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. 
 
There are some good resources for dyslexia, but not enough.  One of the best I have found is called DyslexiaEd.com which is full of great videos from experts around the world on dyslexia.  There are so many, but one of the key points of the videos is this those with dyslexia have a hard time reading because they were not born to read - they were born without that skill potential well developed.

The man who started the network has written a great book called The Power of Dyslexic Thinking.

Check it out.

 
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.
 
A lot of people wonder what is like to have dyslexia .  The problem is, it's different for everyone.  It usually impacts reading, writing and spelling - but it's not that simple.  Below is interesting video that illustrates, pretty well, what it may feel like to have dyslexia.  You can see that things move around a lot - a tough thing when you trying to focus.
 
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.
 
Henry Winkler, the actor, is one of the most famous outspoken dyslexics.  Apparenelty he struggled in school, a lot, but found success in acting.  In 2003, he started a book series called Hank Zipzer, about  kid in elemtary school who has a learning disability - but he is also very smart, creative and resourceful.

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."

For those of you looking for technology to help, look no further than The Reading Pen.  It's a portable learning tool designed for students of a second-language as well as for children and adults with reading difficulties (such as dyslexia). The perfect solution for increasing reading autonomy and fluency, and enhancing text comprehension.

You can easily scan text or insert it using the touch screen and virtual keyboard, hear it spoken aloud and obtain definition, translation, spelling, syllabication and correct pronunciation within seconds. All looked-up words can be transferred to the PC for further practice. Text can also be uploaded from the PC onto this fully mobile, lightweight Pen, and can be read aloud wherever you are.

You can find the details at http://www.wizcomtech.com/eng/catalog/platforms/01/default.asp?pCat=8&PlatformID=22.  Prices are between $200 and $400, but well worth the money.

As we all know, it can be tough to get your child to read.  Reading might be tough enough for them when they have to do it, so how can you get your child to read every night. 

There are a few things that I have found very helpful. 

First, turn the TV off and read.  Showing your kids that you are reading is the best way to model.  Even if you don't like to read, do it.  Second, read with your kids every night in bed - every single night, except maybe Friday and or Saturday.  Having him read and page and then you read a page really works well.   Then sitting in bed for for a few minutes in bed while you each read seperately. 

Finally and perhaps most importantly, find some things that your child likes to read.  Find books that he picks out and then give him some choice.
