Screen Brightness Misconceptions: Why "Brighter is Not Always Better"

Jiangxi Wisevision Optronics Co., Ltd. is addressing a common misconception that higher screen peak brightness equates to a superior product. The company argues that "brighter is not always better," and excessive brightness can indeed be detrimental.

High brightness levels are primarily designed to enhance visibility in strong lighting conditions, such as outdoors on a sunny day. This feature allows users to clearly see content in environments where standard brightness would be insufficient. In this context, high brightness serves as a solution for visibility challenges in specific scenarios, rather than a benchmark for daily use.

However, using excessively bright screens in dim environments or at night can lead to problems. The eye's pupils naturally dilate in low light. When faced with an overly bright screen, a large amount of intense light enters the eyes, potentially causing visual fatigue, dryness, and discomfort as eye muscles work to compensate for the significant brightness difference.

Furthermore, at higher brightness settings, the total amount of blue light emitted by the screen increases. This high-energy, short-wavelength blue light may contribute to cumulative retinal damage and suppress melatonin secretion, negatively impacting sleep quality.

Wisevision emphasizes that optimal eye comfort is not achieved by pursuing extreme brightness, but by a screen's ability to intelligently adapt to its surroundings. The company recommends enabling the "Auto-Brightness" feature, which adjusts screen brightness in real-time based on ambient light. Additionally, utilizing features like "Night Shift" or "Eye Comfort Mode" at night reduces blue light exposure and enhances viewing comfort, while Dark Mode can further minimize screen light intensity in low-light situations.
