What are they?!
Question:
What are they?
Anyone ever look up at a light and see shapes moving? Almost as if you are seeing the shapes through your eyes or perhaps they are even IN your eyes? Are those blood cells you are seeing or something?
Answers:
More than likely you are referring to vitreal floaters, they are located inside the eye within a jelly-like substance called the vitreous humour. With time, this gel starts to break down and gets a little more liquid-like. When molecules floating in this gel hit, they begin to clump together and form minute strands that cast shadows on the retina that you perceive as little shapes.
For the most part, these are benign and there is no sensible/safe treatment for them...eventually the brain just tunes them out.
However, if this is of recent onset and is asociated with flashes of light, lightening bolts in your vision, the appearance of a curtain or vale over your vision, this could signs of a retinal detachment which is a serious eye emergency and you should see an eye doctor at once.
Depending on your age, it could be a PVD (posterior vitreal detachment). This typically happens later in life around your 50's and isn't as severe as other types of retinal detachments. Here's some more info on PVD's:
