Flashes of light in the eyes?


Hello, Doctor.
I have floaters in my vision.
About a month ago, I had an eye examination, and the doctor said my eyes were fine and advised me to watch for any flashes of light.
However, today while I was writing, I noticed orange flashing spots on the white paper, which moved a bit, and then after about one or two seconds, a dark spot appeared.
I usually stare at walls or white paper and have never experienced this issue before, so I would like to ask if I should get checked again or if this is not a problem.
Should I just wait and see if it resolves on its own? Also, is it true that floaters can be related to liver issues? I have seen many websites claiming this.
I feel that my eyes are slightly yellow, and I often stayed up past midnight during middle school.
Could this be the reason for my floaters? If I consult a traditional Chinese medicine practitioner, would it be helpful, or would it be sufficient to just go to bed earlier and reduce screen time?

Floaters are not directly related to liver function.
Generally, if they occur, they do not resolve on their own.
If there are persistent flashes of light, it is advisable to undergo a thorough examination.
If it only happens once, then observation is sufficient.

Understanding eye flashes and floaters is crucial for maintaining eye health, especially for individuals who already experience symptoms like floaters. Based on your description, it seems that you have been experiencing new visual disturbances, specifically orange flashes and dark spots, which can be concerning.
Firstly, it is essential to understand that flashes of light in the vision, particularly when associated with floaters, can indicate a potential issue with the retina. Flashes often occur due to the vitreous gel in the eye pulling on the retina, which can happen as the vitreous shrinks with age or due to other factors. If this pulling is significant, it can lead to retinal tears or detachment, which is a serious condition that requires immediate medical attention.
Given that you have noticed these flashes while focusing on a white surface, it is advisable to seek a follow-up examination with an eye care professional, especially since you have a history of floaters. Even though your previous examination indicated no issues, new symptoms warrant a re-evaluation. An eye doctor can perform a thorough examination, including a dilated fundus exam, to assess the retina's condition and rule out any serious problems.

Regarding your concern about floaters being related to liver health, there is no direct scientific evidence linking floaters to liver function. Floaters are primarily caused by changes in the vitreous humor, which can occur with aging, myopia (nearsightedness), or other eye conditions. While some alternative health sources may suggest a connection between liver health and eye conditions, it is essential to rely on evidence-based medicine. If you are experiencing yellowing of the eyes (jaundice), this could indicate liver issues, and you should consult a healthcare provider for a comprehensive evaluation.

Your history of late nights and excessive screen time may contribute to eye strain and discomfort, but they are not directly linked to the development of floaters. However, maintaining good eye hygiene, such as taking regular breaks from screens (the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds), ensuring proper lighting while reading or working, and getting adequate sleep, can help reduce eye strain and improve overall eye comfort.

As for traditional Chinese medicine (TCM), some individuals find it beneficial for general wellness and eye health. Acupuncture and herbal remedies may help alleviate symptoms of eye strain or fatigue, but they should not replace conventional medical evaluations, especially when experiencing new or concerning symptoms like flashes or changes in vision.

In summary, it is crucial to monitor your symptoms closely. If you experience any new flashes, especially if they are accompanied by a sudden increase in floaters, a curtain-like shadow in your vision, or a significant change in your eyesight, seek immediate medical attention. Regular eye check-ups are vital, especially if you have pre-existing conditions like floaters. Lastly, while lifestyle changes can support eye health, they should complement, not replace, professional medical advice and treatment.
