Occupational Lenses
Occupational lenses are similar to progressive lenses, however instead of being set for distance, intermediate and near they are set for intermediate and near. This is very useful at work when your tasks include reading and looking at a computer simultaneously, the intermediate range can be up to about 10 feet.
These lenses are significantly cheaper than progressive lenses allowing an affordable lens to use at work especially if you do not need glasses for distance vision.
