Night mode vs blue light glasses: do you need both?
Night mode warms the colour of one screen. Blue light glasses filter everything you look at: the phone, the television, the laptop and the lights in the room. You can use both. A warmer screen setting can make the display more comfortable, but it does not replace the measured filtration of a lens.

What does night mode do?
Night mode shifts a display towards warmer colours, usually on a schedule. It is called Night Shift on Apple devices and Night Light on Windows and many Android phones. How much it changes depends on the device and how warm you set it. It changes that screen and nothing else.
What do blue light glasses do that night mode cannot?
They sit between your eyes and every light source, so one pair covers the television, a second screen and the room lighting. A lens can also carry a stated figure. SleepSpec’s deep-amber sleep glasses block 98% of blue-green light across 400–520 nm.
Clear blue-light glasses are a different product, made for daytime screen comfort: see amber, red and clear lenses compared.

Are blue light glasses better than night mode?
For most evenings, they cover more. Night mode is a good start: it is free and already on your device. It changes one screen, though, and an evening usually has more light than that. One pair of glasses covers the television, the second screen and bright indoor lighting together.
Should I use both?
Yes, if you like. Keep night mode on and wear the glasses for the 1–2 hours before bed, then take them off at lights-out. Blue-rich evening light can suppress melatonin and push the body clock, and sleep, later. Better sleep is not guaranteed, and individual results vary. Never wear the glasses while driving.
