Nature Park Installs Colorblind-less Viewfinders

For decades, technology has paved the way for treating detrimental illnesses such as HIV and leukemia. While some conditions remain without a cure, therapy and devices have made everyday living more bearable. A Tennessee nature park gave back to its colorblind visitors by installing a special viewfinder.

“To realize, through red/green deficiencies and other forms of colorblindness, there potentially are more than 13 million people in our country alone who cannot fully appreciate the beauty our state has to offer, we wanted to do something about that,” [said Kevin Triplett, the commissioner of the state’s Department of Tourist Development.]

The colorblind-less viewfinders alleviate specific color deficiencies, allowing tourists to marvel at the park. In the fall, trees don an incredible concoction of reds and yellows, a first sight for some.

“I’m glad to have seen it. I just wish I had seen this all my life,” [local Jim] Nichols said through tears. “Kinda like what I would imagine the difference between here and heaven.”

Positive responses from colorblind sightseers had the state installing more viewfinders across other parks. And there you have it — never take your senses for granted. Not everyone can enjoy them the way we do.

Woman With Extra Cone Cell Can See More Colors

While we’ve been off creating synthetic retinas and talking cameras for the blind, this woman’s vision is far from lacking. The UK native has an extra cone cell, which means she can see far more colors than a typical person can.

According to estimates… she can see an incredible 99 million more colors than the rest of us, and the scientists think she’s just one of a number of people with super-vision, which they call “tetrachromats”, living amongst us.

Most people are trichromats, able to distinguish around 1 million colors. Mammals and sufferers of color blindness are dichromats with only two cone cells. The apparent reason researchers have only discovered a single true tetrachromat is because people with this special vision would never need to use their fourth cone cell.

“Most of the things that we see as colored are manufactured by people who are trying to make colors that work for trichromats. It could be that our whole world is tuned to the world of the trichromat.”

In short, our world of colors is just too primitive for tetrachromats. We may ever know what things look like through the eyes of one, but it will allow for better seeing aids.
