Myopia- Nearsightedness is a common vision condition in which you can see objects near to you clearly, but objects farther away are blurry hence concave lens is used.

Hypermetropia- Long-sightedness, also known as hyperopia is a common vision disorder. It results from the overall power of the eye not being strong enough hence convex lens is used.

Presbyopia- Long-sightedness caused by loss of elasticity of the lens of the eye, occurring typically in middle and old age hence Bifocal lens is used

Astigmatism- It is a common vision problem caused by an error in the shape of the cornea. With astigmatism, the lens of the eye or the cornea, which is the front surface of the eye, has an irregular curve hence Cylindrical lens is used.
