    1

    Match screen brightness to the room

    ~15s
    If you squint at the screen, it is too dark. If the whites look painfully bright, it is too bright. Adjust until the screen looks the same brightness as a piece of white paper next to it.
    2

    Increase text size

    ~15s
    On Windows, right-click the desktop, pick Display Settings, and change the scale to 125% or 150%. On Mac, open System Settings, tap Displays, and pick Larger Text.
    3

    Turn on a blue-light filter

    ~15s
    On Windows, open Settings, then System, then Display, then Night Light. On Mac, open System Settings, then Displays, then Night Shift. Blue-light filters make the screen warmer — easier on eyes, especially in the evening.
    4

    Follow the 20-20-20 rule

    ~15s
    Every 20 minutes, look at something 20 feet away for 20 seconds. This lets your eye muscles relax. Set a reminder on your phone or watch if you forget.
    5

    Blink more often

    ~15s
    People blink about half as much when using screens, which dries out eyes. Keep artificial tears (saline eye drops) at your desk and use them when eyes feel dry — no prescription needed.

    Staring at a screen all day causes what doctors call digital eye strain — dry eyes, headaches, neck pain, and blurry vision. It is not permanent damage, but it makes you miserable.

    The fixes are small: brighter or dimmer screens to match the room, bigger text, blue-light filters, and the 20-20-20 rule (every 20 minutes, look 20 feet away for 20 seconds).
