Why Is Alexa Flashing Blue Light?
- Randall Mullins
A cyan spotlight on a blue ring means that Alexa is listening. The light ring glimmers briefly when Alexa has heard and is processing your request. A briefly glimmering blue light might also mean the device is receiving a software update.

Amazon.com: Preguntas y respuestas de los clientes Mostrando 1-9 de 9 respuestas I had the same issue. I found that if you turn the sending device on and set for bluetooth pairing then turn speaker on it will keep flashing blue even after pairing. If I turn the speaker on first and then the sending device and let them pair the blue light will turn solid.

What does a flashing blue light mean?
What does a blinking or turned-off blue camera light mean? A blinking or turned off blue light means something is wrong with your camera. If the blue light is off, there’s no power going to the camera. Check the power source and, once power is restored, please contact your client support manager.
Why does Alexa flash blue at night?
Final Thoughts – With that, I hope I’ve conveyed why your Amazon Alexa is displaying blue lights, and as you can see, it is not a cause of worry. The blue light tells you that Alexa is processing your command or is starting up. I’ve also discussed other colors of the light ring and what they mean, like Yellow, Red, Orange, Green, Purple, and White.
What does flashing light mean?
Uses – Headlight flashing attracts attention, and so can be considered the visual equivalent of blowing the horn. Indeed, some car owner’s manuals identify headlight control on the steering column as the “optical horn”. Like the horn, it has many uses.
Headlight flashing can let other drivers know of one’s presence. Flashing can acknowledge the presence or actions of other drivers. Flashing can be a signal that the flashing driver is yielding the right of way, for example at an intersection controlled by stop signs. Flashing can warn other drivers of road dangers, such as crashed cars or police speed traps,
Flashing can be used to give thanks. For example, when one is warned of police activity, it is sometimes considered courteous to flash back. Flashing can inform drivers of problems with their car, such as headlamps left off after dark, burned out or misaligned lights, or misuse of high beam rather than low beam in traffic; or to berate a driver who poses a risk to traffic.
- Headlight flashing coupled with blowing the car’s horn can help clear deer from a driver’s path.
- Flashing can indicate the intention to overtake or pass another driver, or to signal a driver who has just overtaken that he or she can now return to the original lane.
- Flashing can request or insist that a leading driver speed up or change lanes to get out of the way of a faster following driver.
Headlight flashing may constitute aggressive driving, and can be used in an attempt to intimidate others into speeding or otherwise driving unsafely. Some drivers attempt to communicate “I will continue my current behavior!” when flashing their headlights.
For example, if such a driver flashes his or her headlights while slowing down, they intend to communicate to another driver who is waiting to merge in traffic: “Go on, I will let you merge!” On the other hand, if such a driver keeps his or her current speed and flashes headlights, they intend to communicate “Stay back, I am not slowing down!” Headlight flashing may also indicate protest or celebration of an event or political position.
Motorcycle headlamp modulators automatically oscillate the intensity of the headlamp in an effort to make the motorcycle more conspicuous to other drivers.
Does blue light mean blue light?
Natural Blue Light v. Artificial Blue Light – Blue light wavelengths are everywhere and surround us. In fact, they’re the reason the sky appears blue. These short blue wavelengths collide with air molecules, which causes the blue light to scatter and makes us process the sky as blue.
Does blinking mean anything?
Blinking more frequently can be annoying, but it’s rarely a sign of a serious issue. Some possible causes of more frequent blinking include: eye irritation, due to irritants in the air, dry eyes, a scratch on your cornea, inflammation of your eyelid or iris, having something in your eye, or other reasons.
What is the difference between a flashing light and a blinking light?
‘Blinking’ implies that raise time and fall time are of rhe same magnitude. ‘Flashing’ implies that the raise time is very short and of a magnitude smaller than the fall time.
Why is flashing lights a warning?
Flashing lights can induce seizures for people with epilepsy. Avoiding them reduces the chance of a medical emergency. Blind and visually impaired people use screen readers to interact with websites and apps. A screen reader is a type of assistive tech that converts things on screen to audio and/or braille.
- It’s important that things are understandable and interactive to screen readers.
