I’ve seen animals look directly at the sun. I doubt we’d notice a rare case of sun damage in animals. >

Our eyes are also not as good as most animals I think >

better than most animals not as good as some >

This is a false. Our eyes evolve to the purpose of need. It's not a competition. However, only a human could be so arrogant to think otherwise. >

So, evolution does not happen for the purpose of need. Pretend there is an orange species of animal, and a predator. Then a mutation just so happens to occur that makes an animal red (crazy small chance but still). So what may then happen is the red is better at camouflage than the orange so the predator has an easier time finding the orange and dwindling that population (natural selection). Now if they are lucky and the trait is passed on, that is how a species may evolve to be mostly red and a smaller population of orange. Now that's not always how it happens, there is adaptive radiation most common on islands because of the different SEPARATED environments that means 3 different species of one bird may come from the same ancestor however they may mutate like I mention previously and survival of the fittest take over causing animals that came make use of what they have the best will survive the best. That's why 3 different species on one bird may grow to have different shaped beaks depending on the environment.
Hope this clears things up for ya. I'm gonna try and explain it in less but its not a perfect understanding without background knowledge: evolution by natural selection can be defined as the individual didn't evolve but was either selected for or against, this changing the consistency of the population >

evolution does happen for the purpose of need.. that's the whole point of evolution. if being red was useless and made the animal die more often it would be a less common trait. evolution is either positive or neutral, no species wants to waste energy producing a body part or acting a certain way if it doesn't benefit their needs >

Your first sentence, "evolution does happen for the purpose of need" is kinda construed in a confusing way. There is no, I have run out of food therefore I must evolve, some species do end up mutating in time but it's possible that the species just dies off with nothing to eat.
Your second sentence is what I said in my first comment.
Your third point that evolution can either be positive or neutral is only part of the truth. If you are referring to evolution as a general term it can be bad in the way we have an appendix because right now it is useless to us and only causing problems, there are no benefits of having an appendix. And if we did evolve out of need, we haven't needed our appendix for thousands of years and all it's ever done to us is kill us. However, If you are referring to mutation, mutation can be just as bad, most mutations that affect prenatal are very deadly to the baby. Another example of when a mutation can be bad is if the environment suddenly changes that causes this new mutation to stick out more to predators or something else.
And finally mutation is not, I want this, or I don't want this, It just happens to you. If you have to spend more energy eating with your mutation, you're likely to die off with natural selection aka survival of the fittest which is why every time an animal mutates, it does not mean they are more likely to survive.
Edit: I know this because I am in a zoology college class right now and am an animal science major >

what you're saying is exactly what i'm saying lol. obviously it's not an immediate need, but if a species is struggling to win food over its competitors, evolution will eventually fix that problem. the whole appendix thing is generally neutral, because if it functions 'correctly' throughout your life, you won't suffer bc of it
