How do prescription bifocal sunglasses/goggles work?

As we already mentioned, a bifocal lens is really two lenses combined into one. Bifocals have a single visible line separating the two viewing zones. The upper part of the line bi-focal lenses correct distance vision and the lower part is for near vision. The driving distance area is designed like a single vision lens, while the near area contains the distance prescription and the additional amount of plus spherical power needed to see at a reading distance. The additional amount of plus power (also called ADD power), for reading is located in an area referred to as the segment. That's why Segment Height measurement is a must when making a pair of prescription eye wear with bifocal or no line progressive lenses. You need to visit your local optician to have him measure the Seg. Height for lined or lineless bifocal lenses in exact rx sunglass/glasses frame (we can always provide our customers with a frame from a trial program). If the lower part of your bi focal prescription sunglasses, the reading segment, for example is placed too low, you will have to bend your neck backwards when reading. The frame should be correctly aligned on your face, especially when lined bifocals or no-line multifocal lenses are prescribed.

Trifocal lens is an extension of the bi-focals. Bifocals lenses provide vision correction only for distance and close up near viewing, leaving the intermediate area between distance and reading uncorrected. The tri-focal lenses provide another segment on the lens above the reading viewing area to correct the intermediate viewing area between far and near.
