In summary, lenses magnify objects by bending and refracting light. The two main types of lenses that can magnify are convex lenses and concave lenses. The magnification power of a lens is a measure of how much larger an image appears compared to the original object. Lenses can magnify both near and far objects, with the magnification power being determined by the focal length and curvature of the lens. However, there is a limit to how much lenses can magnify, which can be affected by the quality of the lens and the amount of light available.

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.
 

Related to Lenses question -- Can lenses Magnify?

1. How do lenses magnify?

Lenses magnify objects by bending and refracting light. When light passes through a lens, it is bent and focused, creating a larger or smaller image depending on the type of lens used.

2. What are the types of lenses that can magnify?

The two main types of lenses that can magnify are convex lenses and concave lenses. Convex lenses, also known as converging lenses, are thicker in the middle and thinner at the edges. They magnify by converging light rays towards a focal point. Concave lenses, also known as diverging lenses, are thinner in the middle and thicker at the edges. They magnify by diverging light rays away from a focal point.

3. What is the magnification power of a lens?

The magnification power of a lens is a measure of how much larger an image appears compared to the original object. It is calculated by dividing the image distance by the object distance. The unit of measurement for magnification power is "x". For example, a magnification power of 2x means the image appears twice as large as the original object.

4. Can lenses magnify both near and far objects?

Yes, lenses can magnify both near and far objects. The closer the object is to the lens, the larger the image will appear. Conversely, the farther the object is from the lens, the smaller the image will appear. This is due to the different focal lengths of lenses, which determine the magnification power.

5. Is there a limit to how much lenses can magnify?

Yes, there is a limit to how much lenses can magnify. This limit is determined by the focal length and curvature of the lens. If a lens is too curved or too thin, it may distort the image or cause it to appear blurry. Additionally, the quality of the lens and the amount of light available can also affect the maximum magnification power.
