If you are one of the millions of people who use a smartphone or a tablet, then you are at risk of suffering from eyestrain, a condition that makes it difficult to look at a screen for more than a few minutes without having to take a break. The problem is that, in order to protect your eyes from harmful blue light, you have to either constantly change the screen brightness or use a blue light filter.

In fact, there are many people who have to change their screen brightness all day long, while others are forced to use a blue light filter, which can cause them eye strain and many other problems. In order to avoid all of this, we have developed an app that will allow you to use a blue light filter without affecting the brightness of the screen.

The app that we have developed is called "JBlueCut". You can use it to filter the light that comes from the screen of your smartphone or tablet. You will not need to change the brightness of the screen, and you will not have to use a blue light filter.

The app will allow you to filter the light that comes from the screen of your smartphone or tablet.
