With prolonged use of smartphones nowadays, it is much more common to experience eyestrain and fatigue. It seems that the cause of eye fatigue is due to the blue light emitted by most smartphone devices. Philips is hoping to combat it with the release of two new smartphones.

Philips recently unveiled the Sapphire S616 and the Sapphire Life V787. The two smartphones feature SoftBlue technology that reduces the amount of blue light emitted by 86 percent.

The Philips Sapphire S616 features a 5.5-inch IPS display with a 1080 x 1920 screen resolution and 401ppi pixel density. It is powered by an octa-core 1.3 GHz MediaTek MT6753 processor, the Mali T720 GPU and 2 GB of RAM. It has 16 GB of internal storage but can be expanded up to 128 GB via a microSD slot.

The smartphone is equipped with a 13 MP rear camera with an f/2.0 aperture. In front, there is a 5 MP camera with a wide-angle lens for selfies and video calls.
