Amazon's newest Kindle Oasis makes it easier to read at night

Amazon launched a new version of its cheapest Kindle earlier this year, but people with a little more money to spend just got some good news.

The new Kindle Oasis became available for pre-order on Wednesday, starting at a whopping $250. However, for nighttime readers, that price point could theoretically be justified. The big new feature this time around is a warmth slider that will let you add an orange tint to the screen for less eye strain while reading under cover of darkness.

Amazon released a handy image showing exactly how that works and what it looks like.

The basic, $90 Kindle and the $130 Paperwhite don't have this feature or the other features endemic to the Oasis. It's got a 7-inch display with a high resolution to make virtual books look sharp as can be.

Low resolution was one of the reasons we didn't love the newest version of the cheap Kindle when it launched in April.

Still, $250 (which goes up to $280 if you want more storage space) is a lot for an e-reader. You could get the default iPad for less than $100 more and it would be able to do a lot more. Obviously, if you buy a tablet or another e-reader used, the price goes down significantly.

Regardless, the new Kindle Oasis is there if you want it. If eye strain is a big barrier between you and e-readers, it could be worth a shot. Deliveries start on July 24.
