Computer Related Health Problems

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 a 90% 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. 

In addition to causing CVS, the computer is a 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 use a computer screen protector to protect your eyes.

What are computer screen protectors?

The computer screen protectors can reduce blue light, glare and adjust the screen brightness to protect our eyes from electronic screens. They can be physical devices or software.

Anti glare computer screen protector for eyes


The glare of reflection on the computer screen is the one cause of eye strain. The reflection on the computer screen will constantly distract your attention, forcing you to make extra efforts to concentrate and ultimately leading to eye strain.

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 most of the glare that is reflected from the screen to your eyes.

Advantages:  It can effectively reduce glare and Ultraviolet rays.


Disadvantages:  Installation is difficult, it is easy to leave annoying dust and bubbles in the installation process, and does not have the effect of filtering blue light.

Blue Light Filter Windows 7

Are you looking for a blue light filter for Windows 7?

Then you have come to the right place. Next, I will show you how to reduce blue light on Windows 7 in a simpler way.

Blue light filter for Windows 7

 

CareUEyes is a Windows 7 blue light filter, which helps prevent eye fatigue, relieve eye pain and vision problems. It filters blue light by adjusting the color temperature, so you can freely control the filter intensity of blue light. The lower the color temperature, the less blue light.

CareUEyes is similar to the Night light on Windows 10. You can use it as windows 7 Night light, but it is definitely better than the Night light.

It has eight preset modes, suitable for eight different usage scenarios. Appropriate color temperature is preset for each, but you can also adjust the color temperature according to your needs.

Three ways to filter blue light

1. Drag or click the color temperature slider on the interface. Drag to the left to decrease the color temperature(reduce the blue light), and to the right to increase the color temperature (increase the blue light).

2. Using hotkeys

3. Select the color temperature in the tray right-click menu

Lightweight and easy-to-use blue light filter

 

CareUEyes can easily help you achieve intelligent blue light filter adjustment. Some software uses overlay translucent windows to filter blue light, but CareUEyes directly controls the display’s RGB value, which ensures compatibility with other software. You can also set the CareUEyes blue light filter adjustment feature to be disabled when a special program is running (for example, while running photoshop, to restore real color).

Unlike other blue light filter software on windows 7, CareUEyes has higher performance. It only needs 5M of memory at runtime, and it does not consume too much CPU time. And the package of CareUEyes is only 2M. I believe this is your best choice.

Sunrise and sunset feature

Although blue light is harmful to the eyes, proper blue light irradiation is beneficial to people during the day. Blue light can keep people awake and have the energy to finish work or study. Therefore, if you are not a person with extremely sensitive eyes, you only need to filter a small part of the blue light during the day and restore the light of the computer screen to light similar to sunlight.

But at night, blue light becomes very harmful, you need to filter more blue light to prevent sleep from being disturbed by blue light. Excessive exposure to blue light at night will cause sleep problems. Because blue light inhibits the production of melatonin in the body. Melatonin is a hormone produced by the pineal gland. It helps your body know when to sleep and wake up. (External Factors that Influence Sleep)

According to people’s different needs for blue light day and night, CareUEyes provides sunrise and sunset feature. Compared with the sunrise and sunset, the color temperature and brightness after sunset are lower.

You only need to turn on the sunrise and sunset functions, CareUEyes will automatically help you adjust the color temperature and brightness at sunrise and sunset.

In addition to filtering blue light, more ways to protect your eyes


1. Follow the “20-20-20” principle

Every time you watch the screen for 20 minutes, raise your eyes and look at a place 20 feet away for at least 20 seconds.

However, many people often forget to take a break due to their busy schedules. CareUEyes can remind you to take a break regularly. It is not a simple timer, it is far more intelligent than you think.

CareUEyes can intelligently analyze the time you actually use the computer, and when you actually work on the computer for the predetermined time, it will remind you to take a break.

Yellow screen keep your eyes healthy

Have you noticed that more and more people like to set their computer screens to warmer colors, some even look like yellow screens? Does warm screen help eyes?

