Seeing Shadows After Waking Up: Eye Floaters and Health Tips - Ophthalmology

Seeing small dark shadows after waking up?


Hello Doctor, after taking a nap today, I noticed that my eyes seemed a bit blurry and I saw something like fruit flies flying by quickly, but later I wasn't sure if I actually saw them.
Last week, I went to the ophthalmologist and had a fundus examination, which showed that everything looked normal with no signs of tears or bleeding.
It’s possible that what I saw was just real insects or maybe it’s related to floaters.
The doctor mentioned that if I experience flashes of light or see a lot of floaters, I should come back for a check-up.
However, does that mean I would see a flash of light in front of my eyes? Should I go for another examination, or is this not a flash sensation? My family says I shouldn’t worry too much, but I also thought I saw fruit flies on the bamboo shoots in the living room, and I’m not sure if it was the same one I saw earlier.
😅 Additionally, my grandmother has been telling me to eat more carrots...
but I feel like this might be a folk remedy.
Does eating more carrots really have protective benefits? I originally didn’t like them, but I’ve been having them at dinner every night lately...
it’s a bit confusing, and I’d like to ask for your advice, Doctor! Thank you.

Hello Piko: The flashes you are experiencing are similar to lightning during a thunderstorm, not like fruit flies.
This condition may persist for a long time, and if there is no tear in the retina, there is basically no treatment available.
If the examination showed no issues, you should feel reassured.
The ophthalmology department at Puzih Hospital in Taiwan is open: Monday, Tuesday, Thursday, and Friday from 8:00 AM to 12:00 PM, and Wednesday from 2:00 PM to 4:30 PM.
Online responses can only serve as a reference; if necessary, you should still seek medical attention at a healthcare facility.
I hope to have the opportunity to serve you.

Hello! It sounds like you're experiencing some common visual phenomena that many people encounter, particularly related to eye floaters and possibly some light sensitivity. Let's break down your concerns and provide some insights based on medical knowledge.

Firstly, the "seeing shadows" or "seeing something like fruit flies" that you described after waking up is likely related to a condition known as floaters. Floaters are tiny clumps of gel or cells that form in the vitreous humor, the clear gel-like substance that fills the eye. As we age, the vitreous can become more liquid, and these floaters can become more noticeable, especially in certain lighting conditions or when looking at a plain background. They can appear as spots, threads, or even cobweb-like structures that drift across your field of vision.
The fact that your eye examination showed no signs of retinal tears or bleeding is reassuring. However, if you notice an increase in the number of floaters, especially if accompanied by flashes of light (which are often described as "lightning streaks"), it is important to seek further evaluation. These symptoms can indicate a more serious condition, such as a retinal detachment, which requires immediate attention.

Regarding your question about whether you need to go for another check-up, if the floaters are stable and you are not experiencing any new symptoms (like flashes of light or a curtain-like shadow over your vision), it may not be necessary to rush back to the doctor. However, if you feel uncertain or if your symptoms change, it is always best to consult with your eye care professional for peace of mind.

As for the advice from your grandmother about eating more carrots, this stems from the belief that carrots can improve vision due to their high beta-carotene content, which the body converts into vitamin A. Vitamin A is essential for maintaining good vision, particularly in low-light conditions. While eating carrots can contribute to overall eye health, they are not a cure-all for vision problems. A balanced diet rich in various nutrients, including leafy greens, fish, and fruits, is more beneficial for eye health than focusing solely on one food item.

In summary, while floaters are generally harmless, keeping an eye on any changes in your vision is crucial. Regular eye exams are essential, especially if you have a history of eye issues or if you experience any new symptoms. Eating a healthy diet can support your overall eye health, but it should be part of a broader approach to wellness. If you have any further concerns or if your symptoms persist, don't hesitate to reach out to your eye care provider for further evaluation. Take care!
