If you tightly shut your eyes, what is the scientific name given to thelights you see flashing around?

If you shut your eyes really tightly, you put some pressure on your the cells in the retina.  These cells generally respond to light, but they also respond to pressure stimulation.  I think the name you're looking for is pressure phosphenes.

You are in a 10-foot room with a light in the center.  The photons leave the light, zoom to the wall in 5 nanoseconds, reflect off the wall, and (some of them) zoom into your eye 5 nanoseconds later,  where your brain perceives them about 300 millisconds later.\n\nYou turn off the light.  Generally, the light will cool and stop emitting photons within, say, 100 milliseconds.  But suppose it is a specially-constructed light, and it turns off in 10 picoseconds.  The last photons stream to the wall in 5 nanoseconds, reflect, and hit your eyes 5 nanoseconds later.   Some of the photons that miss your eye may reflect off the walls several times, but there is a 20 to 80% chance of their being absorbed by the paint on the wall each time they reflect.  The brightness in the room therefore decreases a factor of about 2 every 10 nanoseconds.  Within 100 nanoseconds, the number of photons in the room has decreased a factor of about 1000, and it becomes dark.

I can't sleep with any lights on either. But I don't have my room pitch black though. I like to sleep with nature's night light: the moon and stars!

Reflection of flashlight in the retina.\n\nFurther details:

I experience the same thing I was told by my therapist that the flashes are you subconscious searching for answers.  Are you going through a hard time because that would explain the flashes.

I read about this.  It happens in bright light because the optical and nasal nerves are so close together.  The brain is receiving all these signals from both that are so close together that it can sort of trick itself.

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.)

i do not know if u write the name right or not.\nanyway, it meams something that gives light

In the house I grew up in, lights used to come on in the middle of the nights all the time.  Just randomly all the lights in the living room would turn on then in the kitchen and all the bathrooms.  It was super freaky.

turn off all of the lights so that it is pitch dark in your house. Open the drapes. If it is lighter outside (full moon, street lights, etc) no one will be able to see in. Then take off all of your clothes and masturbate while looking outside. of course, you may want to go outside and look in just to make sure you can't see in. \nor... go buy a cucumber. ;-)

NO, because our eyes are normally closed when we sleep... Blinking occurs naturally and is triggered by our brain when it detects that the the eye needs moisture. Blinking at some point can trigger our tear glands to release liquid to help avoid dryness.\n\nThe phenomenon you see when a sleeping person seem to jitter his eyes when close is called R.E.M. or Rapid Eye Movement. This usually happens when a person is dreaming in his sleep.

Perhaps you are thinking of a general term, like phototropism ... meaning movement towards light. This is the phenomenon shown by sunflowers turning towards the sun. Some of the insectivorous plants that others mentioned, like Sarracenia, Nepenthes and Cephalotus don't actually move but catch their prey passively by luring them into their 'pitchers'. Fly Traps move, Drosera moves (v-e-r-y slowly) and Utricularia moves to trap the small critters in the little bladders. One plant that no-one has mentioned is the sensitive plant -- the second link shows it in action (response to a flame but touch will do it) and gives this movement the jaw-breaking name thigmonasty!!

Your pupils have dilated to allow extra light to come into your eyes to help see.  When the lights come on, your eyes are flooded with too much light because your pupils are still dilated.  Once your pupils adjust, your eyes are fine again.

These names come from the fact that some species as adults emit flashes of light to attract mates in order to reproduce, using special light-emitting organs in the abdomen. \n\nFireflies (family Lampyridae), also known as lightning bugs, are nocturnal, luminous beetles. \n\nThe enzyme luciferase acts on the substrate luciferin to stimulate light emission. This reaction is of scientific interest, and genes coding for these substances have been spliced into many different organisms.

There are also species of fireflies that mimic the flashing patterns of other species - when an unsuspecting lightning bug arrives expecting to mate - the mimic kills and devours it.\n\nThe actual mechanism for producing the bioluminescence is a chemical known as luciferin. This is a generic name for the light-emitting pigments found in several organisms. There are several specific types of luciferin. When a firefly wishes to flash, it activates nerves that introduce luciferin into specialized cells. There, in the presence of the enzyme luciferase, luciferin converts to oxyluciferin and cool light.

You might just have a little more light in one eye than the other or you could be dieing.
