David Pogue talks optics at CES 2016

One of the free talks at CES was given by David Pogue, in which he shared some very interesting lifehacks from his “Pogue’s Basics” series books.  His tip for when you’re having trouble reading distant signage and have forgotten your glasses is to simply make a fist and peer through the tunnel created by your curled fingers.  It works very well, because in stopping down the aperture in front of your eye, depth of field is increased and spherical aberration, coma, and astigmatism are reduced.  Another piece of advice was to change fonts when reviewing your manuscripts so that the text looks foreign.  You’re more likely to catch errors that way.  Very practical and entertaining talk.  The session was held at the beautiful Venetian Hotel in Las Vegas.
