Since spectacles were devised in Italy in the 13th century, there have been hardly any developments in eyesight rectification. In truth, portraits of spectacles-wearers illustrated in the 1400s show what look a good deal like NHS glasses. Contacts have only been around since the 1950s, although Leonardo da Vinci showed foresight by outlining some early examples in his notebooks.

If you are a short-sighted sportsman or woman, work in a dusty workplace or suffer from dry eyes, wearing spectacles or Contacts during the day may not be an option. The Ortho K system – Contact lenses that correct near sightedness while you sleep – could offer a solution. What happens is that you wear the special gas permeable Contacts at night and it somehow reshapes the clear covering of your eye (cornea) to correct your visual imperfectness and give you perfect vision when you arise from your sleep. The visual benefit can be found for at least 24 hours and sometimes a little longer – so you have to keep on to use the product every night. They are waterproof – so if you swim – they could still be an option for you. Although the lenses don’t cure short sight, some studies have indicated that using them may slow down the progression of shortsightedness. This treatment is now within the reach of most people’s pockets, although it has been around for about 5 decades now.
