CareUEyes Lite

  Everyone has the right to protect the eyes, and we should not deprive it.

  On April 15th, 2019, we released CareUEyes Lite, a free basic version that is the best choice for anyone who likes free software.

  CareUEyes Lite has a basic brightness adjustment features, which has four brightness levels to choose from 20%-40%-60%-80%, all the operation interface is in the tray area.

CareUEyes Lite Tray Menu

  Unlike other brightness adjustment software, CareUEyes Lite does not use translucent windows to reduce brightness. It directly controls the gamma value of the display and is therefore not affected by the start menu and taskbar. It also does not affect the color of the mouse cursor and screenshots.

  In addition, click on the tray icon, you can easily restore or turn off the brightness adjustment features of CareUEyes Lite, very practical. And the installation package of CareUEyes Lite is only 600k, very small.

computer screen protector for eyes

  Computers have penetrated into every aspect of our lives. Whether in the workplace, at home or at school, the use of computers is now almost mandatory, and to a certain extent, for many of us, watching the screen is almost inevitable.

  Now apparent that prolonged use can lead to a series of computer vision-related problems, collectively known as computer vision syndrome (CVS) or digital eye fatigue, in fact, just a day spent on the computer for more than two hours, you will have 90% the chance of developing computer vision syndrome (CVS), most of us have experienced at least some of the symptoms of CVS. These symptoms include eyestrain, headaches, dry eyes, blurred vision, neck pain, computer vision syndrome is due to prolonged staring at the screen (computer, iPad, mobile phone, etc.) occur, these are some of the more common symptoms.

  In addition to causing CVS, the computer is notorious blue light emitter, Blu-ray also involves many other health problems,The excessive blue light on the screen can cause eye damage and may play a role in the development of age-related macular degeneration (AMD). It also suppresses sleep and can cause insomnia and disturb your circadian rhythm. If we use a mobile phone or computer before going to bed, it is more likely to cause insomnia.

  Therefore, protecting your eyes is vital whenever you use a computer, and you can take some steps to prevent the symptoms from getting too bad. There are 6 ways to protect your eyes from the screen, even if you have to stare at them all day long.

Anti glare computer screen protector for eyes

  The glare of reflection on the computer screen is the main cause of eye strain, and the reflection on the computer screen will constantly distract your attention, forcing you to make extra efforts to concentrate. This ultimately leads to eye strain, and you can use a high-end anti-glare computer screen to reduce the glare of your computer monitor. The anti-glare filter is available in two frame designs – flat or wrap. The frame you choose depends on your display style and personal preference, and with either of them, you can virtually eliminate all UV rays that are reflected from the screen to your eyes. There is another option – install eye protection software CareUEyes , which filters the glare of the display, is very convenient to use and is cheaper than the anti-glare screen protector.

Blue light filter computer screen protector for eyes

The screen protector can also be used to filter out the blue light emitted by the computer, which has a shorter wavelength than the other components of the visible spectrum and contains more energy. Excessive blue light can cause eye damage and can cause insomnia and disturb your circadian rhythm. You can filter blue light by installing a Blu-ray filter screen protector for your computer, but the Blu-ray filter screen can cause the display to be distorted, you may need time Adapting to this change, too much color distortion can exacerbate eye fatigue, and the eye care software CareUEyes can also filter blue light, CareUEyes is more powerful than the blue light filter screen and is more convenient to use.

Follow the “20-20-20” rule

20-20-20 rule: Every 20 minutes, look at something 20 feet away for 20 seconds. The 20/20/20 rule was popularized by Dr. Jeff Anshell, a specialist in “vision ergonomics.”, sometimes we forget With this rule, we can install the eye care software
CareUEyes , which will remind us to rest every 20 minutes.

20 20 20 rule

Adjust screen settings

  Downgrade the screen brightness, you want the brightness of the display to match the brightness of the surrounding work area, and if it looks like the light source in the room, it’s too bright. If it looks dull, it may be too dark, and the eye care software
CareUEyes can easily adjust the brightness to the appropriate value.

Don’t forget to blink

  Blinking helps to lubricate the eyes, otherwise, it can cause dry eye. When you stare at the screen for a long time, you will forget the blink of an eye, so we must consciously force ourselves to blink, which is helpful for the health of the eyes. Combined with the 20-20-20 rule.

blink eye

Timed rest

  When we are busy, we will forget to go to the bathroom, forget to drink water, forget to blink, forget to rest, but for the health of our eyes, we must rest regularly. If you can’t do this, then you have to use software to force yourself to rest. CareUEyes has a forced rest feature that reminds you to rest every 20 minutes.

