This graph represents the density of rods and cones within the eye. We can see that cones are more concentrated around the center of the eye, whereas rods are abundant across the rest of the eye. This supports the idea of that Ren mentioned in lecture of viewing stars for vividly by viewing from the side of your eye rather than straight on, as rods are more sensitive to light than cones are in dim lighting (when stars would appear). Looking at stars straight on will make it so they don't look nearly as bright, as cones are not as sensitive to light as rods are

@brandonlouie thanks for the comment! I wonder if this has anything to do with why night myopia occurs, when lights appear blurred at night.

From what I can gather about night myopia online, it's mostly caused by 1) our pupils adapting to the dark by dilating (larger aperture --> more unfocused light rays entering) and 2) focusing at near range (so when someone with night myopia looks at far-away objects, they seems blurry). The fact that we don't have great fine-grained vision in the fovea probably also contributes overall to existing night myopia.

In what ways can we modify the eye to perhaps see things that are currently outside the scope of human vision? Are there certain limitations in the shaping of our eye that cannot be overcome, even with modifications?
