Can the color-blind really see?

Still no decision on whether I want to quit the 'Bob and start on something new, but I did reset my iMini last night (thanks for the suggestion, Mom), which fixed whatever was broken and now the select button works.
Ugh. In my color-blinded eyes, Thousand Island dressing can sometimes look like Caesar. Now my salad has a sickly sweet flavor that I was not intending it to have. Isaac Newton discovered that when you pass white light through a prism, the prism actually splits the light into all it's various components, creating a rainbow effect. My eye (or perhaps my frontal lobe) can not perceive this effect in it's entirety, due to a recessive gene on my X-chromosome. I had heard once that researchers had discovered a correcting lense that could be used to give the color-blind sight. Do they have this as a consumer product yet, or am I only imagining I ever heard of this discovery?
Perhaps I should write to the Mythbusters about it.
