Christians? Annoying? - I think so.

As Frank Zindler (former professor of biology and geology) stated,

"As an organ developed via the opportunistic twists and turns of evolutionary processes, the human eye is explainable. As an organ designed and created by an infinitely wise deity, the human eye is inexcusable. For unlike the invertebrate eyes, the human eye is constructed upon the foundation of an almost incredible error: the retina has been put together backwards! Unlike the retinas of octopuses and squids, in which the light-gathering cells are aimed forward, toward the source of incoming light, the photoreceptor cells (the so called rods and cones) of the human retina are aimed backward, away from the light source. Worse yet, the nerve fibers which must carry signals from the retina to the brain must pass in front of the receptor cells, partially impeding the penetration of light to the receptors. Only a blasphemer would attribute such a situation to divine design!
Although the human eye would be a scandal if it were the result of divine deliberation, a plausible evolutionary explanation of its absurd construction can be obtained quite easily--even though we can make little use of paleontology (because eyes, like all soft tissues, rarely fossilize)."
