Eye floaters - When should you be concerned?
If you are looking against a bright background you might see in your visual field tiny specks and wriggly objects appearing like a thread or an insect and these are called floaters.
What are floaters?
Floaters and spots are just tiny pieces of the vitreous. This is the part of the eye between the lens and the retina that occasionally break loose within the inner back portion of the eye. What you see as floaters are not the pieces themselves, but their shadows cast on the retina.
Eye flashes are caused when the retinal nerve fibres gets stimulated. This can happen through mechanical stimulation like when you get hit in the head or when the retina is torn or detached from the back of the eye.
Floaters are more common in people with negative power/myopia and increases as we age.
