heating, the dry air can further exacerbate dryness. Using artificial tears upon waking can help alleviate these symptoms. It’s also beneficial to ensure that your sleeping environment is free from allergens, such as dust mites, by regularly washing bedding and using hypoallergenic covers.

2. Persistent Bloodshot Eyes: The presence of blood vessels in the conjunctiva can be a sign of chronic irritation or inflammation. If you have been diagnosed with allergic conjunctivitis, the bloodshot appearance may persist due to ongoing exposure to allergens or irritants, especially if you are frequently using screens. Eye fatigue can indeed contribute to the appearance of redness, as prolonged screen time can lead to digital eye strain, characterized by symptoms such as dryness, irritation, and blurred vision. It is essential to take regular breaks using the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds. This practice can help reduce eye strain and may improve the overall appearance of your eyes.

3. Vascular Changes: The concern regarding blood vessel proliferation (neovascularization) is valid, especially in cases of chronic irritation. However, since you are not wearing contact lenses, the risk of significant neovascularization is lower. Chronic irritation from allergens or excessive screen time can lead to vascular changes, but these are typically reversible with appropriate management. If your symptoms persist or worsen, it may be worthwhile to consult with an eye care professional for a comprehensive evaluation. They may recommend treatments such as antihistamine eye drops or corticosteroids to reduce inflammation and redness.

4. Dry Eye Symptoms: Given your long hours of screen time and the symptoms you describe, it is possible that you are also experiencing dry eye syndrome. This condition occurs when the eyes do not produce enough tears or when the tears evaporate too quickly. Symptoms include dryness, irritation, and a gritty sensation. If you suspect dry eyes, consider incorporating regular use of preservative-free artificial tears into your routine, especially during and after prolonged screen use.

5. Regular Eye Exams: Since you mentioned that you have not had your vision checked in several years, it would be prudent to schedule a comprehensive eye exam. This will help assess your current vision status, check for any underlying conditions, and ensure that your prescription is up to date. Regular eye exams are essential, especially for individuals with high myopia (like your prescription of -7.00), as they can help detect any changes in eye health early on.

In summary, managing allergic conjunctivitis and eye fatigue involves a combination of avoiding allergens, using artificial tears, taking regular breaks from screens, and maintaining a healthy eye care routine. If symptoms persist, do not hesitate to seek further evaluation from an eye care professional. They can provide tailored advice and treatment options to help alleviate your symptoms and improve your overall eye health.
