Blue Light Screen Exposure Melatonin Suppression

Estimate melatonin suppression duration from evening screen exposure based on device type, brightness, distance, exposure duration, and use of blue light filters

Each component has a specific meaning:

• Evening screen exposure based on device type — The evening screen exposure based on device type recorded for the scenario being assessed.
• Brightness — The brightness recorded for the scenario being assessed.
• Distance — The distance recorded for the scenario being assessed.
• Exposure duration — The exposure duration recorded for the scenario being assessed.
• Use of blue light filters — The use of blue light filters recorded for the scenario being assessed.

Note: Interpret the blue light melatonin impact result against the thresholds and context described above.

Enter the evening screen exposure based on device type, brightness, distance, exposure duration, use of blue light filters for the scenario you are assessing. Estimate melatonin suppression duration from evening screen exposure based on device type, brightness, distance, exposure duration, and use of blue light filters. Use the blue light melatonin impact result to inform your calculation.
