Weather and Eyes
Why is it that on cold days, or early in the morning or
late in the afternoon when I look up towards the sky I see little white
dots moving all around, the best way to describe them would be tiny
molecules about the thickness of an arm hair or smaller. I see a lot of
them and moving in all different directions and when I blow out air in
front of me I can see how they react. I thought about capturing this on
my cam. but they won't show up, Is there any one out there that see this
also and wonders what they are? air molecules, particles or somethings
else because when I told my girlfriend she though that I'm crazy or that
there's something wrong with my vision. I could swear that these things
are real and they are not dust but tiny white/semi-clear dots moving in
all direction and reacting to the wind. Is it posible for us to see these
particles with our eyes?
The time of day/night that you observe these particles I think has to do
with the intensity of incident light. If the light is bright enough, the
effect is "washed out".
I believe that these "dots" are natural sloughing off of cells within
the eye. In that case you would not capture them with a video cam.
The cells move around depending upon the movement of your eye, which
changes the flow of fluid within the eye. Yes, these are real, but if they
cause you concern, you should have an ophthalmologist "check them out". I
don't think they are serious and I think many people experience the same
observation (i.e. I have).