For example,  iPhone has Night Shift mode, which adjusts the screen to a warmer yellow by adjusting the color temperature of the screen.

Windows 10 also introduces the Night Light feature, which also adjusts the screen to a warmer yellow by adjusting the color temperature of the screen.

On Windows, there is some better eye protection software than Night Light, such as CareUEyes, which also has the feature of adjusting the color temperature.

Yellow screen is better for eyes

The yellow screen can effectively reduce the blue light emitted by the screen, relieve eye fatigue, and even help you fall asleep better at night.

If you haven’t heard the dangers of blue light, you may not like a yellow screen.

What is Blue light?

Blue light is light with relatively high energy with a wavelength between 400nm and 480nm. It has a shorter wavelength and is part of the visible spectrum.

Why is blue light bad?

blue light cause eyestarin

Blue light can penetrate the lens directly to our retina, causing the atrophy or even death of retinal pigment epithelial cells. The death of light-sensitive cells will result in decreased vision or even complete loss of vision. This damage is irreversible.

Blue light can also cause age-related macular degeneration, which can lead to permanent vision loss.

The lens of the human eye will absorb part of the blue light and gradually become cloudy to form cataracts, and most of the blue light will penetrate the lens, especially children’s lenses are clearer and cannot effectively resist the blue light, which is more likely to cause macular degeneration and cataracts.

Due to the short wavelength of blue light, the focus point does not fall on the center of the retina, but a little bit forward from the retina. To see clearly, the eyeballs will be in a state of tension for a long time, causing visual fatigue. You may experience symptoms such as eye fatigue, headache, blurred vision, dry eyes, neck and shoulder pain.

Blue light inhibits the production of melatonin in the body. Melatonin is a hormone produced by the pineal gland, which helps your body know when to sleep and wake up. Usually, at night, your body produces more melatonin. Once the sun starts to go down, the level of melatonin secretion starts to rise. This indicates that the body is ready to fall asleep. When the sun rises, the level of melatonin secretion starts to decrease and the body gradually began to wake up. Excessive exposure to blue light at night and insufficient melatonin secretion in the human body will keep people awake and unable to fall asleep, which causes the problem of insomnia.

 

Why can the yellow screen reduce the blue light emitted by the screen?

You need to know the concept of color temperature first. The concept of color temperature is based on an imaginary absolute black body, which emits different colors of light when heated to different temperatures, and its objects appear in different colors. Just like when an iron block is heated, the iron block first turns red, then yellow, and finally white. When heated to a certain temperature, the spectral component of the light emitted by the black body is called the color temperature at this temperature, and the unit of measurement is “K” (Kelvin).

If the light emitted by a light source has the same spectral components as the light emitted by a black body at a certain temperature, it is called a certain K color temperature.

For example, some common light sources and related parameters of color temperature: tungsten lamp 2700K; summer noon sun 5500K; cloudy 6500-7500K; candlelight 2000K and so on.

colour-temperature

 

The color temperature calibrated by this method is exactly the opposite of what the general public thinks of “warm” and “cold”. For example, people usually feel red, orange, and yellow are warmer, white and blue are colder, but in fact, red has the lowest color temperature, and then gradually increases are orange, yellow, white, blue, and blue is the highest color temperature.

A light source with a high color temperature appears blue and contains more blue light. A light source with a low color temperature appears reddish-yellow and contains less blue light.

The color temperature of the screen only indicates the spectral components of the light source, not the luminous intensity (the brightness of the screen indicates the luminous intensity of the screen).

Therefore, if we want to reduce the total amount of blue light emitted by the screen, one way is to reduce the blue light component in the spectrum, that is, lower the color temperature and adjust the screen to a yellowish tint. Another method is to reduce the luminous intensity of the screen, that is, to dim the brightness of the screen.

 

Are the color temperature and brightness as low as possible?

