As we get older and wiser, we increasingly become aware of how little we know and how technology can be used to make us appear wiser than perhaps we are. To use this technology means increasing reliance on reading information displayed on screens. This can mean reading screens at railway stations, across the room on a TV screen, at arm's length on a desk, balanced precariously on your lap, or held in your hand.
If you are over 40 you will no doubt be starting to notice that your ability to focus easily at any distance is a thing of the past. Glasses that give perfect vision at distance will no longer give you detailed vision for something literally 'under your nose'. One way or another if you wish to use digital screen technology to appear wiser, you will need to use optical technology to appear to have youthful vision.
