If the rods in your eye were selectively damaged by the supervillain, you would experience reduced vision in dim light and an inability to see color. This is because rods are responsible for vision in low light and do not detect color, while cones are responsible for color vision and work best in bright light.
If the cones in your eye were damaged instead, you would experience reduced color vision and an inability to see clearly in bright light. This is because cones are responsible for color vision and work best in bright light, while rods are responsible for vision in low light and do not detect color.
It really depends on the individual and their needs. If you are a person who spends a lot of time in low light, you may want to keep the rods intact so that you can still see in dim light. On the other hand, if you are someone who needs to distinguish between colors, you may want to keep the cones intact so that you can still see colors.
Yes, this choice would change if you were a nonhuman animal, since different species have different levels of light vision and color vision. For example, some animals, such as cats, have sharper vision in low light, while others, such as birds, have sharper color vision. Depending on the species and the needs of the animal, they may want to keep either rods or cones intact.
