However, some people lose the ability to see far/near objects, for them, a concave/convex lens (resp.) works as an auxiliary source to fulfill their lucid vision dreams. A concave lens is a diverging lens that helps people see objects at a great distance if they are dealing with myopia; However, for people dealing with hypermetropia, a converging lens, a convex lens, is used, which we will discuss in this article. We will also discuss the uses of concave and convex lenses along with the use of concave lenses. Read further to know uses of concave lens   Concave and convex lens We find the use of a concave lens in the treatment of vision-related problems and for that, we find the use of a concave lens in daily life; Let's understand how: A concave lens is used to treat myopia because the lens separates the parallel light rays coming from distant objects. Therefore, ...
