As we get older we expect to have problems with our eyes, so we tend to ignore them. One minor symptom that can cause a bigger problem if it's not treated is the occurrence of floaters and flashers, those tiny lights that seem to blink through your vision and that you can never catch when you direct your focus toward them.

Almost everyone sees floaters at some time, but they can occur more frequently and become more noticeable as we get older.

Floaters caused by posterior vitreous detachment are more common in people who:
Are nearsighted
Have undergone cataract surgery
Have had certain types of laser surgery
Have had inflammation of the eye

Because floaters or flashes can be an indication of a serious problem, you should our doctor when:
You see floaters for the first time
You notice an increase in the number or size of floaters
You experience the sudden onset of flashes

In most cases, no serious problems are found, but a complete eye examination is important. If there is damage to the retina, it needs to be diagnosed and treated immediately to prevent vision loss.
