The harm of gradient color to the eyes

Quick answer：

Gradient colors, which transition smoothly between different hues, can sometimes cause eye strain or discomfort, especially in environments with high contrast or intense lighting. This is due to the visual fatigue caused by the brain's attempt to process these transitions. Prolonged exposure to such colors can potentially lead to eye strain, headaches, and even computer vision syndrome in sensitive individuals. It is advisable to use gradient colors cautiously and in moderation, especially in settings where visual fatigue is a concern.
