$\small\boxed{Uses Of spherical Lens}$

They are generally used to expand light or increase focal length in existing systems, such as beam expanders and projection systems. Positive Meniscus Lenses are designed to minimize spherical aberration and are generally used in small f/number applications (f/number less than 2.5).

I hope its help for you:)
