The sensation of seeing mosquitoes with the eyes?
Hello, doctor.
Recently, I went to have my eyes checked because I sometimes see floaters.
The eye doctor said I only have vitreous floaters and no tears, so I shouldn't worry and just observe.
However, just now while using my phone, I suddenly saw something that looked like a mosquito flying by, but I'm not sure if it was an insect; the speed was quite different from the floaters I usually see.
I would like to ask if such a situation can occur, or if it was probably just an insect passing by.
Additionally, although I have undergone a dilated eye exam with no issues, I still occasionally notice the floaters drifting.
Will they improve over time? Sometimes, when I check my eyes using a grid online, I don't see any distortion, but when I close one eye and switch to the other, it can be blurry for about 1-2 seconds.
Is this a normal physiological phenomenon? Thank you for addressing these questions.

Hello Lin: After the dilated eye exam, everything seems fine, so you should feel reassured.
However, the floaters may persist for a long time and may not disappear.

It is normal for your vision to be blurry for 1-2 seconds when switching eyes while closing one eye.
This can happen because sometimes the eyelid exerts pressure on the cornea, and once the cornea recovers, your vision will clear up.
At the E-Hospital in Puzi, Taiwan, the ophthalmology department 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 visit a medical facility for treatment.
I hope to have the opportunity to serve you.

When it comes to understanding floaters and other eye symptoms, it's essential to differentiate between normal occurrences and those that may indicate a more serious condition. Floaters, or "muscae volitantes," are tiny specks or strands that drift through your field of vision. They are often more noticeable against a bright background, such as a clear sky or a white wall. While they can be annoying, floaters are usually harmless and a common occurrence, especially as we age.
From your description, it seems you have already consulted with an eye doctor who diagnosed you with floaters but found no retinal tears or other significant issues. This is reassuring, as retinal tears or detachments can be serious and require immediate attention. The fact that your doctor advised you to observe the floaters without concern suggests that they are likely benign.
Regarding your recent experience of seeing something that resembled a mosquito flying by, it is possible that what you saw was indeed a small insect. The speed and nature of what you observed could differ from the floaters you typically see. Floaters tend to move slowly and are influenced by your eye movements, while an insect would move more quickly and erratically. If the appearance of this "flying object" was fleeting and did not recur, it is likely nothing to worry about.
As for the floaters you occasionally see, it is important to note that they may not completely disappear. Many people who have floaters learn to live with them, and while they may become less noticeable over time, they often do not go away entirely. If your floaters change in appearance, increase in number, or are accompanied by flashes of light or a sudden loss of vision, you should seek immediate medical attention, as these could be signs of a more serious condition.
The phenomenon of experiencing brief blurriness when switching between eyes is generally considered a normal physiological occurrence. This can happen due to differences in focus or light adaptation between your eyes. If you notice that this blurriness lasts longer than a couple of seconds or is accompanied by other symptoms, such as pain or significant vision changes, it would be wise to consult your eye doctor.
In summary, while floaters are typically benign, it's crucial to remain vigilant about any changes in your vision. Regular eye exams are essential, especially if you have a history of high myopia or other eye conditions. If you ever feel uncertain about your symptoms or if they change, don't hesitate to reach out to your eye care professional for further evaluation. Maintaining open communication with your healthcare provider will help ensure your eye health remains a priority.
