In fact, studies have shown that prolonged exposure over time of blue light will cause digital eye strain, such as dry and irritated eyes. Although there are a large numbers of blue light filter apps (also known as Night Mode) that allow users to protect eyes, their efficiencies are still questioned. In this article, Allion argues that these apps can be useful tools for filtering out blue light. First, we will explain what blue light is. Then we will run tests after activating these apps.

“In 2010, in fall, at sunset, we came to the Blue Mosque in Istanbul. The sky was slightly dark. The evening sky was decorated with projection lamps. It’s so magnificent. When we saw a flock of birds flying around the domes of buildings, my friends and I took out our camera to capture the beautiful scene of the moment. However, no matter how we adjusted the camera or took pictures from different perspectives, the picture always seemed unnatural and was unable to simulate the image that human eyes perceived” (Fig. 1).

ULTRA HD Premium™ Certification Sets New Standard for Video Display Industry

03/01/201605/11/2017EN_Tech_Direct

As a next-generation digital video technology, Ultra-High-Definition (UHD) is gradually supplanting HD video across the consumer electronics (CE) landscape. In our homes, at work, and on the go, UHD is now available in a wide range of products, including televisions, computer monitors, video cameras, and mobile devices. Content producers, video service providers, hardware manufacturers, and retailers are all promoting the transition to UHD. For content producers and service providers, UHD presents an opportunity to bring cinematic quality experiences to smaller screens. For hardware manufacturers and retailers, UHD can attract new customers and thereby accelerate sales. A leading expert noted that, “There is considerable industry interest in the potential for (UHD) to speed up the next replacement cycle among CE shoppers”.[1] Now that UHD products have passed the early-adopter stage and reached mass-market price points, UHD products are primed for rapid growth in 2016 and beyond.
