What is Critical Flicker Fusion?

Critical Flicker Fusion is a simple app that can be used to determine the level of fatigue of the user. It is based on the fact that all humans have a certain level of visual sensitivity.

When the eyes are tired, the sensitivity of the retina drops, which results in a reduced ability to see small differences in brightness and color.

The most common symptoms of fatigue are drowsiness, lack of focus, and inability to concentrate.

How can I use this application?

The app has a standard mode and a manual mode.

The standard mode is based on the critical flicker fusion frequency.

The manual mode allows you to change the frequency of the flashes by using a seek bar.
