Can lenses Magnify? i know that eyeglasses can get the image farther or nearer to fix it on the retina, but can lenses magnify as mirrors can ?

Have you ever used a "Magnifying glass"?

Try Googling with the search terms "Magnifying Lens" in Images. There are thousands of pictures and many of them show well how magnification is achieved.

You will see that a convex lens is required and that a concave lens never magnifies.
