Why do I see numerous black dots when I look at the sky?


I have approximately 500 degrees of myopia in both eyes.
I previously noticed that I might have floaters.
Normally, when I'm reading, writing, or using my phone, I don't see them much, but whenever I go outside or see sunlight, I notice one or two "bugs." When I look at the sky, they appear as small moving black dots, but they are not very noticeable.
After looking for a while, I can see the black dots more clearly, but they are all small.
Why does this happen?

Hello: These dark spots are also substances floating in the vitreous body, which is a type of floaters.

More Info


Seeing floating black spots in your vision, especially when looking at a bright sky, is a common experience known as "floaters." These floaters are typically small clumps of gel or cells that form in the vitreous humor, the clear gel-like substance that fills the inside of your eye. As we age, the vitreous humor can become more liquid and shrink, leading to the formation of these floaters. They can appear as tiny dots, lines, or cobweb-like structures that drift around in your field of vision, particularly noticeable against a bright background like the sky.

In your case, with a prescription of approximately 500 degrees in both eyes and a history of myopia (nearsightedness), you may be more prone to experiencing floaters. Myopia can increase the risk of changes in the vitreous humor, which may lead to the development of floaters. When you look at a bright light source or a clear sky, the contrast makes these floaters more apparent, which is why you notice them more in those situations.

The phenomenon you describe, where the floaters seem to move or become more noticeable when looking at the sky, is quite normal. Floaters are usually harmless and do not require treatment unless they significantly interfere with your vision or are accompanied by other symptoms, such as flashes of light or a sudden increase in the number of floaters, which could indicate a more serious condition like a retinal tear or detachment.

If you have previously had a thorough eye examination, including a dilated fundus examination, and your retina was found to be healthy, it is likely that your floaters are benign. However, if you notice any changes in your vision, such as a sudden increase in floaters, flashes of light, or a shadow or curtain effect in your peripheral vision, it is crucial to seek immediate medical attention from an eye care professional.

In summary, the small black dots you see in the sky are likely floaters caused by changes in the vitreous humor of your eyes. While they can be bothersome, they are generally harmless. Regular eye check-ups are essential, especially with your history of myopia, to monitor your eye health and ensure that no other issues arise. If you have any concerns or notice changes in your vision, do not hesitate to consult with your eye doctor for further evaluation and peace of mind.
