#Which might seem odd since most snakes aren't known for having great eyesight?

Has Copperhead's eyesight changed at all as his mutation has progressed?

While Copperhead lost the ability to close his eyes, his sight improved significantly, making him able to perceive his surroundings much more clearly in low levels of light than ordinary humans can. Not only that but the cones in his eyes are much more receptive to colours in these conditions - snakes aren't renowned for having great eyesight but Copperhead is built different, quite literally since even in near total darkness, he can perceive blue and green when most other nocturnal creatures are limited to black and white! His eyes are also great at handling UV lighting, be it high levels during the day or low, low levels at night? Copperhead is comfortable operating at either time of day, even when living in sunny places like his native state of Arizona but rapid changes can and will cause temporary blindness since Copperhead cannot close his eyes against sudden flashes. This temporary state of blindness hinders him less than you'd expect; he goes through this during shedding periods, eyes filming up and glazing over when his skin is preparing to renew but getting flashbanged hurts and will almost certainly piss him off. During the day, he can see about as well as a human with perfect eyesight and very good ability to track moving objects, therefore responding much more quickly due to his Metahuman capabilities but it's at night when his abilities truly comes into play, making him a much more formidable hunter when others are stumbling around blind in the dark.