 

Although reducing the color temperature and brightness of the screen can help us reduce the harmful blue light, the color temperature and brightness of the screen are not as low as possible. Because the color temperature is too low, the screen will turn red, which will make the screen difficult to see. Too low screen brightness will also make the screen difficult to see, increasing eye fatigue. We need to keep the color temperature and brightness of the screen within an appropriate range.

What are the appropriate color temperature and brightness?

CareUEyes has the function of adjusting the color temperature and the screen brightness. It designs eight preset modes according to the most commonly used scenes in people’s daily life. The eight preset modes are health, games, movies, office, editing, reading, customization, and pause modes.  They have preset suitable color temperature and brightness so that you can quickly find the color temperature and brightness that suit you.

8 modes

 

The healthy mode has the lowest color temperature among all modes, and the screen looks slightly yellow. Your eyes may not adapt well at first, but soon you will find that such a screen looks softer, your eyes will no longer be tingling, dry, and tired.

Although blue light is harmful to the eyes, proper blue light irradiation is beneficial to people during the day. Blue light can keep people awake and have the energy to finish work or study. Therefore, if you are not a person with extremely sensitive eyes, you only need to filter a small part of the blue light during the day and restore the light of the computer screen to light similar to daylight.

But at night, blue light becomes very harmful, you need to filter more blue light to prevent sleep from being disturbed by blue light.

According to people’s different needs for blue light day and night, CareUEyes provides sunrise and sunset functions. Compared with the sunrise and sunset, the color temperature and brightness after sunset are lower.

You only need to turn on the sunrise and sunset function, CareUEyes will automatically help you change the color temperature and brightness at sunrise and sunset.

Prevent Eye Strain with the 20-20-20 Rule

Spending long periods looking at computer, phone, or tablet screens can strain the eyes. Using the 20-20-20 rule can help to prevent this problem.

The rule says that for every 20 minutes spent looking at a screen, a person should look at something 20 feet away for 20 seconds.

Following the rule is a great way to remember to take frequent breaks. This should reduce eye strain caused by looking at digital screens for too long.

In this article, we describe how to use the 20-20-20 rule effectively. We also discuss the research behind the rule and other tips for preventing eye strain.

How to use the 20-20-20 rule

The 20-20-20 rule was designed by Californian optometrist Jeffrey Anshel as an easy reminder to take breaks and prevent eye strain, according to the Optometry Times.

When following the rule, a person takes a 20-second break from looking at a screen every 20 minutes. During the break, the person focuses on an object 20 feet away, which relaxes the eye muscles.

Using CareUEyes makes it easy for you to follow the rules of 20-20-20

1. Turn on the Pomodoro Technique mode
2. Set the rest interval to 20 minutes
3. Set the short break time to 20 seconds (adjust the unit to seconds)
4. Set the long break time to 5 minutes
5. Set the long break cycles to 3 pomodoros (20*3=60 minutes)

More eye protection solutions for CareUEyes

In addition to the 20-20-20 rule, there are more ways to protect our eyes, such as blue light filtering:

    • Blue light filter.

      Blue light is a high-energy short wave. Continuous exposure to blue light can cause eye fatigue, dryness, pain, and aggravate myopia. Blue light can directly reach the retina of the eye through the passage to the cornea and lens. Long-term exposure to excessive blue light can cause irreversible retinal damage, such as age-related macular degeneration.

      Turning on the blue light filter feature can reduce the damage of blue light to the eyes.

      Other tips for preventing eye strain

      Like the 20-20-20 rule, the following methods can help to reduce or prevent eye strain:

      • Change computer settings. Making text twice as large as usual can reduce eye strain. Reading black text against a white background is easiest on the eyes.
      • Reduce screen glare. Protective anti-glare screens can be applied to computers and eyeglasses, to prevent eye problems. Also, flat screens tend to have less glare than curved ones.
      • Adjust the screen’s contrast. Change settings so that the screen is bright enough to read the text without straining. The right contrast may change, depending on the presence of sunlight.
      • Get regular eye checkups. Poor eyesight is a major cause of strain. Regularly attending checkups will ensure that a person has an updated prescription when needed.