- Eyboard accessibility is essential for people who do not use a computer mouse (which might be because they have unpredictable or very specific movement due to a motor disability).
- Many Blind and visually impaired people also use keyboard interactions in order to use their screen reader.
Error support is accessible to people with a diversity of disabilities. A cognitive disability might affect how a person perceives and understands things. A physical disability might lead to unpredictable movement. Other factors such as environment, stress, and multi-tasking may also lead to errors.
In order to be accessible, gestures and interactions must account for people with physical and motor disabilities, who might have unpredictable or very specific movement. Flashing lights can also cause pain or discomfort for people who are sensitive to light or be distracting to people with ADHD, Autism, or other cognitive disorders.
This includes sirens, strobe lights, and other visual flashing effects. This references WCAG criteria 2.3.1 Three Flashes or Below Threshold (Level A) and 2.3.2 Three Flashes (Level AAA). Level AAA compliance is considered more difficult to meet because it requires more resources to fulfill.
Do I want blue light on or off?
Blue Light and Your Eyes – Prevent Blindness Sunlight is made up of red, orange, yellow, green, blue, indigo and violet light. When combined, it becomes the white light we see. Each of these has a different energy and wavelength. Rays on the red end have longer wavelengths and less energy. The largest source of blue light is sunlight. In addition, there are many other sources:
Fluorescent light CFL (compact fluorescent light) bulbs LED light Flat screen LED televisions Computer monitors, smart phones, and tablet screens
Blue light exposure you receive from screens is small compared to the amount of exposure from the sun. And yet, there is concern over the long-term effects of screen exposure because of the close proximity of the screens and the length of time spent looking at them.
It boosts alertness, helps memory and cognitive function and elevates mood. It regulates circadian rhythm – the body’s natural wake and sleep cycle. Exposure to blue light during daytime hours helps maintain a healthful circadian rhythm. Too much exposure to blue light late at night (through smart phones, tablets, and computers) can disturb the wake and sleep cycle, leading to problems sleeping and daytime tiredness. Not enough exposure to sunlight in children could affect the growth and development of the eyes and vision. Early studies show a deficiency in blue light exposure could contribute to the recent increase in myopia/nearsightedness.
Related links: www.ncbi.nlm.nih.gov/pubmed/25535358 Almost all visible blue light passes through the cornea and lens and reaches the retina. This light may affect vision and could prematurely age the eyes. Early research shows that too much exposure to blue light could lead to: parts of the eye Digital eyestrain: Blue light from computer screens and digital devices can decrease contrast leading to, Fatigue, dry eyes, bad lighting, or how you sit in front of the computer can cause eyestrain. Symptoms of eyestrain include sore or irritated eyes and difficulty focusing.
Retina damage: suggest that continued exposure to blue light over time could lead to damaged retinal cells. This can cause vision problems like, If constant exposure to blue light from smart phones, tablets, and computer screens is an issue, there are a few ways to decrease exposure to blue light: Screen time: Try to decrease the amount of time spent in front of these screens and/or take frequent breaks to give your eyes a rest.
Filters : Screen filters are available for smart phones, tablets, and computer screens. They decrease the amount of blue light given off from these devices that could reach the retina in our eyes. Computer glasses : Computer glasses with yellow-tinted lenses that block blue light can help ease computer digital eye strain by increasing contrast.
Anti-reflective lenses : Anti-reflective lenses reduce glare and increase contrast and also block blue light from the sun and digital devices. Intraocular lens (IOL): After surgery, the cloudy lens will be replaced with an intraocular lens (IOL). The lens naturally protects the eye from almost all ultraviolet light and some blue light.
There are types of IOL that can protect the eye and retina from blue light. Talk to an eye care professional about options about ways to protect your family and your eyes from blue light. : Blue Light and Your Eyes – Prevent Blindness
What causes blue light?
