Lazy Eye Reader can help on amblyopic and\or strabismic eyes. With proper settings the exercise is able to force the brain to use the inputs from both eyes simultaneously in this way teaches the brain to the proper image processing.
You should wear an anaglyph 3D glasses while you exercising (if you have prescription glasses then you should wear the 3D glasses over it).
There are some options you can adjust to be able to pick up a proper color or to make the exercise easier or harder.
On the top of the page you can find a textbox with a text what you can change to anything you want just to make the exercise not so too boring.
"Colored character count" is used to choose a range to how many characters should appear in one color next to the other colored characters. Count 5 can be a good for start, if you decrease the counter then you make the exercise a bit harder to do.
"Background color" You can choose a white or black background color. There are multiple types of 3D glasses and the colors and the contrasts are different so you can try both and choose what fit better to your 3D glasses
Font size slider can make the letters bigger or smaller, the default 100% font size should be good but if you find it hard to read then you can make the exercise a bit easier and increase the font size while you can read more comfortable.
"Left color" and "Right color" inputs can help you to adjust the proper color for each eye. These are color pickers so you should click on the "Left color" input (where you see the hexadecimal color code) and a color picker will pop-up where with the help of your mouse you can adjust the proper color. If you adjust the "Left color" then put up your 3D glasses and close your right eye and see only with the left and try to find a color (those characters what are changing automatically when you select a color) when the characters are not visible for the left eye. If you found that then close left eye and open right and ensure that you are still able to see the letters what was invisible for the left eye. If you was not able to found the proper color then try again or try to change the blackground color to white\black. After you successfully found the proper "Left color" then you should repeat the same process with the "Right color" where you should do the same thing just in that case you should find a color where the letter what belongs to the right color not visible for the right eye only the left.
After you was able to found both colors then you should start the exercise and try to read the colored text in the bottom of the page.
