Reader – natural viewing when working at a desk or in a space with widest near and mid-range vision zones

Indoor lenses Reader are intended for near viewing with entended vision zone. These lenses are also very suitable for mid-range work, where glasses for near viewing are unsuitable and where progressive lenses have limitations in the width of vision zone. They have very little lateral distortion.


Indoor lenses Reader are a great addition to progressive and bifocal lenses, as they offer freedom to the user when working on a computer, at a desk, reading or doing domestic activities. They are recommended for all indoor activities.

Unifocal (single vision) lenses Reader

Short vision zone forces the user in unnatural and exhausting position Extended viewzone allows user to have natural and relaxed position also by long time use of spectacles with lenses Reader


Purpose of use

  • ideal for users who spend a lot of time viewing at near and mid-range distances (computer, reading and indoor work, office, cooking, painting, music)
  • the best lens for office work
  • not suitable for distance viewing (sports, driving, …)



Reader lenses come in three variants:


Ideal for users who mainly view things up to 1.33 meters far. Due to low reductions (degressions) the vision zones are extremelly wide, working on a computer is very comfortable, monitor view is excellent.

Purpose of use: close up work and mainly working on a computer, even with a larger monitor.


Balanced design for users who demand sharp vision for near viewing and at a desk. Reductions are slightly larger than at the Monitor variant, and enable viewing of up to two meters. Especially suitable for users who work with customers, e.g. in a shop, bank, office …
Purpose of use: close up work, computer, viewing at mid-range distances.


For users who need sharp vision for close up and indoors. Longest viewing distance is four meters. Slightly narrower vision zones, which is why we don’t recommend these lenses for widescreen monitors.
Purpose of use: close up work, indoor viewing.
