Find the Light Fix That Fits Before You Buy Another Device

Choose the job in front of you: fix daytime and evening light, make screens less disruptive, verify flicker, match a goal to a modality, compare red or near-infrared devices, or estimate a session with a device you own.

  • Separate daytime and evening light; dim the display and room, schedule a warmer display spectrum, and shorten late exposure
  • Use PstLM and SVM when available, with modulation depth, waveform, dimming behavior, and test context
  • Choose a modality before a brand; compare red or near-infrared devices with measured data, and estimate dose only when you own the device and have measured irradiance
