Eye Fatigue: Causes, Symptoms, and Treatment Options

Q: Eye Fatigue: Causes, Symptoms, and Treatment Options

Hello： Based on your description, the symptoms you mentioned mainly include floaters, intermittent strabismus, blurred vision, and eye fatigue. <br>Here are the responses to these issues：<br>Floaters： Floaters refer to the appearance of floating black dots or lines in your vision

Eye fatigue

In early May, I had a follow-up appointment for a floaters examination because I felt like there were things flashing when looking at a white wall, and when I closed my eyes, I felt like there were things constantly moving, similar to blobs of light.
I would like to ask if floaters can also be seen when my eyes are closed.
During the examination, the doctor said there was no issue, but I have had intermittent strabismus since last year and have been prescribed glasses for reading.
Recently, when wearing my regular glasses, I noticed that when I relax and look at nearby objects, I still experience double vision, but both images appear blurry.
In the past, both images were clear even with double vision, but I could still see clearly when I focused hard.
Is this a sign that my intermittent condition is worsening or that my prescription has changed? I have high myopia, and although wearing glasses for near vision feels better, I can't wear them for too long without feeling strain and fatigue.
I do a fixed finger focus exercise once a day, but I feel like there has been no improvement since last year, and I often feel anxious and sad.
My eyes frequently feel fatigued, and sometimes I experience sharp pain once or twice.
The doctor prescribed me Scopolamine eye drops, but I run out quickly because I use them daily.
I have also been purchasing Similasan Eye Drops from the pharmacy, which claims to relieve fatigue and add vitamins.
I use them at least two to three times a day, usually in the morning, afternoon, and before bed.
I would like to ask if this can be used long-term and if there are any concerns regarding steroids or preservatives.
Although I have already gone through two bottles, I noticed that the area under my lower eyelid looks slightly yellow when I look in the mirror.
Is this due to prolonged use of the eye drops, or is there another issue?

Hello: Based on your description, the symptoms you mentioned mainly include floaters, intermittent strabismus, blurred vision, and eye fatigue.
Here are the responses to these issues:
Floaters: Floaters refer to the appearance of floating black dots or lines in your vision, which are usually caused by fibers or particles in the vitreous humor.
Typically, floaters are not seen when your eyes are closed because they are images created by external light entering the eye.
However, you mentioned that you still feel something flashing when your eyes are closed, which may be due to certain stimuli on the retina or the pulling effect of the vitreous.
If the symptoms of floaters worsen significantly or are accompanied by flashes of light, it is advisable to return to an ophthalmologist for an examination to rule out retinal tears or other issues.
Intermittent Strabismus: Intermittent strabismus can cause the eyes to fail to work together properly, resulting in double vision or blurred vision.
Your description indicates that even when relaxed, you experience double vision when looking at nearby objects, and both images become blurred, which may suggest a change in your strabismus condition.
Individuals with high myopia may experience fluctuations in vision, especially during visual fatigue or difficulty focusing.
If your glasses prescription is insufficient to correct this condition, a re-evaluation of your prescription may be necessary.
Additionally, you mentioned that focusing hard allows you to see clearly, indicating that your eyes still have some accommodative ability, but this may lead to eye fatigue.
Eye Fatigue and Eye Drops: You are currently using two types of eye drops to alleviate eye fatigue.
Sancobac eye drops are primarily used to relieve eye fatigue.
Similasan Eye Drops claim to contain vitamins suitable for reducing eye fatigue; however, eye drops typically contain preservatives to prevent spoilage.
Neither of these eye drops contains steroids.
Long-term use should not exceed four times a day.
Regarding the pale yellow phenomenon under your eyelids, it is recommended to visit an ophthalmologist for further evaluation.
Recommendations:
1.
Floaters: If the symptoms are significant or change, it is advisable to see an ophthalmologist to rule out retinal-related issues.
2.
Intermittent Strabismus: A re-evaluation of vision and glasses prescription is needed, and consider visual training or other corrective measures.
3.
Eye Fatigue and Eye Drops: It is recommended to consult an ophthalmologist before long-term use of eye drops to ensure the selection of appropriate products and to have regular eye health check-ups.

More Info

Eye fatigue, also known as asthenopia, is a common condition that can arise from various factors, particularly in our modern world where screen time is prevalent. The symptoms you've described, including difficulty focusing, feelings of strain, and even intermittent double vision, are indicative of underlying issues that may need to be addressed.

Causes of Eye Fatigue
1. Refractive Errors: Conditions such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism can lead to eye strain, especially if they are uncorrected. Given your history of high myopia, it’s crucial to ensure that your prescription is up to date.

2. Overuse of Digital Devices: Prolonged screen time can lead to digital eye strain. Symptoms include dryness, irritation, and difficulty focusing. The 20-20-20 rule is often recommended: every 20 minutes, look at something 20 feet away for at least 20 seconds to help alleviate strain.

3. Muscle Fatigue: The eye muscles, particularly the ciliary muscle responsible for focusing, can become fatigued from constant near work. This can lead to symptoms like blurred vision and discomfort.

4. Dry Eye Syndrome: Insufficient tear production can cause discomfort and fatigue. Symptoms may include a gritty sensation, redness, and blurred vision.

5. Intermittent Strabismus: Your mention of intermittent strabismus (crossed eyes) can also contribute to visual discomfort and double vision, particularly when focusing on near objects.

Symptoms to Monitor
- Visual Disturbances: The presence of floaters or flashes of light, especially if they change or increase, should be evaluated by an eye care professional.

- Pain or Discomfort: Persistent pain, especially if accompanied by changes in vision, warrants further investigation.

- Color Changes: The yellowing of the conjunctiva or eyelids may indicate irritation or a reaction to prolonged use of certain eye drops.

Treatment Options
1. Regular Eye Exams: Ensure you have regular check-ups with an eye care professional to monitor your vision and update your prescription as needed.

2. Corrective Lenses: If you have not already, consider getting a pair of glasses specifically for reading or computer work. Progressive lenses or bifocals may help if you are experiencing early presbyopia.

3. Eye Drops: While over-the-counter lubricating eye drops can help alleviate dryness, be cautious with prolonged use of any medicated drops. Always consult with your eye doctor regarding the safety and appropriateness of long-term use.

4. Lifestyle Adjustments: Implementing ergonomic practices at your workstation, taking regular breaks, and ensuring proper lighting can significantly reduce eye strain.

5. Eye Exercises: Engaging in eye exercises, such as focusing on a near object and then a distant one, can help strengthen eye muscles and improve flexibility.

6. Stress Management: Anxiety and stress can exacerbate symptoms of eye fatigue. Techniques such as mindfulness, yoga, or even simple breathing exercises can help manage stress levels.

Regarding Your Eye Drops
You mentioned using "獅美露保視捷" eye drops frequently. While many lubricating drops are safe for long-term use, it’s essential to check for preservatives, as some can cause irritation with prolonged use. If you notice any changes in your eye appearance or persistent discomfort, consult your eye doctor. They can recommend alternatives or assess whether your symptoms are related to the drops.

Conclusion
Eye fatigue can be multifactorial, and addressing it often requires a comprehensive approach that includes proper eye care, lifestyle modifications, and possibly corrective lenses. If your symptoms persist or worsen, it’s crucial to follow up with your eye care provider for further evaluation and tailored treatment options.
