Bifocal specs have long history of serving eye problems of human
beings. They are in ever development to treat more complicated and
specific eye problem. They have combined function of correcr both
presbyopia and near-sightedness and farsightedness.This can also be
considered as the most significant improvement compared with regular
reading glasses. In fact, bifocal specs have been continuing its
progression after making such a significant breakthrough. For certain,
the basic design principle will not change as its name suggests. A pair
of bifocal eyeglasses will provide those basically two forms of visual
aids for ever. However, a lot of new, specific designs have been brought
into existence during the past years since its origin. Currently, all
lens designs of bifocals can be grouped into two mainly categories:
Franklin bifocals and bifocals with reading segments in a small size.

The first category is bifocal lens designs taking reading segment as
the fundamental concept. Bifocal specs within this category all take use
of reading segments molded into a primary lens. These different designs
differ in the shape and position of the reading segment. For instance,
available shapes include half-moon or D shape, round, narrow rectangle
and so on. While most reading segments are situated in the lower part of
the lens, there is a special design called double-D that molds two
reading segments into the upper and lower sections respectively. Bifocal
specs have developed several different designs after more than two
hundred years' progression. There are mainly two categories,
respectively the Franklin bifocals and bifocals with small reading
segments.

The second category of also the original bifocal design. This initial
form was developed by Benjamin Franklin by cutting two lenses in half
and combining them together. So, a bifocal lens of Franklin's style has a
half portion for reading and the other half for distance vision. Using
these bifocal specs, wearers can naturally look down to read materials
and look up through to view objects in the distance. All things seem
good and feasible. One point of this simple design is that these two
focal points have been fixed into each half part. In some cases, it is
inflexible for certain users to perform customized visual tasks. The
current situation in the market is that bifocal reading glasses of this
design can seldom be seen. There exist more flexible and helpful
designs.

This is the basic categories of bifocal specs. If you are interested
in these glasses, it is useful to know about their types then you hae
more possibility to buy the most suitable one for yourself.

When people have advices to wear bifocals or trifocals, they may have
new problems like image jump which will influence wearing experience
and cause harm to eyes at some extent. Fortunately, there are progressive reading glasses
with advanced designs to solve these problems. Since progressive
eyeglasses use lenses with a gradient of increasing lens power, a
significantly smoother power transition will be offered. It is
reasonable to claim that those no line bifocal reading glasses have made
a noticeable improvement, compared with those traditional bifocal
reading glasses. Most historians or scientists have reached an
acknowledgement that the first pair of bifocal spectacles was created by
Benjamin Franklin in around 1784. However, few people know the exact
origin of the progressive addition lenses.

The first commercialized PAL product was proven to be developed in
1922 by Duke Elder, marketed by Gowlland of Montreal as Ultrifo. These
lenses took use of an arrangement of aspheric surfaces. In fact, the
first PAL of modern design was developed only by 1953, under the name of
Varilux lenses. After more than a half centurys progression,
progressive power lenses in the modern time are more sophisticated and
have gained greater patient acceptance. There have been also many forms
of progressive reading glasses offering customized designs for special
groups of patients. Most of the manufacturers now use computer
controlled machines to cut and polish the surface of progressive lenses.

In 1907, Own Aves was granted with a British patent for a PAL, which
was considered as the emergence of progressive addition lenses. This
initial version of progressive lenses included progressive lens design
as well as manufacturing process. The power gradient of Aves progressive
lenses was achieved by making a conical back surface and a cylindrical
front with opposing axes. This was considerably different from the
modern design. It was a pity that this design never gained
commercialization. And progressive reading glasses were not available at
that time.

In other words, progressive reading glasses are another version , an
advanced version of bifocal reading glasses, which were invented earlier
than them. They may have their own shortcomings. However, modern
progressive addition lenses are quite sophisticated and have gained
greater patient acceptance.

Prescription eyewear has a large market today. The advent of this phenomenon can be explained as follows.

Eyeglasses can be equipped with prescriptions for any type of visual
acuity and fashioned from materials that will create a definite fashion
statement. Some of the prescriptions for eyeglasses require lenses to be
thicker than thinner models and some people choose to wear those lenses
at night when they are less visible than other pairs of eyeglasses that
are for the same prescription.

Most people consider prescription eyewear as a wardrobe enhancer
because there are so many color choices available in eyewear. People
wear colored contact lenses that have prescriptions that allow them to
remain in the eye for weeks at a time. Other prescription eyewear styles
can be chosen and those will need to be changed each day or every week,
which is a fashion choice that is left up to every eyeglass wearer.
Some fashion eyewear styles feature lenses fashioned for reading. Those
are the ones that do not have to worn all day and are the least
expensive eyewear styles on the market today.

The aging process might require eyeglass wearers to change the style
of eyeglasses that are worn on a daily basis. After the age of forty,
many people have found that their eyeglass prescriptions have changed
because seeing images up close or afar becomes increasingly difficult
and these shortfalls are evident after a few minutes in the doctor's
chair. An optometrist will write a prescription for eyeglasses that
features bifocal lenses and patients will have fashionable options while
growing old wearing them. Bifocal lenses can be tinted for an extra
charge or the prescription eyewear can be fashioned with darker tints for wear while out in the sun.

A prescription for fashion eyewear can be obtained for less than
forty dollars. Some eyewear manufacturers can create fashion eyewear in
less than one hour and maintain the prescription quality in every pair
that is created. Other prescription eyewear can be obtained which will
require another type of prescription. Contact lens wearers will receive
special measurements during the eye exam to ensure that individual lens
sizes are matched perfectly. Both prescription vision styles can be
outfitted with lenses that are luxuriously colored.

The fashion opportunities for designer eyewear are unlimited and
people are adapting prescriptions to meet many frame shapes. The frames
for prescription eyewear can be purchased in one color or the wearer can
choose several to add a bit of individuality to the eyeglass wearing
experience. Prescription eyewear styles are changing all of the time and
many people prefer to keep more than one pair on hand at all times.
Prescriptions for eyewear should be obtained every two years and most
people look to this as a fashion necessity that is very affordable to
comply with.

Some prescriptions for eyewear will require hi-index lenses. Other
eyeglass wearers might have a preference for wearing lenses that are
progressive. Eyeglass wearers have many choices to make in the eyeglass
styles that are worn each day and many have turned to wearing eyeglasses
that are equipped with lenses that automatically change to sunglasses
whenever the need arises. The prescription for the eyewear will ensure
that people can see but the eyewear styles will ensure that people are
able to personalize the eyewear experience.

All in all, prescription eyewear is undoubtedly tailored to meet the visual and fashion needs of the customer.