About CareUEyes

  CareUEyes is an eye protection software that runs on windows. It has anti glare, blue light filtering, and timed reminder features. It is very convenient to use and is used by many companies and governments.

Conclusion to computer screen protectors for eyes

  We can reduce eye fatigue through physical devices, or relieve eye fatigue through habitual changes, but the most convenient way is to use eye care software
CareUEyes , because it is more convenient, cheaper and more effective, hope our article it is helpful for you.


Anti glare computer screen


  You can use a premium anti glare computer screen to reduce the glare of your computer monitor. The anti-glare filter is available in two frame designs – flat or wrap, and which frame you choose depends on your display style and personal preference, and with either, you can virtually eliminate all UV rays that are reflected from the screen into your eyes. Anti glare computer screen helps reduce eye strain.

anti glare screen


  Look for an anti glare computer screen with the following features:

  • Optical glass.

  High quality optical glass is superior to plastic.

  • Anti-reflective coating.

  A good glass filter has a multi-layer anti-reflective coating on one or both sides of the glass looking for a filter that provides up to 95% or 99% glare reduction.

  • Transmission.

  There are a variety of light transmissions in the anti glare computer screen, from about 30% transmission to 65% or higher.

  The intensity of ambient light in the work area helps determine the level of transmission that works best for you – the greater the glare, the lower the transmission you may need to reduce glare on the display.

  • Anti-static.

  Removing excess static electricity from the computer screen is important to help minimize dust accumulation on your computer screen, which can reduce the legibility of characters and look for anti glare computer screen with anti-static features.

  • Easy to clean the coating.

  Anti-reflective coatings show fingerprints and they can be difficult to remove. Look for an anti glare computer screen with easy-to-clean function, just clean the filter with water and a soft cloth.

  • ISO 9241-7 compliance.

This will ensure that the filter you purchased has passed the highest standard glare reduction test.

Disadvantages of anti glare computer screen:   

  •   Can’t filter blue light
  •   Can’t adjust display brightness
  •   Can’t change your viewing habits
  •   Different production standards may cause eye fatigue
  •   Will distract users

Other options

  Screen protectors can be used as anti-glare devices, but they can’t change your viewing habits. In addition to using anti glare computer screen, there are more ways to eliminate eye strain. We can use computer software to help us reduce eye strain.

how to use sunrise sunset feature

1.What is the sunrise sunset feature

The sunrise sunset feature means that when you turn on the sunrise sunset function of CareUEyes, when the time is sunrise, CareUEyes uses the color temperature and brightness under sunrise. When the time is sunset, CareUEyes uses the color temperature and brightness under sunset, all this is done automatically by CareUEyes.

2.Does the sunrise sunset feature useful for my health?

CareUEyes’ sunset and sunrise features are more suitable for those who work in front of the computer during the day and night. Usually, there is sunlight during the day. Our monitors are also adapted to the current environment. High color temperature and high brightness settings are used. At night, we use low color temperature, low brightness setting, which can reduce the blue light of the display (blue light will inhibit the secretion of melanin, but melanin is helpful for sleep), which helps us get better sleep at night and protect us eye. to use the sunrise sunset feature

(1) Ensure that the version of CareUEyes >=


(2) Make sure to enable the sunrise sunset feature

(3) Set the sunset sunrise time
(4) Set the color temperature and brightness of sunrise and sunset in the custom mode.


Note: When you set the color temperature and brightness of the sunset at sunrise, CareUEyes will automatically switch to the preview state, you can preview the effect in real time, but when you release the mouse, it will return to the color temperature and brightness of the sunrise state. Similarly, when you set the color temperature and brightness of the sunrise at sunset, CareUEyes will automatically switch to the preview state. When you release the mouse, it will return to the color temperature and brightness of the sunset state. In addition, the tray area will pop up a warning tips

The Science behind Blue Light

Visible light is a form of electromagnetic radiation. The wavelength of the light defines its

colour and also its associated energy. Longer wavelengths have low energy and are grouped as

warmer colours whereas shorter wavelengths have comparatively higher energy and are

grouped as cool colours. Blue light has a wavelength of around 400 – 470 nm and therefore has

more energy when compared to the warmer yellow – red colours of 600 – 700 nm. The colour

temperature that indicates the colour tones of light is generally measured in Kelvins (K). Colour

temperatures over 5000 K are called “cool colours” or bluish colours and the values between

2000 – 3000 K is called “warm colours” or yellowish colours.

Research shows that the penetration capability of the high energy beams into human tissues is

relatively high than their lower energy counterparts. This very concept is used in the X-ray

Photography as well. X rays that are high in energy than the blue light are so intense that they

pass through the soft human flesh easily. Bones and other hard tissues block most of the X rays.

