Single-vision lenses are only used for a specific distance range and generally only correct either short-sightedness or long-sightedness.
These include, for example, so-called distance glasses for the best possible vision at maximum distance. Reading glasses are an ideal solution for correcting good vision at close range (usually up to around 40 centimetres). However, single-vision corrections can also be made for all intermediate distances, for example for screen work at a distance of around 60 centimetres.
Single-vision spectacles are advantageous if a visual aid has to be used over a certain period of time and within a roughly constant distance. If you do not want to take off or change your glasses for different distances, we recommend wearing varifocals.
