Distance, Reading or Single Vision lenses
Single vision lenses have your distance prescription power throughout entire lens, or reading prescription power throughout entire lens, or any other specialized prescribed power (such as computer distance) throughout entire lens.
Bifocals lenses have distance prescription power on upper portion of lens and lined segment with reading prescription power on bottom portion of lens.
Progressives lenses are invisible (no-line) bifocals. Prescription power for reading “progressively” increases from distance prescription on upper portion to reading prescription on bottom portion. It essentially performs similar to a trifocal, but with a smooth transition from distance to near.
