Some people believe that dyslexia is related to vision. Below is a interesting video that features colored classes to help students with dyslexia. Decide for yourself.  There is also another video at http://www.kplctv.com/story/23064990/special-glasses-may-help-dyslexic-students.

 
There is no question that early diagnosis is the best thing for dyslexia.  But testing is expensive and people are not even aware of what really dyslexia is.  I came across a very interesting site/company that does on-line testing for dyslexia. 
It called lexercise at http://www.lexercise.com.  I have not don the actual testing, but it offers a free simple screening that takes 10 or so minutes.   They also offer some reading support through their technology.

Personally, I think the value of understanding if you are dyslexic is so valuable.  Many tests can cost up to $5000.  this offers a free test and full evaluation for about $500.  It's worth looking at. 
 
With dyslexia occurring in up to 20% around the world, people are starting to realize the mass audience.  A team in Indonesia is working on a new game to help those with Dylslexia using the x-box platform to help with balance.   
According to the Jakarta Post (http://www.thejakartapost.com/news/2013/02/05/ugm-students-create-form-game-therapy-dyslexia.html)

A group of six students from Gadjah Mada University (UGM) in Yogyakarta calling themselves the LexiPal team created a form of game therapy to help people with dyslexia.

Developed as a dyslexia therapy application based on the Microsoft X-Box Kinect platform, the game is designed to help students with dyslexia to balance functions between their right and left brains, thus helping them to cope with difficulties in understanding symbols and letters.

 
For those who have a really hard time reading, but are great with listening, there are some interesting tools.  Prizmo is one the coolest tools around and actually takes snapshot of whatever you want and then it will read the text aloud to you.  So if you are at the grocery store, for example, and you can't read the ingredients, you can take a snapshot of it and it will read the ingredients.  Very cool stuff.
 
Dragon speech recognition is another great tool to help those with Dyslexia.  According to Nuance, the maker of Dragon. "Students with certain learning disabilities, especially those with language-based learning disabilities like dyslexia and working memory issues, use Dragon to help them with writing by taking the focus off the mechanics of composition—spelling, sentence structure, etc.—so it’s easier to transfer ideas into written words."

It has been shown to improve core reading and writing skills for students of all abilities, including those with physical or language-based learning disabilities as well as English Language Learners. Dragon lets students dictate papers and assignments three times faster than typing — with up to 99% accuracy. It also lets them control their computer desktop and applications by voice to get more done faster — whether they’re sending email, taking notes, doing research on the Web, or creating a presentation. 
 
The LiveScribe Pen is another incredible invention to help students.  It's pretty simple really.  A students uses the pen to write notes, and while they are writing, the pen records the lecture from the teacher.  When the student is reveiwing their notes and wants to hear what the teacher was saying at that point in their notes, they simply touch the pen to their notes and listen to the recording.  Simple and amazing.
 
I don't know how many times I have misspelled things in important emails, memos or paper.  Like most other people, I use Microsoft word which has been great for checking my spelling, but the grammar check has never been very good.  So I simply struggled with it.  Recently I have come across another Microsoft product called Ghotit that looks fantastic.  It is exactly what a dyslexic needs - beyond spell check. 

Check it out.

Another great tool is the Intel Reader whihc actually takes a picture of text and then reads it.  Very incredible stuff developed by and for a dyslexic himself names Ben Foss.

According to Ben, "That led me to invent the Intel Reader. For me it is a ramp into a book. Independent research suggests that kids with dyslexia or other specific learning disabilities  can improve their reading comprehension test scores by up to 23% when using the Intel Reader. These days GE and Intel are selling the product through a joint company called Care Innovations."
