Erdős–Turán conjecture on additive bases
Is there a link between vision and learning? If one can see the print, is that the extent to which vision http://tinyurl.com/kecvhhb is beneficial, or does the process of learning require more than just the ability to see print?
When some Optometrists test a child with learning problems, the result often conveyed to parents is something along the lines of, "This child has 20/20 vision", cheap ugg boots or "This child sees perfectly well." The underlying implication is that, if a child can see, they should be able to learn, but anyone who's worked with learning disabilities as long as I have realizes that nothing might be further from the facts!
The Relationship Between Vision and Learning
Let's be clear from the outset, sight and vision are different. Sight is whether or not a kid sees the print, but vision goes beyond this, taking into consideration how they understand, interpret and absorb visual information. Let me illustrate. I am a fairly intelligent guy, university trained and quite experienced in life.
My distance vision is good (20/20 at the least), yet for a recent trip to Singapore, http://tinyurl.com/kecvhhb I saw a street filled with signs in Chinese, and I could not understand ANY of them! Not even one. I saw just fine, but could not even attempt to pronounce them, not to mention understand them!
In a sense, I don't possess the code for the written Chinese language. I can see it, but I cannot understand what the symbols mean. I can even copy it, but http://tinyurl.com/kecvhhb it really is without meaning to me. And for many children with learning problems, they experience something similar with English words.
Improve Vision and Learning Can Improve Too
If a child sees the print, I cannot really develop their sight. But if a child struggles to maintain their focus, or coordinate their eyes like a team, or if they can not remember the code or symbols, these we will help with. If they misread, mix up words or struggle to concentrate, this we can also help.
We can improve reading, writing and spelling but helping the kid to look at http://tinyurl.com/kecvhhb and absorb visual information comfortably and effectively. As a behavioural optometrist, this is exactly a place My group is obsessed with and may create a difference in in your child. We may help them overcome incredible odds in learning by improving their vision, versus just working with sight alone.
Frequently, the key about solving learning difficulties is improving a child's vision, and visual skills, and these two combined can prove the definite link between vision and learning.
