You see the world through them, right? And you can tell the difference between the world that’s not there and the world where you are.”
The fact that they are more susceptible to pain doesn’t make them immune to it, he noted. As for the eye’s ability to perceive light, scientists still have a lot of unanswered questions.
“It really depends on what your subject means by ‘eye’. It could be anything; maybe it means a ‘seeing’ or a ‘feeling’ sensation of something, like a sense of sight,” he said. “Maybe ‘seeing’ and ‘eye’ mean something different in two-person interaction, and this is why eye contact is considered more important for intimate contact than for a one-on-one, and why the eye can be involved in nonverbal communication.”
In addition to its effects on the brain, our ability to see, the eye may play a role in our interpersonal relationships.
“I think a lot of interpersonal connections — and some that are a little bit physical — rely on our ability to make eye contact,” he said. “And in those kinds of connection, the eye is a more powerful medium than the mouth, because you can focus on a person’s face and tell them what you mean to them, rather than on what’s on their lips.”
We’re also more vulnerable to the effects of age on vision than we think we are.
“In old age, our vision starts to deteriorate, and the eye is actually our body’s way of protecting itself from those aging processes,” he said. “It has this natural protective mechanism that keeps your eyes healthy and your eyesight going, and that’s called myopic macular degeneration.”
Macular degeneration occurs when your retina becomes smaller, often the size of a pinprick in age, but it can also affect your eyesight if you’re particularly unlucky.
“Sometimes that means it is hard to focus on what you’re focusing on, especially your eyes. And then we’re unable to see it — and it leads to blurry image to your right and your left, and blindness or poor quality vision,” said Rizzo.
“We’re still learning a lot about the effects of aging on vision and how it’s changed since the development of modern medicine, and now we’re going to have a chance to observe that for ourselves and to learn more about those effects.”
