Floaters: Why Do You See Spots on White Walls? - Ophthalmology

More Info

Floaters, often described as "flying spots" or "cobwebs," are a common visual phenomenon experienced by many individuals, particularly as they age. These floaters are typically 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 formation of these floaters. They can appear as small dots, lines, or cobweb-like structures that drift across your field of vision, especially against bright backgrounds like white walls or clear skies.

In your case, it sounds like you have been experiencing floaters for about three years, and you have noticed that your vision is not as clear when looking at white walls. This could be due to the contrast between the floaters and the bright background, making them more noticeable. The perception of floaters can vary depending on lighting conditions; they are often more prominent against a light background, such as a white wall or the blue sky, which may explain why you see them more clearly in those situations.

It's important to note that while floaters are usually harmless, a sudden increase in the number of floaters, especially if accompanied by flashes of light or a shadow in your peripheral vision, can be a sign of a more serious condition, such as a retinal tear or detachment. If you experience any of these symptoms, it is crucial to seek immediate medical attention from an eye care professional.

Regarding your observation of seeing "small light points" moving around in the sky, this could also be related to the floaters. The movement of these spots can be influenced by your eye movements, as they tend to drift in the opposite direction of your gaze. This is a normal characteristic of floaters and is not usually a cause for concern.

If you are finding that your floaters are significantly impacting your daily life or causing distress, it may be worth discussing with an ophthalmologist. They can perform a comprehensive eye examination to ensure that your eyes are healthy and that there are no underlying issues contributing to your symptoms. In some cases, if floaters are particularly bothersome, there are treatment options available, such as vitrectomy or laser therapy, although these are typically reserved for severe cases due to the associated risks.

In summary, floaters are a common visual phenomenon that can become more noticeable against bright backgrounds. While they are usually harmless, any sudden changes in your vision warrant a visit to an eye care professional to rule out any serious conditions. Maintaining regular eye check-ups is essential for monitoring your eye health, especially as you age.
