      @ emmy rayn,
      Hi. I believe the second question I have answered elsewhere? Let me know if you need further clarification.
      Now on electric spectacles. I had no idea they existed! A quick search shows that even though this concept was first proposed in 1850, not much has been done to make these widely acceptable and in use now.
      The concept for these glasses however is the same as that of regular glasses where you have a lens that adjusts the refraction of light to ensure that it falls on your retina. When you have glasses prescribed, an optician tests whether you have near or long farsightedness for instance and prescribes appropriate glasses. Apparently, electric glasses are supposed to test your sight and adjust your glasses appropriately so that you do not need a visit to the optician. At the same time, these glasses should be able to activate your nerves thus correcting sight.