      The strategies listed above require little time or financial commitment, but they can reduce eye strain related to using tablets, phones, and computers.

blue light cause eyestarin

 A screen dimmer for the night is necessary

Why do computer screens are harmful to our health, especially at night? One important reason is computer screens emit blue light. The brighter the screen, the more blue light is emitted. Blue light can cause eye fatigue and cause sleep troubles.  Research had shown that too much exposure to blue light at night can suppress melatonin production, disrupting our normal body clock and making our brains think it’s still daytime. A screen dimmer is very necessary for all people who use computers at night.

What is the feature of the  screen dimmer for the night

The screen dimmer for the night is a kind of software that can adjust screen brightness and filter blue light. It can help you avoid the damage of bright light to your eyes at night, and avoid the blue light at night from disturbing your normal sleep cycle.

What is Advanced Color API

The Advanced Color API is a term used by Windows developers. It uses GPU rendering and supports high dynamic range (HDR), wide color gamut (WCG), and high-precision (bit depth) visual content such as videos, games, and photos. Compared with the Color API, the Advanced Color API has better compatibility and performance.

CaeUEyes calls the Color API by default when adjusting the color temperature and brightness, but the Color API cannot work on some devices and must enable the Advanced Color API. Since it is impossible to accurately identify which devices need to enable the Advanced Color API, there may be a problem that CareUEyes does not work properly on some users’ computers because the Advanced color API features are not enabled.

In order to solve this problem, after the user newly installs CareUEyes, a pop-up will ask the user whether CareUEyes is working properly. If CareUEyes is not working properly, the Advanced Color API will be enabled.

However, there is a shortcoming when the Advanced Color API is enabled. It will cause the color of the picture to turn yellow when taking a screenshot, such as a screenshot below.

Advance color api

Therefore, it is recommended that for users who have enabled the advanced color API, it is best to set a hotkey to quickly disable and enable CareUEyes. You can use the hotkey to disable CareUEyes before taking the screenshot, and then use the hotkey to enable CareUEyes after the screenshot is completed, so that the color of the screenshot will not be distorted.

VibranceGUI

A little advantage over your enemies may be all you need to win the game. Cranking up your digital vibration will improve contrast and make it easier to spot enemies in the darker parts of the map.

What is the digital vibrance

Using Digital Vibrance (NVIDIA) or Saturation (AMD) in your graphic card driver can add an additional blast to your gaming experience due to more colourful images being output to your monitor. Digital Vibrance/Saturation might give you an advantage in games like Counter-Strike: Global Offensive, as it will ease spotting enemies in the game.

Using VibranceGUI

VibranceGUI is an application that automates NVIDIAs Digital Vibrance Control (“DVC”) by utilizing the NVIDIA Driver API. AMD support for automating Saturation has been added.

Using Digital Vibrance (NVIDIA) or Saturation (AMD) in your graphic card driver can add an additional blast to your gaming experience due to more colorful images being output to your monitor. It might even give you a slight edge when playing competitively in games like CS:GO.

The use of these settings comes with a huge downside though. Whenever switching out of a game back to Windows, the colors are still vibrant and don’t fit in the appearance of Windows. This happens because both settings will be applied system-wide. Luckily for you, this is where vibranceGUI comes into play.

Digital Vibrance/Saturation might give you an advantage in games like Counter-Strike: Global Offensive, as it will ease spotting enemies in the game. Many professional players use Digital Vibrance/Saturation nowadays. Some examples: GeT_RiGhT, f0rest, friberg, ScreaM. However, changing the setting manually in NVIDIAs or AMDs Control Panel after quitting CS:GO is annoying and that’s why I decided to create this tool

VibranceGUI is a small piece of software that allows us to set different levels of Vibrance for our games without messing with the Vibrance of Windows. It also sets the digital vibrance only for the programs we want (only games, not our desktop or browser) and we can set it to run onnce we boot our computer. To set up VibranceGUI for CSGO we have to open the program and click on the Add manually button. Then we just have to navigate to our Steam folder and find the csgo.exe file and select it.
