1, Technical principles and light characteristics


2, The impact on the eyes

Blue light problem: Blue light is the shortest wavelength and highest energy part of visible light. Prolonged exposure to high-intensity blue light can cause damage to the retina, leading to problems such as visual fatigue and dryness. Both LED and LCD screens emit a certain amount of blue light. However, modern display technology has reduced the harm of blue light through software adjustments, hardware filtering, and other methods. For example, many monitors and smartphones are equipped with blue light filtering mode, which users can turn on when needed to reduce the impact of blue light on their eyes.

3, How to choose a display screen that is more eye friendly


Pay attention to eye hygiene: Follow the 20-20-20 rule (i.e. take a 20 second break every 20 minutes to look 20 feet away) to relieve eye fatigue.
Choose a high-quality display screen: When purchasing, pay attention to the product's display performance, eye protection features, and user reviews to choose a display screen that is more eye friendly.