A film captures the variations in these X rays as shadows of those tissues & bones. Medical

professionals study the internal structure of these objects with the help of these X ray


Why is Blue light harmful for eyes ?

Blue light has more energy can easily pass through the very sensitive cornea, the lens and

finally, almost all of it is reached to the retina of the eye. Colours like yellow, Red being less

intensive, will be blocked more by the lens of the eye before they reach the retina. This is why

warmer colours are generally pleasant for the eyes than the harsher cooler colours. This is true

even with the blue light emitted from laptop screens. A blue light filter for laptop screens like

CareUEyes can completely block this harmful blue light and render a pleasant warmer

yellowish light.


A continuous exposure of blue light from a laptop screen for extended periods of time leads to a

number of complications like dry eyes, headaches, eye twitches etc all of which are collectively

grouped under an umbrella term as Computer Vision Syndrome (CVS). As our eye is not able

to efficiently block most of the blue light, a long-term cumulative and constant exposure to this

high energy radiation will result in the damage and slow death of the cells of the retina. This

will accelerate the age-related macular degeneration (AMD) and ultimately results in a

permanent vision loss.

Blue light and Circadian rhythm

Human circadian rhythms have evolved to depend on the sun. We tend to be more active during

daytime when a lot of blue light is around us. During nights, our brain secretes a sleep

hormone Melatonin as a response to the absence of blue light. This hormone is very essential

for a good night’s sleep. High energy blue light also plays a major role in defining our mood,

activity and also sleep quality.

This very dependence of blue light for the regulation of circadian rhythm has made our bodies

evolve a special photoreceptor Melanopsin in the eye which is very sensitive to blue light. Light

as a factor now is very essential not only to our sleep but it acts like a synchronizer for many

other associated biological processes including temperature regulation as well. When the levels

of Melatonin rises in our body, as a response the body lowers its temperature and prepares for a

sleep phase. When Melanopsin receives blue light during the day, it triggers a response in the

brain to stop Melatonin secretion and our bodies come back from the sleep mode and become

active again. In this way, our entire biological clock runs on the basis of light.

Exposure to the artificial blue light especially from laptop screens during nights confuses the

body and distorts the circadian rhythm and thereby causes inability to fall asleep. This is the

very reason why it is difficult for people who work on the computer screen at night to fall

asleep. A constant exposure to blue light during nights keeps our brain at a higher activity level

for extended periods of time. This eventually leads to increased exhaustion, lack of focus,

anxiety and other complications which ends up in a lowered productivity. When the laptop

screen emits only warmer lights at night, our brain functions at a comfortable rate without any

disruption in the circadian rhythm and thereby decreasing sleep deprivation rate despite late

night working.

How can CareUEyes help us ?

Most computer monitor displays are designed to emit light that has blue colours around 6500K.

Laptop screens are primarily designed to emit a lot of blue light to create a natural daylight

effect on the screen. In order to protect our eyes from these harsher blue lights especially during

nights, a blue light filter for laptop screens in very much needed. Some hardware devices like

tinted screen filters can be used. Though they filter out blue light and other UV light from the

laptop screens, they also distort the text & images on the screen causing other complications

like “digital eye strain”. Aspects like different screen sizes may need different sized filters to

ensure a proper fit, need for a separate screen filter for every screen, complexity & bulkiness in

the usage and handling turns this option to become an expensive and complex affair in the end.


Another best way is to not use the laptop screens at all during nights. This isn’t a viable option

for working professionals, programmers etc who have to work late in the nights. An alternative

solution is very much required to suit the requirements of everyone.

CareUEyes is a lightweight, software version of the blue light filter for laptop screens. It

primarily runs on Windows OS. It runs in the background and does two things simultaneously

to constantly protect our eyes.

  1. It masks or “filters” the harsh blue light emitted from a laptop screen by shifting the

colour tones to the warmer parts of the spectrum.

  1. It lowers the brightness of the screen by changing the gamma value of the screen.

When these two things combined with the hardware screen brightness control of the laptop, the

user can get a pleasant viewing experience based on the contents of the screen and the

surrounding lighting.

Unlike the hardware screen filters, CareUEyes works on multiple monitors irrespective of

their sizes and configuration. One needn’t buy any hardware devices like tinted screen filters,

special tinted eyeglasses or anything else to protect their eyes from the harsher blue light

emitted from the screens. The user can now comfortably work for longer durations without

causing much strain to the eye and body.

Will CareUEyes damage my laptop ?

