Protect Your Eyes Without Compromising Colour and Viewing Enjoyment.

ViewSonic's Blue Light Filter

At ViewSonic, our passion for visual display products and the need for improvements in eye care technology have driven us to introduce new blue light filter technology into our line of displays. This feature sets our popular LED-backlit displays at the head of the class when it comes to reducing blue light-related computer eyestrain.

Our Blue Light Filter technology can be adjusted to different viewing scenarios, lowering the amount of blue light output and protecting viewers from the possible side effects of blue light with little or no compromise of colour. In fact, as the blue line on the graph below shows, ViewSonic’s Blue Light Filter lets you reduce blue light by up to 87%.

With our line of displays featuring Blue Light Filter technology, you will be able to enjoy the following benefits:

Blue light is a natural colour of light that is found in sunlight. It is also a component that is necessary to correctly display colours on LED-backlit displays. On-screen, each colour your eye perceives is a combination of RGB (Red, Green and Blue) colours.

Blue light has a different effect on our eyes because blue-light wavelengths contain higher energy levels. On the visible spectrum, blue light is the closest to invisible UV light. According to the chart below, the blue light emitted by most LED-backlit displays has twice the amount of energy as green light that is displayed.

Research has shown that it is easier for our eyes to filter out green and red-spectrum light, as they carry less photon energy. However, the higher level of energy in blue light makes the eye unable to do this, which is why it has a more pronounced effect on viewers.

Most people are continuously exposed to bright and blue light sources even late into the night. However, according to a Harvard health publication, “Blue wavelengths – which are beneficial during daylight hours because they boost attention, reaction times and mood – seem to be the most disruptive at night.”

The higher levels of blue light emitted by LED backlit screens may lead to eye discomfort, dryness and even more serious conditions after prolonged daily usage. That’s why ViewSonic low blue light displays are better for the health of your eyes, and can help you to prevent the adverse effects that blue light may have on your eyes over time.

In fact, research has shown that prolonged exposure over time to all forms of blue light – from the sun, screens, displays and LED and fluorescent lamps – is harmful enough to cause eye strain, disrupt sleep patterns, and even cause eye damage such as cataracts and macular degeneration.

ViewSonic’s blue light filter is optimised to everything you view

ViewSonic’s Blue Light Filter technology optimises your display’s blue light level to match everyday viewing scenarios and accurately represent original colors. Now with expanded user-defined settings, ViewSonic displays will help to keep your eyes free of the effects of blue light while maintaining the best colour quality.

1. Greater adjustment flexibility with 100 filter levels

By providing a total of 100 filter levels, ViewSonic displays give users greater flexibility for a wider range of viewing scenarios. The blue light filter bar, seen below, can be adjusted from between 100 to 0 (level 0 is equivalent to a total 87% reduction) to effectively filter out blue light. As you decrease the level of blue light there is no visible change in the level of brightness on-screen, meaning the display backlight will stay bright.

2. RGB leveling maintains the correct colour balance


Image caption: ViewSonic Blue Light Filter maintains top colour performance and prevents colour distortion at lower colour temperatures by counter-balancing red and green RGB colours when lowering the display’s blue light output.

Blue light is progressively minimised from level 100 down to 0 along the blue light filter bar, while colour temperature remains optimised. To accomplish this we use a RGB 3-axis adjustment process to provide a smoother blue light filter transition and maintain the correct colour balance so that there is no colour distortion. Simply put, when we cut back the colour blue, we also simultaneously adjust the red and green tint on the RGB scale.
