Bifocal glasses use 2 types of lenses connected together in 1 lens. Typically, the top half of the lens is used to see objects from far away, especially when driving or walking. The bottom half is a smaller portion of the lens that is used to see objects nearby, such as a book or newspaper. With these side-by-side lenses, patients can easily shift between the 2 prescriptions to comfortably continue their daily life. For patients with greater vision concerns, a doctor may suggest investing in trifocal prescription glasses. This lens uses distance, near, and intermediate vision correction.
