Eye Fatigue: Causes, Symptoms, and Solutions

Eye fatigue

Hello, Doctor Gao.
Thank you for taking the time to answer my questions! I sincerely appreciate it.
Around early August, I suddenly experienced light sensitivity in my right eye when looking at the computer.
I consulted a doctor who prescribed eye drops for fatigue.
During this time, I have tried to minimize my screen time to allow my eyes to recover.
However, I have noticed that after watching TV for a short period (about 30 to 60 minutes), my right eye becomes uncomfortable, while my left eye does not.
Additionally, due to the light sensitivity, I soon noticed four darker floaters in my right eye—one is black, and the others are light brown, which are usually not noticeable unless I pay close attention.
Since early August, unless I deliberately look at the sky or squint at fluorescent lights, I only see the usual floaters moving.
Now, I don't need to focus as much; both eyes seem to have a swarm of floaters, and whenever I move my eyes, many appear.
Even during nighttime activities or cycling, I see darker floaters moving, even in dim light.
By September, I noticed an additional floater, and now I see them everywhere at night.
I even see darker floaters moving in my factory, while other translucent or transparent ones are invisible.
In places like indoors, supermarkets, and hospitals, I can only see floaters when I look at fluorescent lights; otherwise, they are not visible.
I have seen doctors three times, and they performed dilated fundus examinations, confirming that my retina is normal.
I would like to ask the doctor: 1.
Can my light-sensitive right eye recover? Will it stop feeling uncomfortable after a short time of watching TV? 2.
Why do I increasingly see floaters at night? Is there an issue with my retina? 3.
Is it normal for floaters to have color? 4.
Is it possible that both eyes are showing all types of floaters due to excessive fatigue? My vision is approximately 600-650, with astigmatism of 75 and 150.
I have asked doctors, and they all say my retina is fine, but if the retina is normal, why am I experiencing this? I have woken up several times at night because I am unsure of the exact source of the problem! Now, even at night, they appear.
I hope Doctor Gao can answer my questions! Thank you again, Doctor.

Hello,
1.
There are many reasons for photophobia; it could be due to fatigue or an inflammatory condition.

2.
If you see floaters and your retinal examination is normal, there is no need to worry.

3.
The size, shape, quantity, and color intensity of floaters can vary.

4.
Floaters can appear at any time, so please try to relax and not overly concern yourself.
Most cases of floaters are a normal degenerative phenomenon of the vitreous body and are unrelated to the retina.

Hello! Thank you for your detailed question regarding your eye fatigue and the symptoms you are experiencing. It sounds like you have been dealing with a complex set of issues, and I appreciate your patience as we explore them.

1. Light Sensitivity (Photophobia): The light sensitivity in your right eye could be due to several factors. It may be related to the fatigue of the ciliary muscle, which is responsible for focusing your vision, especially when looking at screens for prolonged periods. This muscle can become strained, leading to discomfort and sensitivity to light. In some cases, dry eyes can also contribute to light sensitivity, as they can cause irritation and discomfort. It's essential to ensure that your eyes are adequately lubricated, especially if you are spending long hours in front of screens. Artificial tears can help alleviate dryness and discomfort.

2. Increased Visibility of Floaters: Floaters are tiny specks or strands that float in your field of vision. They are usually harmless and are a common occurrence as we age. However, if you notice an increase in the number or visibility of floaters, especially if they are accompanied by flashes of light or a shadow in your peripheral vision, it is crucial to consult an eye specialist. The fact that you have undergone dilated fundus examinations and your retina has been deemed normal is reassuring. However, the perception of more floaters, particularly in low-light conditions, can be exacerbated by fatigue or strain on your eyes. When your eyes are tired, they may be more sensitive to visual disturbances, making floaters more noticeable.

3. Colored Floaters: The presence of colored floaters, such as the darker ones you described, can be concerning but is not uncommon. Floaters can appear darker or more pronounced against bright backgrounds or in certain lighting conditions. However, if you notice a sudden increase in floaters or changes in their appearance, it is essential to follow up with your eye doctor to rule out any underlying issues.

4. Eye Fatigue and Floaters: It is indeed possible that the fatigue you are experiencing is contributing to the increased visibility of floaters. When your eyes are overworked, they may not function optimally, leading to heightened awareness of visual phenomena like floaters. Additionally, prolonged screen time can lead to digital eye strain, which can exacerbate symptoms like discomfort, dryness, and sensitivity to light.

In summary, your symptoms of light sensitivity, increased floaters, and discomfort while watching television could be interconnected and may stem from eye fatigue, dryness, or strain. It is crucial to take regular breaks from screens, practice the 20-20-20 rule (every 20 minutes, look at something 20 feet away for 20 seconds), and ensure your eyes are adequately lubricated. If your symptoms persist or worsen, I recommend seeking further evaluation from an eye care professional who can provide personalized advice and treatment options.

Thank you for your questions, and I hope this information helps clarify your concerns! Please take care of your eyes, and don’t hesitate to reach out for further assistance.
