|Eye "Spots" or "Floaters"|
You can often see
or spots when looking at a plain background, like a blank wall or blue sky.
Floaters are small |
clumps of condensed protein or cells that form in the vitreous,
the clear fluid that fills the interior cavity of the eye. Vitreous
is 99% water and similar in appearance to clear Jell-O.
Floaters may appear as specks, strands, webs or other shapes moving into your field of vision. You don't see the floater itself
but it's shadow cast onto the retina, the light sensitive film at the back of the eye.
Since the floater is within your eye, and moves with it, any effort to look directly at
the floater causes it to constantly "run away" as your eye turns.
Flashes of light lasting a few seconds may appear in your vision when the vitreous gel pulls or tugs on the retina. This may happen as a natural result of aging or it may occur temporarily if you receive a blow to the head or eye. Usually these flashes, which are often described as lightning streaks, are noticed at night.
The onset of new light flashes of short duration at night, especially when accompanied
by the appearance of many new floaters or a blackening out of part of your field of vision, may indicate a retinal tear or detachment. If you experience light flashes in combination with these symptoms, you should contact your eye doctor immediately.
Migraine - Some people experience flashes of light that appear as jagged lines or "heat waves" in both eyes, often lasting 10-20 minutes. These types of flashes are usually caused by a spasm of blood vessels in the brain, which is called a migraine. If a
headache follows the flashes, it is called a migraine headache. However, jagged lines or "heat waves" can occur without a headache. Migraine-related flashes are often noticed
in a lighted environment. Flashes of this nature are not a symptom of eye problems. If you suffer from ocular migraines, contact your general physician for assistance.