What is Blue Light from Digital Devices? Is it harmful for eyes? Blue light, also know as high-energy visible (HEV) light, is a color in the visible light spectrum that can be seen by human eyes. These wavelengths of visible and non-visible light are measured in nanometers (nm), and, in general, the shorter the wavelength, the higher the energy. We are exposed to blue light on a near constant basis. The largest source of blue light is sunlight, but is also emitted by laptops and computer monitors, smartphones, tablets, TV, fluorescent and CFL bulbs. Our blue light exposure from digital devices are of particular concern because of the close proximity of the screens, length of time we use our devices, and the cumulative impact of using devices every day. There are some key differences between natural sources of blue light, like daylight, and artificial sources, such as the LEDs used in digital devices. Most of the light from the LEDs has wavelengths between 400 and 490 nanometers. Many LED screens peak in the 435-440 nm. This range is connected significant concern in medical research.1 Spectral distribution of typical daylight and LED light. Moderate amounts of blue light is essential for good health.2
Promotes alertness Boosts memory and cognitive function Elevates mood Regulates circadian rhythm
Eyes and Body Screen time has been on the rise for the last 20 years and is now exceeding 13 hours per day.1 According to the Vision Council, many people experience eye discomfort and vision problems when using digital devices for extended periods. As many as 65% of Americans report experiencing symptoms of digital eye strain, which may include symptoms of: 3
Eye strain Blurred vision Dry, irritated eyes Headaches
Sleep The use of digital devices at night may suppress the release of melatonin, the hormone responsible for making us feel drowsy. Too much blue light exposure from viewing screens at night may result in: 4
Impact to our circadian rhythms Trouble sleeping Waking up during the night Reduced alertness the next day
Long-Term There is evidence that the eye is susceptible to blue light exposure, and that over a period of time, cumulative exposure may increase the likelihood of vision problems. More research is needed to ascertain long-term impacts to the retina and any links to chronic vision problems.1 Children Children may be more vulnerable because their eyes don’t have the same blue light-filtering ability that adult eyes have. Holding a display twice as close quadruples the intensity. Children’s developing eyes allow more blue light to pass to the back of the eye. Screen time and blue light exposure have been raised as a growing public health concern. Doctors, educators, employers and parents agree that there are potential risks from overexposure. According to a recent survey, doctors believe the following are symptoms of excessive screen time and blue light exposure: 6
Sleep disruption (79%) Tired/ sore eyes (77%) Dry eyes (70%) Headaches (56%) Reduced productivity (46%) Reduced concentration (43%)
Data from Screen Time Report 2020 Blue light cannot be completely avoided, but there are ways to limit exposure. They include: 1. Eye Exam: Talk to an eye care professional about options about ways to protect your family and your eyes from blue light.2.
Screen Time: Try to decrease the amount of time spent in front of these screens.3. Screen Protectors: are available for smartphones, tablets, laptops and computer monitors.4. Built-In Technology: now have technology designed into the hardware, which helps reduce blue light emissions.5. Follow the 20-20-20 Rule : For every 20 minutes spent looking at a screen, a person should look at something 20 feet away for 20 seconds.6.
Anti-Reflective Lenses: Anti-reflective lenses reduce glare and increase contrast and may also help reduce blue light from the sun and digital devices.7. Use Device Software : Try setting your devices to night mode which adjusts the screen display to a warmer temperature, the downside is your screen will have a yellow or amber tint.8.

Why is blue light a problem?
How harmful is blue light? – Blue light exposure from screens is small compared to the amount of exposure from the sun. However, there is concern about long-term effects of screen exposure from digital devices. This is especially true when it comes to too much screen time and screens too close to the eyes.
According to the Vision Council, 80% of American adults use digital devices more than two hours per day. Nearly 67% use two or more devices at the same time. Fifty-nine percent have symptoms of digital eye strain. Since our eyes are not good at blocking blue light, nearly all visible blue light passes through the front of the eye (cornea and lens) and reaches the retina, the cells that convert light for the brain to process into images.
Constant exposure to blue light over time could damage retinal cells and cause vision problems such as age-related macular degeneration, It can also contribute to cataracts, eye cancer and growths on the clear covering over the white part of the eye.
- According to a vision study by the National Eye Institute, children are more at risk than adults because their eyes absorb more blue light from digital devices.
- People also tend to blink less when using digital devices, which contributes to dry eye and eye strain.
- Other common signs of eye strain include headaches, blurred vision, and neck and shoulder pain.
According to the Vision Council, 27% to 35% of Americans reported experiencing one of these symptoms after using digital devices.
