Shadow vision refers to the experience of seeing small spots or shadows that drift around aimlessly in your field of vision, casting slight shadows on your retina. These shadows are commonly known as eye floaters. They are made up of the vitreous, a clear gel-like material that fills most of the eye.
In other words, shadow vision, as perceived by many, is actually the presence of floaters – small, dark shapes that appear to float across your field of vision.
Understanding Eye Floaters and "Shadow Vision"
Eye floaters, the cause of the subjective experience of "shadow vision," are typically harmless, especially if they appear gradually over time.
What are Eye Floaters Made Of?
According to the provided reference, eye floaters are made up of the vitreous.
Common Characteristics of Floaters:
- They appear as spots, threads, or cobwebs.
- They seem to drift around when you move your eyes.
- They are most noticeable when looking at a bright, uniform background (like a blue sky or a white wall).
- They cast slight shadows on the retina, causing the sensation of "shadows" in your vision.
When to Seek Medical Attention:
While most floaters are harmless, a sudden increase in the number of floaters, especially if accompanied by flashes of light or a loss of peripheral vision, could indicate a more serious condition, such as a retinal detachment. Consult an eye care professional immediately if you experience these symptoms.
