I assume that the the question deals with concave and convex lenses. Light rays entering a flat surface and exiting a convex side of a lens will be spread apart enlarging the image. Light entering a flat surface and exiting the concave part of the lens will make the image smaller at close distances, then invert the object at greater distances. There are combinations of lenses that make the image more complex to describe. Now I must add it does matter what distance the image on a screen is from the source as to how the source appears. To know this you need to know the focal length of the lens. If f is the focal length the lens maker uses, and o is the object projecting light's distance from the lens and i is the distance we observe the object after it passes through the lens, the 1/o+1/i =1/f.

Difference between static electricity and dynamic electricity?
There are two types of electricity; dynamic and static electricity. The main difference between these two types is that in static electricity, the electrons do not move but in dynamic electricity, the electrons move either in changing directions or in one direction.
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 are the types of lenses?
There are two types of lenses - fixed focal and zoom lenses.
Is there a difference between adult contacts and regular contacts?
There is no difference between adult contacts and regular contacts. There are two kinds of contact lenses; extended wear and disposable. There are also colored contact lenses.
