Hi again, Alan and thanks for your reply.
If the scratches are quite deep, it would be best to bring your glasses to the place where you bought them or to an optician's office and find out if they can be repaired. Light scratches may be gotten out with this recommended method:http://www.ehow.com/how_7501004_repair-scratches-transitions-lenses.html
The grease pencil mentioned, is also called a 'white Sanford peel-off china marker'.
I think the cloth you're thinking of is either a microfiber cloth, as recommended at the site above, or a chamois cloth (also called a 'shammy' cloth), which is very soft and does not leave lint.
However, if your glasses have an anti-reflective coating, using the above method will worsen their condition, so don't use it.
If the scratches are bad enough that you see a foggy-type effect, unfortunately, you might have to replace the glasses.
