Tired eyes after a long day of screens — what works and what does not, when you are somewhere unfamiliar
Eye strain is mostly about distance and blinking, not about blue light glasses.
Start here
This is not complicated. It is inconvenient, which is why most people skip it.
It travels well. Hotels, spare rooms, other people’s sofas.
If you only do one thing from this page, do the first point below. It is first because it removes the most friction for the least effort.
What helps
Use a bigger font instead of leaning closer. Most people scale the font down to fit more on screen, then pay for it.
Warm, dim light in the evening is more comfortable than bright overhead light, regardless of what it does to your sleep.
You blink about a third as often when reading on a screen. Deliberately blinking a few times re-wets the surface.
What to do when it does not work
If your eyes feel gritty every day, get them tested. An uncorrected small prescription causes more strain than any screen.
Your eyes focus at one distance all day. Look at something far away for twenty seconds every twenty minutes — out of a window, not across the room.
Move the screen slightly further away and lower than eye level. Both reduce the work your eyes are doing.
Questions people ask
Do blue light glasses work?
Evidence is weak. They are not harmful, but the bigger wins are distance, blinking and a decent font size.
