The white wall is not entirely white; there are shadows?
Hello Doctor: In recent years, whenever I look at completely white walls, I feel like there are black shadows flickering, or I experience a sensation similar to low-resolution video with black specks.
I would like to ask if this could be a symptom of floaters.
I have a history of floaters, with a prescription of -3.00 to -4.00 diopters and astigmatism of -1.00 to -2.00 diopters.
Two weeks ago, I underwent a dilated fundus examination, and the results showed no tears, detachment, or bleeding.
At that time, I also consulted the doctor, who said there were no issues and mentioned that my condition falls within the range of floaters.
However, I still feel anxious about it.
Recently, I have been using my eyes excessively, and I wonder if that could have an impact.
Thank you, Doctor.

Hello Wei: This situation is likely a manifestation of floaters.
If you have already undergone a dilated eye examination and everything is normal, you can rest assured.
However, it's important to give your eyes plenty of rest to prevent the floaters from worsening.
In Taiwan, the ophthalmology department at Puzi Hospital is open on Monday, Tuesday, Thursday, and Friday mornings from 8:00 AM to 12:00 PM, and on Wednesday afternoons from 2:00 PM to 4:30 PM.
Please note that online responses are for reference only; if necessary, you should seek medical attention at a healthcare facility.
I hope to have the opportunity to serve you.

Hello! Thank you for reaching out with your concerns regarding your visual disturbances. Based on your description, it seems that you are experiencing symptoms consistent with floaters, which are common among individuals with myopia (nearsightedness) and can be exacerbated by eye strain or fatigue.
Floaters are tiny spots, lines, or cobweb-like shapes that drift through your field of vision. They are caused by changes in the vitreous humor, the gel-like substance that fills the eye. As we age, the vitreous can become more liquid and may pull away from the retina, leading to the perception of floaters. In your case, since you have a history of myopia and have already been diagnosed with floaters, it is likely that what you are experiencing is related to this condition.
The fact that you have undergone a dilated eye exam and that your retina was found to be intact without any tears, detachment, or bleeding is reassuring. It suggests that there are no acute issues with your retina, which is a common concern when floaters are present. Your eye doctor’s assessment that your symptoms fall within the realm of floaters is consistent with your description.
However, it is important to note that while floaters are usually harmless, any sudden increase in the number of floaters, especially if accompanied by flashes of light or a shadow in your peripheral vision, should prompt immediate medical attention. This could indicate a more serious condition, such as a retinal tear or detachment.
Regarding your concerns about eye strain, it is indeed possible that excessive screen time or prolonged near work can lead to visual fatigue, which may exacerbate the perception of floaters. When you focus intently on a screen or a book, your eyes may become fatigued, and this can make floaters more noticeable. To mitigate this, consider implementing the 20-20-20 rule: every 20 minutes, take a 20-second break to look at something 20 feet away. This can help reduce eye strain and improve comfort.
Additionally, maintaining proper lighting while reading or using screens can also help reduce strain. Ensure that your workspace is well-lit and that you are using appropriate eyewear if prescribed. If you find that your symptoms persist or worsen despite these adjustments, it may be beneficial to revisit your eye care provider for further evaluation.
In summary, based on your description and the results of your recent eye examination, it seems that your symptoms are likely related to floaters, which are common and generally benign. However, if you experience any new or concerning symptoms, do not hesitate to seek further evaluation. Regular eye check-ups are essential, especially for individuals with myopia, to monitor any changes in your eye health. Thank you for your question, and I hope this information helps alleviate some of your concerns!
