Blended Vision or Monovision has been utilised for many years as a reliable strategy to achieve the ability to perform near and distance tasks without the aid of glasses or contact lenses. It is a term coined for those whose non-dominant eye is intentionally focused for near to reduce or sometimes remove the need for visual hardware for close range tasks such as using a mobile phone, reading, sewing and computer work, while concurrently leaving the dominant eye focused for distance tasks such as driving and watching cinema or the T.V.
Blended vision can be achieved with Laser Vision Correction or via Lens Exchange and offers a more permanent solution for those who want to be able to perform both distance and near tasks free from visual hardware.
