Magnifying glasses are convex lens. The lens with a curved shape is named a convex lens; it has a bulky center and thin edges.
A convex lens bends the light that goes through it toward a focal point. The light spreads out again past this focal point. When you use one, the lens bends the light rays so that they come together and focus on the lens within your eye. The light then spreads out as the rays continue past the focal point, and they hit the retina of the eye. The spreading of the light makes the image viewed appear much larger than it really is because it causes the image to take up more space on the retina. Moving the magnifying glass closer or farther away from the eye will change how much the light is spread on the retina. The closer the magnifying glass is to the eye, the bigger the image will appear.

Can you explain the theory of relativity in simple terms?
Try reading the book Spacetime Physics, by Taylor & Wheeler, published in 1965 and still in print. I read it when I was in High School and found it very understandable. It uses lots of geometry to explain things and avoids calculus. See if your local library has it or can get it for you from another library that does.Even a simple explanation of relativity is too long for this site without introducing distortions and misunderstandings that require even more questions and answers to resolve.
