Why do people get so confused over the term "backllight"?
Case in point:

Because they're thick? As you say, the term does appear to be self-explanatory - a backlight is a light that's behind the screen.

Probably because all the tablets and smartphones these tech guys usually focus on are all backlit, it's the norm. "E-ink e-readers, hmmmm don't know as much about them but they'll just be the same, right?"
Edit: or as HarryT says, they're thick. That's probably it in a nutshell. |

I'll go with Harry's polite phrasing.
It's not as if there is any shortage of HDTVs with *side* lighting. So anybody writing about consumer electronics should know at least the difference between side-lighting and backlighting. |

The laziness prevents them from considering a two word term (e.g. "self illuminated") when there is a single word term available, even when the single word isn't accurate, and prevents them from searching from an appropriate single word term (e.g. "frontlit"). It's the verbal equivalent of when people need to pry something open and grab a screwdriver instead of an appropriate pry bar. |

The more interesting question is whether backlit vs. frontlit actually makes a difference. I understand that people claim a frontlit e-reader screen is easier on the eyes than a (backlit) LED. But, assuming both are set to the same level of brightness, I wonder whether that is true and, if so, what should cause this difference.

The other thing that comes to mind is that front-lit eink devices can drive their brightness lower than most (if not all) LCD devices. (Front-lit eink displays can go to zero lighting and still be readable.) The two most likely reasons for *some* people having issues with extended reading off LCD screens are the much higher absolute brightness and absolute contrast. It is possible to have too much of an otherwise good thing. |

They're not confused over the term(s), they just don't care what term they use. Especially when the average consumer isn't really all that interested in where the light's coming from. The distinction just isn't really all that important in the grand scheme of things (and those to whom the distinction is important will understand what's meant regardless of the terminology).

If it actually is this brightness-differential between screen and environments that causes eyestrain it should not matter whether an offending display is front- or back-lit. |

No one really cares about technicalities. Maybe backlight is simply a term to describe the light source of a display. Same way blackboards aren't black but green etc. |

Exactly - we still talk about the "limelight," even though lights using actual lime haven't been used for probably 150 years.

"Backlight" is the Kleenex of illumination terms.
*Edited to add: Kleenex is a widely available brand of facial tissue within the United States. The brand name has since become a generic term for any facial tissue, no matter who makes it. Last edited by LovesMacs; 10-04-2012 at 03:09 PM. Reason: Added explanation of Kleenex |

This has me worried in my wait for my Paperwhite. I'm afraid that the spillover from my K3's case light, while problematic in some ways, was actually a good thing, allowing my eyes to adjust to the overall lighting environment.

Normally, polarized lenses are a *great* thing; I use them outdoors myself. But I'm not sensitive to LCD eyestrain. Others, however? It is like CRT refresh-rate and fluorescent-light eyestrain; some people are more sensitive than others. And some people are more sensitive to polarized light eyestrain. Nothing is ever as simple as it appears at "first glance". |
