It’s unclear whether screens with warmer color tones help you get better sleep.Īs for other benefits, the Oasis works for both lefties and righties. Some studies have shown that blue light emitted from screens, including smartphones and some e-book readers, can act as a stimulant, disrupting your circadian rhythms and making it harder to sleep.

One quick aside: There’s a debate over whether the color tones of screens affect sleep. I set the device to adjust its light automatically, and at night, the warmer color tone felt easier on my eyes. The device has 25 LED lights - 12 white and 13 amber - to let you tweak the color tone from cool to warm manually or automatically on a timed schedule. The Oasis’s signature feature, the adjustable light, is a delight. Amazon’s cheaper Kindle Paperwhite, with a curved back that lacks the thick grip, is more pleasant to hold over long durations. But over several hours of reading, the wedge got tiresome to grip, and I found myself switching between hands. The Oasis is, over all, comfortable to hold.
