Long shifts mean long hours in front of a screen. By the end of a twelve-hour stretch your eyes feel dry, your head aches, and text starts to blur. Digital eye strain is common among shift workers, and most of it responds to small, repeatable changes rather than a career change. Here is what causes it, what helps, and how to fit breaks inside a shift.
Staring at one close distance for hours keeps the focusing muscles working without rest. Blink rate also drops sharply when you concentrate, so the tear film protecting the eye surface thins out. Night shifts add another layer: you work when your body expects sleep, often under artificial light that is too bright or too dim, and both increase the load.
These symptoms are common and not automatically serious, but if they persist or get worse, get them checked.
Every twenty minutes, look at something about twenty feet (six metres) away for twenty seconds. The numbers matter less than the behaviour: breaking continuous screen focus and letting the focusing muscle relax.
Match screen brightness to the room. A screen far brighter than the room strains the eyes; one too dim makes you lean in and squint. On night shifts, try night mode or reduced blue light in the evening, and increase the font size instead of moving closer. Sit roughly 50 to 70 cm from the monitor with the top of the screen at or slightly below eye level. For lighting, use soft, spread-out light that does not reflect off the screen, and avoid lamps aimed at your eyes. If you want to see which hours hurt most, log shifts and hours in Shiftat-E so the pattern becomes visible.
Blinking is your first line of defence: concentration cuts blink rate dramatically, which is why the eye surface dries out. Remind yourself to blink fully, keep lubricating drops handy if a pharmacist recommends them, and keep air conditioning or fans from blowing at your face. See an eye doctor if pain or headaches continue, if your vision changes, or if symptoms are no better after a few weeks of adjusting habits. Seek urgent care for sudden vision loss or severe eye pain.
