Alright. Our example says that while walking through the woods at night, you realize that you can see things better if you don't look directly at them. In a single sentence, why might that be? And the table is provided as a reference. Alright. So this table cues us into what our answer is going to be about, our rods and our cones. As we go through this table, well, we have many rods and we have few cones. That's not going to be related to this. The rods are in the periphery. Our cones are in our center of vision. Alright. That seems like it's going to be part of our answer. Right? So in our peripheral vision, you have more rods, and, in fact, you have no rods in the center of your vision. Most of your cones are in the center of your vision. But, here, we're saying you're going to see things better at night if you actually look just to the side of them, if you use that peripheral vision. Alright. So that's going to be part of my answer, I'm almost certain, as I go down. I see here that rods function best in low light, and cones, remember, require very bright light. So if I put these two things together, I get my answer. If I'm walking through the woods at night, it's low light, I need to use my rod vision, but I have no rods in the absolute center of my vision. So if I want to see something really clearly, I actually can't look directly at it. I have to look just to the side of it, so that that light is hitting just to my peripheral vision where my rods are. In bright light, right, you have enough light, it can stimulate the cones, you want to look right at something. Okay. So with that, I'm going to write my answer. I'm going to say that rods see in low light but are located in the periphery. They're located in your peripheral vision, And this is true. You're walking at night. It's easier to see things if you're using your rod vision, that grayscale vision, if you don't look directly at something. So now you know if you're ever going on a night hike and you trip on a stick and you say, what the heck? I was looking right there. Why didn't I see it? Maybe you shouldn't have been looking right there. You want to look just to the side.
