IT workers who face computers every day must be nearsighted, and the biggest trouble is that wearing glasses to watch the screen is really easy to fatigue. And this special i-Free is the gospel of myopia.

As an IT person who has been working on computers for a long time, maybe everyone is myopic, and will also find that looking at the screen every day, in fact, most of the fatigue comes from the eyes, which I think is a problem of the eyes. Ryan Choi, a Korean designer, discovered this and then thought about designing this screen saver i-Free.

This i-Free screen saver has the common functions of radiation prevention and brightness adjustment, as well as a specially designed small screen. This small screen is on the top of i-Free. You can measure the degree of your eyes watching the screen through induction, or you can adjust it to a comfortable normal degree through touch control, that is, adjust the function of glasses to i-Free.

I-Free uses clamps to fit the screen. Maybe the only problem is that there will be some problems when the notebook cover is closed. But such a small problem is not as comfortable as watching the screen with naked eyes.

Although the most fundamental solution to eye fatigue is to reduce the use time, but we need to work with computers, rest and brush microblog everything depends on the screen. The appearance of i-Free has saved a little, but it is still the king's way to have regular rest.
