What is a lens that is thicker at the edges than the middle?

Concave. The opposite- thick in middle, thin at edges- is convex.

That's commonly called a border. Borders can be as thin as one pixel, or as thick as you want !


What is the difference between a thick convex lens and a thin convex lens?

In optics, a thin lens is a lens with a thickness (distance along the optical axis between the two surfaces of the lens) that is negligible compared to the focal length of the lens. Lenses whose thickness is not negligible are sometimes called thick lenses.


What type of lens is used in spectacles to correct long sightedness?

Convex lenses, which magnify, correct hyperopia. Below, is a previous wiki answer to this question in detail.Convex are thicker in the middle and thin out at the edges. These lenses magnify and are used for reading glasses and to correct long-sightedness (hyperopia).Concave lenses are thin in the middle and thick towards the edges. These lenses shrink things and are used to correct short-sightedness (myopia).A good example of this is to take a spoon and look at your reflection in it. Looking at the concave side of the spoon (the front) will make you look smaller, looking at the convex side of the spoon (the back) will make you look biggeRead more: Which_type_of_lens_magnifies_-_convex_or_concave

Why do thick lenss show chromatic aberration but thin lenss do not?

because thick lenses have small focal length . this causes chromatic aberration. hence it can be minimised by increacing the focal length of lens or by using thin lenses which have high focal length.


Do thick concave lenses have longer or shorter focal lengths than thin concave lenses?

It have a shorter focal length because there is more time for the light rays to come together
