Is high brightness or low brightness better for your eyes?

The optimal brightness for your eyes depends on the surrounding lighting conditions and the activity you're engaging in. Here are some guidelines:

General Tips for Screen Brightness:

1. Match Ambient Lighting:

Daytime/Well-lit Rooms: Higher screen brightness is usually better as it reduces the contrast between the screen and the environment, making it easier to see.
Nighttime/Dimly-lit Rooms: Lower screen brightness is preferable to reduce eye strain and prevent a harsh contrast with the dark surroundings.

2. Avoid Glare:

Excessive brightness can cause glare, leading to eye strain. Adjust the screen to minimize reflections and glare.

3. Comfortable Contrast:

Ensure the contrast between the text and background on the screen is comfortable. High contrast is typically easier to read but shouldn't be so high that it causes discomfort.

4. 20-20-20 Rule:

To reduce eye strain, follow the 20-20-20 rule: every 20 minutes, take a 20-second break and look at something 20 feet away.

Specific Scenarios:

Reading and Typing: Moderate brightness with good contrast between the text and background.
Gaming/Watching Videos: Adjust brightness to a comfortable level that avoids eye strain while still allowing you to see details clearly.
Working with Graphics: Higher brightness might be needed to distinguish fine details and colors accurately.

Blue Light Consideration:

Use Blue Light Filters: Blue light from screens can disrupt sleep patterns and contribute to eye strain. Use blue light filters or night mode features, especially in the evening.

Ultimately, the best brightness setting is one that allows you to comfortably see the screen without causing eye strain. Regular breaks and proper lighting in your environment are also crucial for eye health.
