progressive lenses

These are “no line” bifocals.  They look like normal glasses, but the further you look down the stronger the bifocal “progressively” becomes.  This type of bifocal is useful for active people because you can literally tilt your head to appropriately focus on different objects. For example, you might look through the top part of the progressive to see your car speedometer, and look further down to see your phone. Progressives aren’t for everyone, however.  Some people don’t like them because the bottom part of the glass seems distorted when walking around.  Also, the “sweet spot” for crisp reading vision is much smaller than a traditional bifocal, which can be annoying for long periods of reading. They also cost a little more than a traditional bifocal or trifocal.  There are several brands of progressive lenses, but generally the Varilux brand is the highest quality model that seems to provide the most comfort for a majority of users.
