TouchPal Night Filter for Android Devices Protects Eyes from Strain

All the devices these days make use of the LCD or LED screens whether they are desktop computers, notebook computers, tablets or the smartphones. But these screens are made up of very small light emitting diodes and they emit bluish light from them. This blue light has an effect on our mind – it mimics the daytime light coming from the Sun and keeps up awake. This can affect our natural body clock and sleep cycle. It can also put strain on our eyes if we use the smartphone in darker surroundings like at the night time.

An easy way to prevent all this is to use a night filter app in your smartphone which blocks the blue light and dims the light a little. Both of these effects work together to regulate our sleep-wake cycle and lower the strain on our eyes when using the smartphone or the tablet late at night.
