Words go blurry after staring at a screen
You read fine for a while. Then the text starts to swim. The letters lose their crisp edge, and you have to blink hard or look away to get them back.
Close work asks a lot of your eyes. Tiny muscles inside each eye hold your focus in close. After a long stretch, that hold can slip, so focus lags when you look up.
Other things stack on top. Screens make you blink less, so the wet film on your eye dries and breaks up. Small type, glare, a screen held too close, or glasses that no longer match your eyes can all add to it.
When to see someone
See an eye doctor if the blur stays after you rest your eyes. Get same-day care for sudden blur in one eye, eye pain, or double vision. New flashes, floaters, a shadow in your sight, or a bad headache also need a doctor now.
Below is a list of remedies that people use for digital eye strain. Each one carries a grade. The grade tells you how much good research exists, not what will happen for you.
