| What
Are Flashes? |
| Have
you ever seen flashes of light, stars, or streaks that aren't really
there? A few of these flashes are seen by everyone from time to
time. Usually you see them in one eye at a time. Flashes are
often caused by the vitreous (the gel filling the inside of your eye)
pulling on the retina (a membrane that lines the inside of your eye). |
 |
Who
Gets Flashes?
As you age or if you are nearsighted
(have fuzzy distance vision), you are more likely to see flashes.
Sometimes, flashes are signs of other eye problems that need care. |
| What
Are Floaters? |
| Floaters look like dark specks,
clouds, threads, or spider webs moving through your vision. Most
people see them once in a while. Floaters may be pieces of gel or
other material floating inside your eye. They are usually
harmless. |
 |
Who
Gets Floaters?
The older you get, the more likely you'll
notice floaters. Floaters can also be caused by an eye injury or
surgery. If floaters appear suddenly or greatly increase in
number, they may be a sign of an eye problem that needs care. |
| Are
Flashes and Floaters Serious? |
| Most
often, seeing a few flashes and floaters is normal. Also, some
people may notice them for a while after eye surgery. Most flashes
and floaters require no treatment. But sometimes they can be signs
of a serious eye problem. To find out, you may need an eye exam. |
| Who
Should Get an Exam?
See your eye doctor if you notice any of
the following symptoms.
- You have never seen flashes or
floaters before and all of a sudden you see a lot of them.
- You've seen some flashes or floaters
before, but you have a sudden increase in the number you see.
- You've seen some flashes or floaters
for a long time, but the now look different than they used to.
- Flashes or floaters make it hard to do
your normal tasks.

Your
Eye Exam
Your eye doctor can check your eyes to be
sure the flashes or floaters are not signs of a more serious eye
problem. At an exam, your doctor will:
- Ask you questions. Knowing
about your health and your family history of eye problems helps your
doctor learn if you're likely to have eye problems.
- Test your vision.
- Examine your eyes. Your
doctor may dilate your pupils and use special instruments to see
inside your eyes.

| When
Do Flashes Need Treatment? |
When
Do Floaters Need Treatment? |
| Flashes
that appear all of a sudden or greatly increase in number may be a sign
of a problem. They may be caused by the vitreous pulling too hard
on the retina. This can make the retina tear or detach from the
back of the eye. Rapid vision loss can result. Your eye
doctor can find the causes of flashes and decide if treatment is needed. |
A
sudden increase in the number of floaters you see may be a sign of a
tear in the retina or of some other eye problem. Over time, a tear
can cause the retina to detach from the back of the eye. Your eye
doctor can find out what is causing the floaters and suggest a treatment
plan, if needed. |
| It's
Up to You |
| The
older you get, the more flashes and floaters you may see. They are
usually harmless. But if you suddenly notice more of them, it may
be a sign of an eye problem that needs care. Get regular eye exams
to be sure that your flashes and floaters are normal and to protect and
preserve your vision.
