Ft 28 bifocal- Standard bifocal with the line, has the smallest half moon segment: 28 millimeters across. Ft 35 bifocals- Same as the Ft 28 in shape, but 7 millimeters wider (35 millimeters across). Executive bifocals- The line on this lens goes all the way across the entire width of the lens.

This lens contains a distance prescription and an infinite range of intermediate and reading distances. The cosmetics and optics are state of the art. Easy to adjust to, and quickly becoming the lens of choice.
