| The lenses are deigned to give a steady increase in power from the distance vision at the top of the lens - which allows you to clearly see anything that is more than a couple of feet away, to as far as your eyes can see - to reading vision at the bottom of the lens.
Clear near vision will allow you to read comfortably in a natural posture - so no more stretching your arms out as far as you can reach just to read your shopping list or newspaper. |
