But when the story is carrying me along, I tend to ignore the cosmetic mistakes, and completely forgot about them.

That happens to me as well, but unfortunately this one didn't carry me along as it did for you. Not nearly enough logical background building, and I got the feeling she was more familiar with fanon than canon.

As to the eyesight, I expect he's farsighted as well. The qualifications say eyesight has to be near perfect; it doesn't say whether near- or far-sightedness makes a difference. He would have been denied on that basis alone and it makes perfect sense why. All too easy for glasses to be broken or lost in a fire fight.

Until the next one, then.
