Is there a link where a guy ccan find out the fundamentals of binoculars, eg. how they work, what the numbers mean, what is good for certain uses?

I am looking to buy a pair for the window sill in our home. Just for looking and not much else but don't want to spend much money.

Look no farther - you have arrived.

The first number in a binocular, the 7 in a 7x35 is the magnification. In other words, this binocular will enlarge an image by a factor of 7. Most binoculars sold today have a magnification of 7x to 10x. For what you describe, a magnification of 8x would be fine.

The second number in a binocular, the 35 in a 7x35, is the size of the front lens in millimeters. Compact binoculars will have a front lens of 20-25mm, whereas full size binoculars will have front lenses between 40 and 50mm. For what you describe, a 40 or 42mm front lens would be about right.

Here are a few casual use binoculars that won't require a second mortgage.

Bushnell Natureview 8x40, ... eview.html

Meade 8x42,

If you have any more questions, please let me know.
