This extraordinary occurrence is called phosphene, and it’s believed to appear because of light inside our eyes. This light is naturally produced, and our retina responds to it, and we see color.Jun 6, 2022

Is it normal to see colors with eyes Closed?
Why do we see different colours when we close our eyes? — Anais, aged 7 Hi Anais, thanks for your great question! The first thing to say is that seeing colours when we close our eyes is totally normal. It doesn’t mean there’s a problem with your eyes (unless what you see changes drastically, but we’ll talk about that later). There are a few different situations that can cause you to see colours with your eyes closed.
The first one is if you shut your eyes in the daytime, in a bright room or outside. Some light does go through your closed eyelids. So you might see a dark reddish colour because the lids have lots of blood vessels in them and this is the light taking on the colour of the blood it passes through.
Why does pressing on your eyes make you see colors?
Why do we see stars when we rub our eyes? Asked by: Emma Smith, Peterhead These shapes and colours, called ‘phosphenes’, were reported as long ago as the time of the ancient Greeks. Rubbing your eyes increases the pressure within the eyeball and this pressure activates ganglion cells in the retina in the same way as light does. Your brain doesn’t know the difference and so interprets the activation as though you were seeing light from the world outside.
Most common phosphenes are diffuse blobs of different colours that move with the rubbing. Then there are scintillating and rapidly moving grid-like patterns which probably reflect the organisation of cells higher up in the visual system. These patterns are reminiscent of psychedelic paintings because the major hallucinogens also affect the visual system.
Why do we see black when we close our eyes?
Light comes from a light source The light then hits an object The light then bounces off the object into your eye Your eye sends a signal to your brain. Your brain then figures out what you’re seeing So in order for us to see, you need light getting into your eye (step 3). If you’re in a dark room you have no light source, so no sight (no step 1).
If you shut your eyes, you’re stopping light from getting into your eye (no step 3). When there’s no light getting to your eye, the eye tells this to your brain. So your brain just sees black (the absence of light).
Why do I see flashing lights when I close my eyes to sleep?
Posterior vitreous detachment is more common in patients who: Are short sightedHave undergone cataract surgeryHave had YAG laser following cataract surgeryHave had inflammation inside the eyeAre floaters serious? In most cases floaters interfere with vision only slightly. While annoying, they are usually harmless and come and go over the years. In some cases, floaters can interfere severely with vision. Floaters are sometimes caused by bleeding or inflammation in the eye. What causes flashing lights?
As the vitreous shrinks and comes away from the back of the eye, it can pull on the retina causing some of the retinal cells to fire off. You may see what appears to be flashing lights or lightening streaks. They are usually seen at night or in low light conditions. They may last for a few seconds or several minutes. They can occur off and on for several weeks or months.
What do most people see when they close their eyes?
Closed-eye hallucinations are patterns, snow, shapes, and colors you may witness when you shut your eyes. In most cases, these are harmless and aren’t a cause for concern. Some cases are related to medical conditions that require treatment. Talk with a doctor if closed-eye hallucinations are accompanied by other unexplained symptoms, or if you’re experiencing significant cognitive, vision, or mood changes.
What do phosphenes look like?
Symptoms The most common symptom when experiencing phosphenes is seeing small specks, squiggles or stars that move across your vision. While these types of eye floaters may feel as if something is on your eye or very close to it, the source is actually from inside the eye. Other common symptoms of photopsia or seeing phosphenes include: Floating shapes or dots in the eyes that move along with it. Shimmering, twinkling or glittering lights. Snow, static or fuzz in the visual field.
Zigzag lights that seem to flicker or strobe. Bright, vibrant colors. Treatment Seeing phosphenes is actually not a condition itself, but a symptom of an underlying problem (or an external factor, such as pressure from eye-rubbing). Treatment will be determined based on the preexisting condition.
Do your eyes roll back when you sleep?
Do Your Eyes Roll Back When You Sleep? When you start to fall asleep, your eyes may slowly roll back and outward. This movement is known as Bell’s phenomenon. Once in a deeper sleep, eye movements stop for a while until entering REM (rapid eye movement) sleep later in your sleep cycle. Do Your Eyes Twitch While You Sleep? An eyelid twitch is an involuntary, uncontrollable spasm of the eyelid.
This movement typically lasts a few minutes throughout the day and often disappears while you’re asleep.Potential causes of eye twitching include:
What does it mean when you see purple when you close your eyes?
What do phosphenes look like? People often describe phosphenes in terms of light even though there’s no light source. Some people say they’re glittery sparkles. Other people describe them as being like stars. Still, others see geometric shapes. What are the most common causes of phosphenes? Many things can cause you to see phosphenes. Sometimes you can see them spontaneously. Possible causes of phosphenes range from rubbing your eyes to neurological diseases or ocular (eye) conditions.
Phosphenes from a blow to the head You may have heard the expression “seeing stars.” If you hit your head or fall, you may see stars — bright flashes of light even when your eyes are closed. This reaction is similar to what you see when you rub your eyes and see light. Pressure on the eyeball can stimulate the retinal photoreceptor cells, causing the light you see.
