Let us explain...
Progressive lenses are designed to provide you with all-round comfort: near, intermediate and far. However, anyone who spends many hours in front of a computer every day for work, hobby, etc. will soon realise that all-round lenses do not always provide the desired comfort.
The distance of a screen is +- 80 cm from our eyes. Indoor lenses are therefore optimised so that you will have a very wide vision at that distance. They are, as it were, optimised for such spacings.
The Indoor lenses thus offer you the perfect complement to your progressive lenses.
