An Executive trifocal lens is a specific style of multifocal eyewear that provides vision correction at three distances: far, intermediate, and near. Its defining feature is that the lines separating these zones extend across the entire width of the lens. This design is also sometimes called the Franklin style.

Unlike standard trifocals where the reading and intermediate zones are contained in a small 28mm or 35mm segment, the Executive segments go from one edge of the frame to the other. This gives you the widest possible field of vision without having to turn your head.
Trifocals are designed to solve the problem of "intermediate" vision. This is the arm's-length distance used for computer screens, dashboards, or sheet music. The middle segment of the Executive lens is dedicated to this distance. Because the segment is so wide, it is particularly useful for professionals who need to scan large workspaces or multiple monitors.
While they provide excellent vision, Executive trifocals have some cosmetic drawbacks. The lines across the lens are very visible and create distinct ridges on the front surface. This design also tends to result in a thicker and heavier lens, especially at the bottom edge. For this reason, they are usually chosen for function rather than fashion.
This lens style is an ideal choice for specific tasks and professions. Architects looking at large blueprints, accountants working with wide spreadsheets, or musicians reading sheet music on a stand often prefer the Executive trifocal. The ability to move your eyes side-to-side without hitting a blurry zone is a massive advantage for this kind of detailed work.
Unlike standard bifocals where the segment is fused into the lens, an Executive lens is often ground from a single piece of material. This creates a distinct, physical ledge that runs across the entire front of the lens. Wearers should be aware that this ridge can collect dust and dirt. It requires careful cleaning with a microfiber cloth to prevent debris from building up along the step.
Yes, although they are less common today than progressive lenses. Many optical labs still make them because they are the best solution for certain visual needs.
It is generally not recommended. The thick ridges on the lens edge can make mounting them in a rimless frame difficult and less durable. A full-rim frame is usually the best choice to hide the thick edges.
Yes. Because the optical centers are different in each zone, you may notice objects seem to "jump" or move as you look across the line. This is more noticeable in Executive lenses than in other styles.
If you struggle with your current glasses because the reading or computer area feels too narrow, ask your optician about Executive trifocals. Explain your work environment and hobbies. While they are heavier and have visible lines, the visual freedom of a full-width lens might be exactly what you need to work comfortably.
