Amblyopia, also known as lazy eye, is one of the most common causes of visual impairment, affecting nearly 3 percent of the population. It occurs when the brain does not process input from one eye properly, causing the weaker eye to be suppressed by the stronger one. As a result, the affected eye does not receive clear images and cannot focus properly.
Traditional treatment often involves patching the stronger eye to force the weaker one to work harder. However, this method is usually effective only in children.
Lazy Eye Games take a different approach by sending information to both eyes, encouraging them to work together. This cooperation helps the amblyopic brain relearn proper image processing by increasing brain plasticity.
Studies show that patients who played the games with both eyes open saw significant improvement in the vision of their weaker eye after just two weeks.
Those who used patching also improved, but their progress increased substantially when they switched to dichoptic (both-eye) training.
Lazy Eye Games are designed for people with amblyopia—including adults.
Tip: In each game, you can adjust colors for specific elements (e.g., falling and landed blocks in Lazy Eye Blocks). The goal is for each eye to see only its assigned color. This teaches your brain to use both eyes together.

Lazy Eye Blocks
A Tetris-style game for amblyopia therapy. Falling blocks are visible to one eye, landed blocks to the other. Designed to encourage binocular cooperation and improve visual acuity.

Lazy Eye Breaker
A brick-breaker game for vision therapy. Paddle, ball, and bricks are distributed between the two eyes using dichoptic color separation. Great for improving eye coordination and reaction time.

Yes, this type of apps have been found to be an effective exercise even for adults because it is based on the team work of the eyes and force both eyes to work together.
The game works with any type of anaglyph 3D glasses. But if you want to make the color setup really easy then I suggest one of these glasses.
You can play with the left right colors as you wish but... e.g: If you have an amblyopic right eye then you adjust to be invisible for your right eye a moving game object and only see the not moving game object and left eye should see the moving game object and not the not moving game object ones. In this way the game is a bit easier than if chage up the colors. If you change up the two colors then the amblyopic eye should follow the moving game object what is a bit harder to do. So I suggest to start with the easier way then after 2-3 weeks change up the colors.
You should wear an anaglyph 3D glasses while you exercising (if you have prescription glasses then you should wear the 3D glasses over it).
If you have strabismus then the usage of the games can lead to diplopia. Don't play the games if you have uncorrected strabismus because uncorrected strabismus can lead to diplopia. Strabismus most of the time can be corrected by using prism glasses or undergoing eye muscle surgery. Use the games at your own risk and regularly consult with your optometrist, eye specialist and a vision therapist and if you have any bad experience or just not feel that it is good then stop applying the games.
You should play the game 40-60 minutes each day. You can split up that into 2 or 3 20 minutes sessions if you feel this more comfortable. The most important is to be able to concentrate in the timeframe while you exercising so if you tired just take a rest and continue later or sometimes you can skip a day to give your brain enough time to adapt the new inputs.
In general you can notice improvment just after two weeks of usage.
If you have problems to setup the colors after you have read the instructions then you probably own a low contrast 3D glasses I would suggest one of these. A higher contrast glasses (more darker) more easier to setup the colors to be invisible, with a low contrast glasses you should choose a very bright color to accomplish that. This is why a high contrast or darker glasses fits better to the game. If you were able to setup the colors just you were not able to make completely invisible the blocks but you can see when you play with one eye or both eyes then you are good with the settings and you can play the game it will be beneficial just always pay attention what see and concentrate to use both eyes together.
I recommend to learn more about the topic and the best start can be a great book Fixing My Gaze by Susan R. Barry. Don't be afraid it's very enjoyable because the author writes her own personal experience as well beside the scientific insights.
