halacha - Re-reciting morning Berachoth

If someone recites the morning Berachoth, are they also situational Berachoth that might require one to re-recite them in a certain situation? Some are definitely regarded as situational, and some have certain properties of being situational, although they are recited even if the situation doesn't actually apply.

For example, I've heard that it is customary on Tish'ah BeAv not to recite "שעשה לי כל צרכי". Also, when a man wearing Tefilin recites "עוטר ישראל בתפארה", it is customary to touch the one on his head, indicating that it is regarded as our "crown".

Let's say that someone is ill with a common and treatable illness, such as strep throat, and is taking the medication (in this case antibiotics). I've never heard that someone with a treatable illness, or any other illness for that matter, should omit "הנותן ליעף כח". So, assuming it's correct to recite this Berachah even when ill, this person does so in the morning as part of morning prayers. But let's also say that this is the person's second or third day on the medication, and some time after reciting the Berachah in the morning, he really begins to recover and is starting to feel much better. (Let's say he was feeling lousy at 7am, but he Davened, and he recited this Berachah, but then later he ate whatever small amount of food he could, he had a nap, and he ate a bit more, and began to get some real energy. By 7pm, he's really feeling almost back to normal.) Could he (or even should he) recite "הנותן ליעף כח" again?

What about a person who wears glasses but cannot find them, or someone else steps on them before he wakes up in the morning? Later in the day he either finds them or gets them repaired. Surely he should not refrain from saying "פוקח עורים" just because he temporarily can't see. So should he re-recite it once he can see again?

Take the glasses example a step further. Let's say someone has a minor eye injury or a migraine headache that can cause sensations similar to blindness, but later can see again. Should he then re-recite the Berachah?

Finally, there is an opinion that, along with שהחיינו, a person should recite "מלביש ערומים" when wearing new clothes. If there is such a requirement, does that follow even if someone has already recited this Berachah in the morning as part of the standard Davening?

I know that one can always recite these without "Shem UMalchuth". What I want to know is, is there a standard, accepted rule (even if not universally held) that one repeats the Berachah?