CareUEyes monitors the laptop screen constantly and shifts any blue light to its warmer

counterpart before it is emitted from the screen. It almost works at the graphics delivery level

by hooking to graphics rendering interfaces. Despite this constant monitoring, the amount of

CPU resources it consumes is almost negligible. Even memory consumption is also very little

compared to other alternative softwares. At most it consumes just under 5MB of working

memory of the system.

One need not be apprehensive about the working of CareUEyes. Though it works at the

graphics rendering level, it won’t in any way manipulate any of the systems / hardware settings

or change any configuration of the system. When the program is terminated, it cleanly exits and

restores all the natural and original colour schemes of the laptop screen.

Brightness feature of the program is equally important. The user can vary the slider between

20% to 100% brightness of the screen. The basic principle behind the change of brightness of

the screen is not at the hardware level but the program cleverly modifies the gamma value of

the screen in order to manipulate the resulting brightness and thus in no way affects the

hardware configuration of the monitor at all.

Unlike other methods that employ running a constant script to lower the brightness of the

screen, it just alters the final gamma output of the screen and the end result is a lower brightness

without any flickers/dots on the screen and a constant brightness spread across the monitor.

So CareUEyes will be well suited even for CRT & TFT monitors as well along with the modern

LCD / LED screen. It works equally well in programmatically controlling the gamma level of

the monitors irrespective of their inherent structural design or working.

All in all, CareUEyes filters the blue light and shifts the colour spectrum to warmer pleasant

yellow light, it reduces the brightness gamma of the screen and reduces eye strain so in the end,

during nights, as exposure to the blue light is reduced, it helps our brain to secrete Melatonin in

good quantities thereby helping us to sleep better. A uniform shift of colour tones and a uniform

brightness on the screen ensures a seamless experience to the end user. All of this is done by

consuming minimal computing resources ensuring no impact on the overall performance of the

system. The resource footprint of the software is also constantly maintained to be negligibly


More on the features of CareUEyes

CareUEyes has two sliders on the Display menu. One to change the colour temperature and the

other to programmatically change the brightness of the screen. The user can also assign hotkeys

to both these functions to simultaneously change them on the fly. This very feature separates

CareUEyes from other software solutions. It just sits in the tray while running in the

background, a single click on the tray icon activates the sliders screen. The user can now vary

both the colour temperature and the brightness on the fly with just a couple of more clicks.

It has 8 preset modes like Office, Reading, Editing etc that suits to various purposes. Editing

mode is very useful for programmers who wish to work late in the nights. The mode basically

inverts the colours on the screen thereby stripping out the bright colour tones completely. Other

modes give a quick combination of temperature and brightness values depending on the


Hotkey for colour temperature changes the value by 55K and the brightness hotkey changes the

brightness of the screen by 4% for every keystroke.

Just by changing the slider the user can reduce the colour tones to as low as 1000 K and can

increase to the natural 6500 K of the laptop screen. CareUEyes is capable of handling this wide

range of 1000K  6500K colour temperatures with ease.

A disable hotkey is also included to manually pause the CareUEyes working and restore the

original screen colours with the stroke of a hotkey. This is essentially useful for designers /

photographers/ artists who want accuracy of colours when they intend to use certain specialized

softwares. Rules can also be specified in the inbuilt rules manager to direct the working of

CareUEyes depending on the foreground software. When CareUEyes detects a whitelisted

software that is currently focussed / brought into the foreground / activated, it automatically

disables its working and the screen will have original colours till the software goes into the


The user still should have access to the hardware brightness control of the laptop screen to have

a complete and efficient control over the overall viewing experience depending on the ambient


It is recommended to change the colour temperature of the laptop screen to warmer values

when working late in the nights to prevent any distortions in the circadian rhythm / secretion

levels of Melatonin. If the user also sets a correct brightness level depending on the ambient

light, strain on the eye will be largely reduced thereby enabling the user to work for longer

durations comfortably.

The brightness value should be set such that the light from the screen matches with the ambient

/ indoor lighting. If the user works in a dark room with no ambient light, It is recommended to

set the brightness value to 20% and lower the laptop hardware brightness value to the

minimum. In other words, A laptop screen shouldn’t be the only source of light in the room.

Proper ambient light is equally important to reduce eye strain.


The very purpose of this article is to make one realize the harmful and cumulative effects of a

constant artificial blue light exposure particularly at nights from the laptop screens. In this era

of modernization, when computer screens have become an inseparable part of our life, an

efficient and a light weight blue light filter for laptop screens like CareUEyes, that can change

the colour temperature and the brightness, without compromising the systems resources, is a

great gift we give to our most precious eyes and to our overall wellbeing.
