Quick answer: Then you probably don't need them much. Blue light glasses earn their keep with heavy screen use and evening screen time before bed. If you're rarely on screens and sleep fine, the upside is small, though they're still handy for the occasional late-night screen session.
When they're worth it even for light users
- You use screens in the evening, even occasionally, blocking blue light protects sleep
- The odd late work night, movie, or gaming session
- You have glare-sensitive eyes under bright lights
When you can skip them
If your screen time is minimal, mostly in daylight, and your sleep is solid, good habits (brightness, breaks, morning light) cover you, and glasses are a nice-to-have rather than a need.
The bottom line: Light screen use means low need, blue light glasses pay off most for heavy users and evening screen time. If you're barely on screens and sleeping well, they're optional, but still useful for the occasional late night.
