"Hi, I'm Dr. Jim Kirkconnell of Bellevue Eyecare Center in Nashville, Tennessee. When does a person need reading glasses? Well sometimes it really depends on the conditions in which you work or have to read. In general, the old saying is "well, my arms aren't long enough" and so you end up pushing things back. Why does that happen? It happens because if you have a good distance vision, the natural lens in a persons eye, which has to change shape in the middle in order to change focus from distance to up close, it gets less elastic sometime between the ages of thirty-nine and fifty and then you have to do something else, backing things up to where you can see them. This is one indication that you're having a problem. Only seeing things that are of headline print and not seeing things of say a newspaper print, six point, eight point. That's probably going to be an indication that you're having a problem. If you have to go out into the bright light in the morning in order to get more contrast, that is one way that you can help yourself without having reading glasses. What that really does is it makes your pupil smaller and it gives a a better depth of focus. And for me, the time came when I was forty-six and I wanted to see my best in the office and so that is the only reason why I wear glasses is because I need reading glasses."
