Constant exposure to screens has turned blue light into a household enemy. To combat it, there are three fronts: glasses with physical filters, software adjustments, and specialized monitors. Each option offers a different balance between effectiveness, cost, and comfort, with software being the simplest entry point for any user without spending a euro.
Software adjustments: the filter you carry inside the system 🌙
Tools like f.lux, Night Shift, or Windows' reading mode modify the panel's color temperature by reducing blue emission. They work on any monitor, even the most basic ones, and allow you to schedule automatic timings. Their accuracy depends on the monitor's color profile; on poorly calibrated screens, the yellowish tint can be excessive. They do not alter the hardware, so blue light remains physically present, even though our perception changes. They are ideal for nighttime use and long work sessions.
Orange glasses: the look your retina didn't ask for but needs 🕶️
Blue filter glasses turn you into a low-cost Blade Runner character. They work, yes, but the price is aesthetic: everything takes on an orange tint that makes your monitor look like a perpetual sunset. If you work with graphic design, forget about seeing real colors. However, when you put them on at eleven at night, your brain understands it's time to sleep, even if you just want to watch one more episode of your favorite series.
