Eye Issues: Are Those Yellow Spots Floaters? - Ophthalmology

More Info

---

The phenomenon you're experiencing, where you see yellow spots on white tiles when the lights are turned on, is not typically classified as floaters (or "vitreous floaters"). Floaters are small, shadowy shapes that can appear in your field of vision, often described as dots, circles, or cobweb-like strands. They are caused by tiny pieces of gel or cells inside the vitreous, the clear gel-like substance that fills the eye, casting shadows on the retina as they move.

What you are describing sounds more like a visual phenomenon related to the way your eyes adapt to changes in light. When you move from a dark environment to a brightly lit one, your eyes undergo a process called "light adaptation." This involves the contraction of the pupil and changes in the photoreceptor cells in the retina, which can sometimes lead to temporary visual disturbances, such as seeing spots or colors that are not actually present in the environment.
The yellow spots you see could be a result of several factors:
1. Afterimages: When you look at a bright light or a white surface, your photoreceptors can become overstimulated. Once you shift your gaze, you might see a temporary afterimage, which can appear as colored spots or shapes.

2. Visual Snow: Some individuals experience a condition known as visual snow, where they see persistent tiny dots or "snow" in their vision, particularly in low-light conditions or when transitioning to bright light.

3. Retinal Issues: Although less likely given your description, any sudden changes in vision, especially if accompanied by other symptoms like flashes of light or a significant increase in floaters, should be evaluated by an eye care professional to rule out any serious conditions such as retinal detachment or other retinal disorders.

4. Migraine Aura: If you have a history of migraines, you might experience visual disturbances known as aura, which can include spots, zigzag lines, or other visual distortions.

5. Eye Fatigue or Strain: Prolonged periods of focusing on screens or reading can lead to eye strain, which may cause temporary visual disturbances.

Given that the yellow spots disappear after a few seconds as your eyes adjust, it is likely a benign phenomenon related to light adaptation rather than floaters. However, if you notice any persistent changes in your vision, or if the spots become more frequent or bothersome, it is advisable to consult with an eye care professional. They can perform a comprehensive eye examination to ensure that your eyes are healthy and rule out any underlying conditions.

In summary, while your experience of seeing yellow spots on white tiles when the lights are turned on is not typical of floaters, it is important to monitor your vision and seek professional advice if you have any concerns. Regular eye check-ups are essential for maintaining eye health and addressing any potential issues early on.
