MSC:
If anything, your OP actually supports the argument that there had to have been an Intelligent Designer aka Almighty God Jehovah.
One of the worst examples you could have used to argue against a supernatural Intelligent Designer/God is the complexity of the eye. As stated by sources:
"The human eye is brilliantly complicated, made up of a superb, interconnected system of approximately 40 individual subsystems. . . . There are approximately six to seven million cone cells. All of them are concentrated near the macula, the oval-shaped pigmented area in the centre of the retina. Additionally, there are three varieties of cone cells that are sensitive to different colours of light. Between them, they span the visual range of wavelengths of the electromagnetic spectrum (400–700 nm)"

But, hark! Let's not forget about the even more complicated creation, the brain, which plays an important role along with the eye to produce vision:
"After an image reaches the optic nerve, it travels along it to the visual cortex in the occipital lobe at the back of the brain. Using our eyes takes an incredible amount of brainpower. 20% of the brain is dedicated to visual processing, but it takes another 40% to help with vision in connection to meaning, motor functions, touch, and attention. Many times a second, the brain absorbs and processes a new set of visual data, and that’s how we perceive, understand, and react to motion."

Now, if you want to claim that all of that happened at random/by itself, without the intervention of an intelligent being to guide the outcome, resulting in vision, suit yourself. In fact, you made it clear in the last paragraph of your OP that it is simply about your personal denials and the fact you don't want to accept the reality of a supernatural Intelligent Designer. You stated at line 1 of your final paragraph. "The Teleological argument has just never sat right with me." That's right. It's all about you and your personal philosophy.
