Will you do any harm to your SLR camera lens by cleaning it with an isopropyl alcohol wipe made for "eyewear" type glasses?

Yes, you can clean them in this manner. But first, use a blower brush to remove any loose particles that may be on the lens. You can buy the blowers at most camera supply stores.

Sand can be a real problem and the blowers are made to address that issue. The cleaning cloths made for eyeglasses arealso safe for the glass on camera lenses. Attached is a thread on a Pentax forum that covers this question.It discusses the use of the packs of alcohol premoistened wipes that can be bought cheaply at Walgreens.

There are several sites on the web that confirm this usage.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
