Lazy Eye, also known as Amblyopia is a medical condition that causes the vision in one of the eyes to be reduced because the brain and the eye are not working together properly. Recent research has suggested that new techniques are much more effective then patching. Lazy Eye Therapy Blocks takes advantage of these new techniques to make Lazy Eye Therapy fun and effective.

You will need a pair of traditional red/cyan(blue) 3D glasses to use with this application. It isn't a 3D game, but the red and blue filters force the eyes to work together as only one eye can see the red falling blocks and one eye will see the blocks after they land and turn blue.

iCStraight applications allow treatment without patching. This is important as it works on the binocular performance of the two eyes requiring them to work together in a fun and entertaining way. Always check with your optometrist or ophthalmologist before discontinuing their recommendations.

***** This application requires the use of Red and Blue 3D Glasses *****
***** 3D glasses are inexpensive and widely available at eBay or other sources *****

Fantastic App


This app is fantastic! Finally an app for lazy eye that uses the latest, proven techniques. I tried a few of the other lazy eye therapy applications, but this application is intuitive, elegant and the gameplay is excellent. Also, this app doesn’t include any ads. For the therapy to be successful, you need to play the game with a pair of 3D glasses for 15 minutes a day (the 3D glasses are inexpensive and easily found on the internet). My son enjoys the game so much, he often plays it without the 3D glasses after his daily therapy session is over!

Thank you,

Seems to work

Great Music App! But...

This app serves its purpose of making both eyes work, however the spectrum of blues are definitely not dark enough, meaning I cannot select a blue that is dark enough for me to not see it with my left (red) eye. On the other hand, the darkest red is dark "enough", but for it to be black and completely invisible to the right (blue) eye, I need to adjust my phone's brightness to go darker. I would give a five star rating if this issue was fixed.

All red blocks are black

Utter fish

In the settings view I close my left eye and all red blocks are black but I can see degrees of blue, while wearing glasses with the red filter over left eye. I can see degrees of red and blue with right eye closed. How do I choose the blackest red block if they are all black?
