all began with Benjamin Franklin bifocals invention, the
first pair of glasses of it’s kind that incorporated two
different powers in each lens, for near and distance
corrections. Since then there have been hundreds of
designer bifocals styles available for a man, woman or child
with even more advancements than you can imagine. They even
make contact lenses with bifocal technology as well as
bifocal safety goggles for work or sports.
If you are wondering about the history of bi-focals
or how they work, the Internet is a great resource almanac
to start with. Basically, bifocal lens work by using two
different prescriptions together on one lens usually placed
above one another. As people age so do our eyes and because
of that we tend to have different levels of focus, making it
hard to read or write but having no problem seeing things at
a distance.
Some popular bifocal glasses on the market
today include no line bifocal, Acuvue, press stick on lenses
and progressive bifocal lenses. Many online bifocal dealers

prevent eye disorders like “dry eye”, Presbyopia or
cataracts in older folks and even find some sites that have

pair.
