Why do I see red and blue dots in the dark?
965726
The color photoreceptors are cones, and they are part of day vision (or high light vision) only.  If you're seeing strange dots of color in low light, it could be an issue with your cones receiving false input or something like that, because normally they are not excited at all in low light.  You should probably visit an opthamalogist.  Incidentally, the cones are not sensitive to red, blue, and green, but blue-violet, blue-green, and yellow-green.

I see them too in the dark.. and I have 20/20 vision so I don't think there is anything wrong with you unless it becomes prominate.\n\n\nAsk your family doctor it couldn't hurt. \n\nI always thought it was for this reason...... your eyes are made up of rods and cones that pick up light and color\n\nI see this as being similar to pixles on a tv\n\nour eyes have pixles so to say, and in the dark for our eyes to create the image, you get light and dark pixilation... just my opinion...\n\nwhen it's really dark I see static, not just black..... I know exactly what your talking about\n\n\nyour the first person who has ever said this

Haven't you noticed that violet seems dim compared to blue? That's because only the blue cones are reporting it, but the green cones report a little when blue light hit them.

It could be a form of migraine starting.  The best thing would be to check with a doctor.  For some people, certain types of lighting brings on a migraine.

I get that sometimes too. I have hypoglycemia. I also take a medicine for depresseion called Welbutrin which I have taken for 4 years now. Also I have reached the ripe age of 41!  I think all these things combined is what causes my spots, blurryness and shadows. I was told by my eye doc that the floating spots that move are age spots that most people get with age (over 40). They are protien fillers that build up. The sugar imbalance cause the color spots. Eating more protien in my diet and less fats/carbs helps me.

well at night, your other senses arent as useful as your sight so. at night your eye sight doesnt get better but when it looks at movement it reacts with a more exagerrated appearance

these particles are not really present in the light that you see. They are actually the nerves in your eye which are illuminated by the intensity of light. the same effects are not noticed when you look directly at a low intensity light(eg. Tubelight, zero watt bulb etc.)

We see things in different colours because light (usually white) reflects off surfaces and reach our eyes with a different frequency, for some is absorbed. When NO light reach our eyes, it simply appears as black. You can see this as some form of 'natural default' (i coined this term myself). \n\nTo help your understanding, think of seeing a piece of paper filled with different patches of colours and holes, placed in front of vaccuum space. The black that you see will be the holes where no light get bounced off. \n\nHope this helps=)

Try checking your blood pressure it might be high.  The lights are cause dfron the pressure of you blood and it is incresed when you cough any lights in your eyes are cause for concern. Talk to your doctor

If it's lost all traces of red color, this means one or more of your phosphor guns is dead.  It's time to replace the monitor.  I'm unsure, but I don't think any repair shop will fix this for you...or even can.  Don't try to mess with it yourself.  It can be fatal even if it's unplugged.

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.

That is a result of the flash being so quick that the eyes remain wide open and the inside of the eyes (retina) with its rich blood vessels is illuminated by the light. That makes the devilish looking red spots. People with light colored eyes are more likely to get a lot of light inside the pupil of their eyes and show up with red eyes.\n\nShooting the photo in available light not flash, using a camera that has a preflash to get the pupils to contract, or not shooting the picture head-on will avoid it. If you get it then photo imaging software can easily remove it.

This is a permanent damage that has happened to you LCD screen. \n\nThe problem might be dead or lit pixels:\nOccasionally the individual transistors responsible for carrying current to a pixel either short out or remain open resulting in what is called a dead pixel. \n\nA "lit" pixel is one that appears as one of several randomly placed white, red, blue or green pixel elements on a dark background, or you may have a "missing" pixel which shows up as a black dot on a light colored background.\n\nThis can only be replaced by the manufacturer as usually this kind of problem is not repairable in India.\n\nIf your laptop is under waranty period your lucky!

that sounds like a problem with your computer screen. the colors change when the monitor is about to stop working

You are seeing the effect of pressure on the rods of your eye, which are fooled into thinking they see light. It should appear on the opposite side from which you press. It's called "phosphene".

Do you have floaters? Floaters will appear as little black specks in your vision. If you have those and are seeing the bright flashes of light then you really need to get to a doctor as soon as possible. Your retina could be detaching. This also can be caused by an ocular migraine. Look up floaters and ocular migraines on the internet and read more about the symptoms of each.

You reminded me of my childhood days. I used to ask my father the same Questions.\n\nClouds don't go any where during night. They are still there it only that there is not enough light for us to see them. Remember when you see moon light we see those clouds around or sometimes the moon hiding behind the clouds.
