I am looking for a bifocal glasses online and wanted to have a thinner lens. Now, my problem is, I do not know what lens options to choose to get a thinner lens. There are different packages that I don't really understand.

High-index lenses can be much thinner and lighter, even in a strong prescription. The advantages of High-Index Lenses:

Thinner. Because of their ability to bend light more efficiently, high-index lenses for nearsightedness have thinner edges than lenses with the same prescription power that are made of conventional plastic material.

Lighter. Thinner edges require less lens material, which reduces the overall weight of the lenses. Lenses made of high-index plastic are lighter than the same lenses made in conventional plastic, so they're more comfortable wearing.
