What Are the Advantages of Progressive Lens Glasses?
14/5/2010
The popularity of progressive lens glasses
demonstrates to us their advantages. It is an undoubtable question.
However, many people think they are good, seldom delivery this idea to
others. Now I will do this for you.
Progressive lens glasses is more commonly known as the no line
bifocal however it is more than a bifocal or even a trifocal. In
actuality, the progressive lens glasses is a multifocal with many
vision areas. The progressive lens glasses gradually increases or
decreases in power, much like the eye used to, as you move your eyes up
or down the lens.
An increasing number of people who are in need of near vision help
are turning to the progressive lens glasses for their vision needs. The
need for near vision correction happens when the muscles and the
interior lens of the eye begin to loose their elasticity much like a
rubber band does as it ages.
Progressive lens glasses are not designed to have clear vision
throughout the entire lens. In learning to wear progressive lens
glasses you must remember that like an hourglass the corridor is
narrower in the middle than the top and bottom. To use the middle
portion you need to use your nose like a pointer and turn your head
slightly to look directly at your object to get the full advantage of
the intermediate area. If you glance to either side you will run into
the blended area and your vision will blur slightly. To adjust the
power between the distance and the near you must move you head slowly
up or down which changes the power according to how far away the object
or reading material is from you. Generally your near distance is
measured at about 16 to 18 inches or elbow distance. The intermediate
distance is between you elbow and about 6 inches beyond your finger
tips. The far vision is anything beyond the ends of your finger tips.
When wearing a progressive for the first time you must tilt you chin
toward your chest and look over the intermediate blend to see the floor
since it is beyond your fingertips.
This lens has a design much like an hourglass. The line that was
present on a bifocal lens is blended into the outside or peripheral and
the inside or the nasal part of the lens. The space that is created by
this blend is the channel or corridor and that is where the
intermediate or computer distance power is. This is also where the
prescription power gradually changes from distance in the top to the
near in the bottom.
Well, I have shown you the advantages of progressive lens glasses
with my own experience with and understanding of them. Although they
are not designed to everyone, everyone can learn to wear them. Isn’t
that true? Its popularity and advantages have told everything.
