what does it mean when your left eye jumps?

When any of your muscles jump, they are spasming.  There is a saying - if it spasms, feed it magnesium.  You have four major minerals in your body: calcium, potassium, sodium and magnesium that need to be in balance.  Magnesium has a function in transmitting nerve impulses - I think of it like having insulation over an electrical wire - like the one to a light bulb.  Without the insulation (or with low magnesium) your nerve impulses jump around the room (or your body) and cause spasming.\n\nTake 500mg to 1000 mg magnesium at night and see if it helps.  It should also help relax you and help you to sleep better.

Hmmm, could be different things.  \n\nGenerally flashes can be one whole thing.  One way this happens is when blood is rushing out of the head to other parts of the body(Like when someone is about to faint).  Standing up really fast after sitting a long while you can see dots of light floating around like a cartoon character would see stars after getting hit on the head with a mallet.\n\n"Floaters" can be a whole other.  Whenever you stare at bright light, temporarily part of your vision will "turn off" to protect itself.  Then you'll have a little black spot(or a while spot in the dark) floating around like bug.  Sometimes they can be permanent(in extreme cases, like staring at a solar eclipse), but usually for other medical reasons.\n\nThose are just examples, but there are lots of reasons why you can see odd things in your vision.  For example, I have strabismus(crossed eyes).  When an eye tries to jerk to one side really fast I sometimes see a black splotch in my vision for a second.  I've been told that's because the fast jerk is pulling the optic nerve on the back of my eye.  And the splotch is the back of the nerve on the retina(the "movie screen" part of your eye).\n\nWell, these are just examples.  But yea, go see a doctor.  I bet insurance would cover it and you won't lose anything.  Even if you've had this problem for years, it could get worse.  You never know.\n\n(Just if anyone was curious: I did have crossed eyes, but I had surgery to correct it cosmetically.  However, crossed eyes are not caused by the eye muscles being defective but by a lack of control of them.  It is more of a palsy because eye training can't completely "fix" the problem.  Cutting the muscle to weaken them does mask the "jerky" control, thereby giving cosmetically straight eyes.)

We do not know exactly why this happens, but it might reflect a "crossing" of pathways in the brain, between the normal reflex of the eye in response to light and the sneezing reflex.\n\nClick below for a FULL explination

Your are probably referring to a spasm or what is referred to as a "tic".  It is caused by eye strain or nervousness. If you are a student, you  may be studying too hard or staying up too late.  Try to relax and take short breaks from your books or the computer to refresh your eyes. This is not a serious condition and will go away on its own but if it becomes persistant, check with the schooll nurse or your doctor for medical advise.

It's called saccations when your eyes jump. Saccations are short leaps across the words. This happens because your eyes can recognize words faster than your brain interprets them. I do the same thing (lose my place) sometimes, but it's normal. It has connections with speed reading. We studied this in one of my classes last semester.

Usually people with lazy eye (strabismus) ignore (suppress) the eye that isn't pointed where they're looking.  The brain doesn't like to get conflicting information from the two eyes, so if it does, it only pays attention to one.

Yes, there is an operation in which they detach and reattach the muscles that move the eye. It is a very simple and quite common procedure, however you may have a type of lazy eye that is more akin to epilepsy and this is brought on by stress or fatigue. The operation is probably covered by most health insurance.

Another reason could be you have simply had too much caffeine and/or not enough sleep.  If I drink too much coffee and eat chocolate, my eye twitches.

The ciliary muscles of the pupil allows them to dilate (called mydiasis) or constrict (called miosis) in responding to the amount of light in your environment. A number of things might cause the pupils to dilate. The most common reason would be low levels of light..the pupils dilate to let more light in. In the absence of low light, some reasons might be certain drugs, increased intracranial pressure (trauma, neoplasm), and reduced blood flow to the brain. Often, if only one pupil is dilated it could be from a stroke or lesion affecting crainial nerves II or III, or from paralysis of the ciliary muscle due to trauma. Also, anything that causes activation of the sympathetic nervous system (e.g. "fight or flight" response) will result in dilated pupils. Sometimes however, there is no clear cut reason. If you notice a change you should definitely go to your doctor and get it checked out.

Occasionally, your eye may twitch at random. This involuntary twitching of the eyelid muscle usually lasts less than a minute. But it can be bothersome. The cause of eyelid twitching isn't known. However, it's often associated with fatigue and stress. You may be able to relieve the twitching by gently massaging the affected eyelid.\n\nAn eyelid twitch is usually harmless. Rarely, a twitching eyelid can be a symptom of a muscle or nerve disease. But if that is the case, it's usually accompanied by other symptoms.

I have the same stuff near my left eye. It's some small pocket of adipose (fatty) deposits. A doctor friend of mine has suggested that it may be due to an increase in cholesterol level that results in this fatty deposits. It clings on for years. The only effective way of removing it without causing any scars would be to see a cosmetic surgeon.

ooh- i have that happen every now and then too. it tells you that you are being deprived of a certain mineral-Vitamin C, for instance. (that may not be it, but it very well could be). the only way to make it stop twitching is to get whole, hearty foods for the next couple of days, making sure to get all of your vitamins and minerals in.

Its probably just a habit now.  The only concern would be developing a lazy eye...the one that is not being used.  You should try to force yourself to use the other...and maybe you are not using it for a reason...i.e. you can't see well out of it...so see an eye Dr.

An eyelid twitch can be caused by fatigue, stress, or even caffeine. They can continue on and off for days and will eventually stop. \n\nRelax, cut the caffeine intake and relax.

It means you are really tired and run down. I get that when Im stressed or what I just said. Like the eyelashes kind of twitch. Anyway, get some vitamins and some sleep!
