Usually when you talk about eyes in photo editing, it's all about red-eye removal. This app goes so much further than that to make your eyes look any color in the rainbow. Eye Color Changer looks a little cartoony and bizarre at times, but that's probably the effect most people are going for.

This app's menu could use some major editing itself - it's quite the eyesore. It houses eight buttons, but only two of them actually go to features in the app you really want to use. The rest beg you to rate the app … Read more

Plus a serious summer … Read more

Last week, Apple announced that its App Store is approaching 50 billion app downloads. In celebration of the milestone, Apple is giving away a $10,000 App Store gift card to the lucky person who initiates the 50 billionth download.

As part of the celebration, Apple listed the top 25 apps -- both free and paid -- for iPhone and iPad. None of the apps listed is particularly surprising (especially to someone who studies the most-popular list every day), but one thing that did strike me is that a lot of the all-time best sellers still sit near the top … Read more

For the roughly three percent of the population that suffers from amblyopia, or "lazy eye," the best current treatment option -- covering the stronger eye to force the weaker one into better behavior -- works only some of the time in kids and has been totally ineffective in adults.

Now researchers out of McGill University in Montreal say that playing Tetris may ultimately treat the disorder in adults because the puzzle video game trains the eyes to work together as information is distributed across them in a complementary fashion.

"The key to improving vision for adults, who … Read more

Today, during the Demo Mobile conference in San Francisco, The Eye Tribe, maker of eye-tracking software for Android, announced that in June it will release a developers' kit for games and apps.

In its press release, The Eye Tribe claims to make the "world's first eye control software" for Android devices.

The software makes it possible to scroll down Web pages, play games, and unlock your home screen, using nothing but your eyes.

While devices like the Samsung Galaxy S4 are said to have eye-tracking software already, that handset's Smart Pause feature only recognizes whether your … Read more

Some users find that their computer background images are important. Satellite Eyes for Mac, which automatically changes the background image to a map of the user's current location, is an interesting personalization option for Mac.

Available as a freeware program, Satellite Eyes requires no payments to unlock its full functioning. The program downloaded and installed easily, with no interaction required by the user. Upon startup, the program prompts the user to enable the computer's location settings. It would have been a nice feature if the program took the user to that menu automatically, but it did not. Once … Read more

Some games are challenging. Others are grueling. Other still are a special blend of the two, pitting you against your own physical limitations but offering a clear reward when you successfully complete the puzzle. Such is the case with Challenge Your Eyes Free, a simple-to-play but tough-to-defeat game that forces you to find pinpoint differences between Chinese characters on 140 tiles.

The game is very simple in its layout. You start with access to only one puzzle. Every time you complete one, another unlocks. During each puzzle, you are shown a Chinese character. This character is hidden somewhere among 139 … Read more

If you've always wished you could watch 3D content on your mobile device, you're in luck. A team of Singapore-based researchers has developed a special film that turns the screens of mobile devices into 3D-capable displays.

The EyeFly 3D film, which looks just like a typical screen protector, actually consists of 500,000 miniaturized lens-like structures that measure about one-thousandth the width of a human hair. When applied to a mobile device, the filter works with dedicated iOS and Android apps to render stereoscopic 3D content for playback. Nanovue, a startup set up to bring the EyeFly 3D to market, is working on apps to convert existing 2D content to stereoscopic 3D.

There's one tradeoff: In our tests, the film made the iPhone 5's Retina Display look like it had a lowered resolution, as text and icons appeared to have jagged edges. Screen brightness remained the same. … Read more
