Did you know that the human eyes have 130 million rods that detect light in low-level conditions but don’t perceive color or fine details?
There are 7 other million cones that cluster in the middle of the retina. When either fails, people lose sight in all or part of the visible spectrum.
Good news: In a recent study adult male squirrel monkeys, with gene-therapy, were able to gain their vision. This brings hope to those who have congenital vision disorders for both adults and children.
So what science fair project can you do to that will help people who are blind?
