all computer monitors blink, and soo fast that you dont really notice. This is why your eyes get sore after staring the the screen for a long time. Maybe your settings are soo low that you can actaully see it flash. \nRight Click on the desktop and go to Properties-Settings-Advanced-Monitor- and change the Refresh Frequency.

It sounds like floaters.  If it is, then you have nothing to worry about.  Usually you'll notice them if you are looking at a white board or the sky.  Some people have lots, some people have a few, and some people never notice them.\n\nIf you're interested, floaters are caused from protein clumps in the jelly ("vitreous" in fancy talk) on the inside of your eye.  As you move your eyes, they slosh around and cast a shadow on your retina, which is what you can see.  If you hold your eyes really still, you'll notice they slow down and eventually disappear.\n\nAnother thing that is a possibility are "ocular migraines."  I would recommend that you get your eyes checked by your family eye doctor just to be on the safe side.

Your photoreptors and your visual cortex cells randomly fire, it is background noise a bit like you get with a CCD camera. Also you may notice that if you put pressure on your eyeball (not too much!) you will see a bright spot - so photoreceptors respond to more that just light.\n\nI get this too and my vision is fine.

you need to go to a doctor.  double vision could be a bad symptom of something.

you live with it. I had that too fairly recently. The light flashes at night were first pretty irritating, especially before I figured out what was happening, but by now they nearly disappeared. My eye doctor explained to me that the vitreous body is pulling at the retina causing exitation in the retina cells and hence light flashes, typically towards the corner of your vision. Once the separation is complete the light flashes stop. The problem is, that the pull can cause tears in the retina which has to be treated very rapidly so it doesn't get worse. \nTears in the retina are supposed to cause black spots in your vision and that's when you want to go contact your retina specialist immediately. Luckily I don't have personal experience with that so far. Though I think as long as it is treated quickly it is not going to be a big deal since somebody invented lasers to glue the retina back on. \nOnly thing which still bothers me are floaters, but that is also supposed to get better, though it is supposed to take more like a year than a month.

You could be having spasm of the muscles around the eye. You first need to diagnose the cause and treat it if necessary. If there is nothing, try botox

Maybe it is some kind of hallucination.. You may wish to see a psychologist about it. Certain illness might trigger it..

You better talk to your doctor, that's not normal. Lot's of things can cause it . It could be something as simple as needing glasses or it could be something a little more serious. \n\nGood luck to you:)

I think you need to go get your eyes checked,I get like that when I don't wear my glasses and I'm on the computer a lot.

See your eye doctor or go to the emergency room immediately!  Your eyes normally dilate together when exposed to dim lighting.  One eye dilating is abnormal and needs to be investigated.

Sometimes tis can be an indication of a migraine coming on.  I have only had this happen to me once but it was a spectrum of colors off to the side of my vision.  I called the doctor right away and that is what they told me.  I ended up getting my worst migraine ever!  When you have symptoms like this though,it is always best to see your physician.  If they feel follow up is necessary they will probably have you see a neurologist and possibly run an MRI or CAT scan to ensure there isn't an underlying cause for this happening to you.

Gaming can be very harsh on the eyes! The light from the screen causes a lot of damage to the eyes and it may end up being serious. To avoid more trouble try to limit your gaming time. I know that is hard to do, especially now that it is summer, but to save you vision, I'd calm it down a bit! Go play outside some more! I get Migraine headaches which are a lot like over exposure to iridescent light....you start seeing spots and you get really dizzy and light headed. Then a stomach ache follows along with a POUNDING headache. I lie down for awhile and drink a lot of juice and the spots usually fade away. I also take Tylenol or another form of medicine. I am not sure if this will help you or not, but it is worth a try. Good luck to you and your brother!

It is possible that you are having floaters which are actually tiny clumps of gel or cells inside the vitreous, the clear jelly-like fluid that fills the inside of your eye.\nFloaters may look like specks, strands, webs or other shapes. Actually, what you are seeing are the shadows of floaters cast on the retina, the light-sensitive part of the eye.\nHowever, if you are seeing flashes of light, there may be something more serious occurring such as retinal detachment. I would go see your eye doctor immediately.
