What’s on the Eye Strain poster?

5 numbered steps, with a full worked run-through. Digital eye strain is real, and is not caused by blue light. Apply 20-20-20 — Every 20 minutes, look at something 20 feet away for 20 seconds.; Blink deliberately — Blink rate drops by more than half at a screen, drying the eyes.; Set the distance — Arm's length, top of the screen at or just below eye level.; Match the brightness — The screen should roughly match the room, not out-glare it.; Reduce glare — Screen perpendicular to windows, never directly in front or behind.. Educational reference. Sudden vision change, pain or flashes need same-day medical attention, not a break.

Who is the Eye Strain poster for?

Eye Strain belongs to the Body & health section rather than to a school year, because health is not something one grade owns. Anyone learning prevention can pin it up — a beginner, a student mid-course, or someone revising years later.

When should you use the Eye Strain poster?

The problem is sustained close focus and reduced blinking, not the screen itself. A wall chart earns its place by being glanceable from where the work is happening, so Eye Strain belongs on the wall where that health work actually happens, within glancing distance, rather than filed away.

What other posters go with Eye Strain?

Air Quality, Antibiotics and Blood Pressure sit alongside Eye Strain in the Body & health section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.

Is the Eye Strain poster free to download and print?

Yes. Eye Strain downloads as a free PDF with no account, no email and no watermark, like everything else in the Body & health section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.

What size does the Eye Strain poster print at?

Eye Strain is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Eye Strain loses nothing.
