Possible Brain Issues w/ Milk Snake?

[Cricket1234]

Ah yes, another post from my over-worried self. Here goes nothing!
So my young Pueblan has been feeding good, and I have had no issues so far. (Which I am VERY thankful for) But my milk Snake has always had trouble feeding on his mice. Ever since his first feeding, he has been miss-striking at his food. It normally takes him up to 5 strikes to grab onto his mouse, and often he will make contact with the mouse but quickly draw back. Today was an exceptional day, with him at least striking 20 times at the prey item, and let go of it once or twice as well. I am pretty sure this is because he is going into shed, and he still has his blue eyes, which clouds up his vision. (Correct me if I am wrong) But I am almost positive that this behavior is not normal, and could indicate something mentally wrong or something wrong with his vision. What are your guys opinions? I do not really observe any other symptoms than that though. What are your guys opinions on the matter? Thanks and have an awesome day!
