There are many companies that manufacture optical lenses, but as with many technical items not all lenses are made to the same standard.
For example, a high index lens made be Nikon is likely to be of a better quality than a high index lens that is cheaply made by a generic lens manufacturer, will not have the guarantees or the level of quality assurance that a Nikon lens would be put through before you glasses are given to you. These are often the lenses you would get for free with a pair of spectacles
