Twilight|健康線上App不用買-HotApp4Game

Are you having troubles to fall asleep? Are your kids hyperactive when playing with the tablet before bed time?

Are you using your smart phone or tablet in the late evening? Twilight may be a solution for you!

Recent research suggests that exposure to blue light before sleep may distort your natural (circadian) rhythm and cause inability to fall asleep.

The cause is the photoreceptor in your eyes, called Melanopsin. This receptor is sensitive to a narrow band of blue light in the 460-480nm range

which may suppress Melatonin production - a hormone responsible for your healthy sleep-wake cycles.

Twilight is an Android app that automatically adjusts your device's brightness (or really, color temperature) over the course of the day,

reducing the harsh whites and blues as the day progresses. We've talked about how to avoid eyestrain at the computer,

but when you're not staring at a computer screen, you're probably looking at your phone or tablet, and Twitlight can help.

In experimental scientific studies it has been shown an average person reading on a tablet or smart phone for a couple of hours

before bed time may find their sleep delayed by about an hour.

It filters the blue spectrum on your phone or tablet after sunset and protects your eyes with a soft and pleasant red filter.

The filter intensity is smoothly adjusted to the sun cycle based on your local sunset and sunrise times.

Twilight protects your eyes form damage it adopts the time of the day and automatically controls the light of your Android smartphone and tablets.

1) Bed reading: Twilight is more pleasant on the eyes for night reading. Especially as it is able to lower the screen backlight far below the ability of the backligt controls on your screen

2) AMOLED screens: We have tested Twilight on an AMOLED screen for 2.5 years without any sign of depletion or over-burning.

If properly configured Twilight causes less light emission (by enabling dimming) with more equal light distribution (dark areas of the screen such as the status bar get tinted).

This may in fact increase your AMOLED screen life time.
