I'm 19 now, but since as far back as I can remember, I've always been able to look into the sky during bright daytime (opposite section of the sky than the sun (I'd feel silly to report visual distortions while looking near the sun)) or another bright color surface in a bright setting (rarely, it's usually only the sky during the day) and see a circular area of shaded, random formations moving towards the center of the circle, but with a smaller, concentric circular area of clear vision (middle is clear). The outer circle is about as big as the area my hands make when I put my index and thumb fingers together and outstretch my arms in front of me (all according to perspective, of course, but it should give you a good general idea). The inner circle is about a half inch in diameter at arm's length (width of your thumb outstretched in front of you). The objects have no specific detail, but when I was younger I related them to horse pills (long story). The formations are very faint and cause no blurred or reduced vision. They seem to start at the outer edge and fall into the center. I don't immediately see the formations, but the formations become more prominent as I allow my eyes to adjust to the brightness.
Think of a traditional vortex portal out of a sci-fi tv-show or movie, and then think of the Stargate portal. The dark formations in my vision seem to be fluid with each other, like the shaded areas of the Stargate portal, and they all seem to be flowing towards the center as in a vortex. The formations move and change rather rapidly, so I cannot accurately describe them.
Again, I'm 19, but have been experiencing this for as long as I can remember. I have 20/20 in one eye and 20/16 in another, but it happens to both eyes anyway. I have no chronic or childhood illnesses and, more or less, a lack of acute illnesses. My mother has astigmatism and gets the halos around lights at night, as does my dad (the halos). I get small to medium flares on lights at night, not prominent enough to disturb normal activity. I received a concussion by falling head first on the ground in a sand-based playground when I was 7, but I’m pretty sure I’ve had these distortions since before then.
Weird, huh? I've looked over multiple sites that list eye/vision symptoms and illnesses, and nothing looks remotely like what I'm experiencing. My father's only guess is that my irides (irises) are slightly translucent so I see light passing through the tissue of my irides onto my retinas. The shape of the distortion seems to resemble an iris, so I figured I'd look into it, but I can't find anything on irides having the ability to be translucent. The closest thing I've found is Atypical Anirida, which is a underdevelopment of the iris. In most cases of Aniridia, the iris isn't visible on the eye and the pupil takes up nearly all of the space, but in an "atypical" case, "The iris may appear normal but it may be thinner than normal." - anirida.org
Any of you have any feedback? Have you heard of anything like this before?
