Progressive lenses have marked a new stage in vision
correction. For the first time, those with visual disturbances at different
distances can take advantage of a single solution that allows you to see
objects clearly both from a distance and up close. However, comfort and
adaptability to this type of lenses, in some cases, still pose a challenge .
This difficulty of adaptation is accentuated if very
different prescriptions are needed between one eye and the other ; this
condition can lead to discomfort with the use of progressive lenses. For a
number of reasons, in particular comfort and adaptation, in some cases, it may
be difficult to switch from single vision glasses to those with progressive
lenses .
The binocular harmonization technology (BHT), which you can
find in the latest generation progressive glasses, offers a new twist as it
solves the discomfort caused by the different prescriptions between the two
eyes.
In this article, we will analyze how this technology works
that allows you to switch to multifocal glasses, even in the most complex
cases, limiting the perceived discomfort.
Different requirements in both eyes

progressive glasses with BHT
technology. Is BHT technology the right choice for you?
Different
prescriptions in the two eyes
The different prescriptions applied to progressive lenses
represent a challenge to their proper functioning. Yet, according to the data
of European manufacturers, in the last 10 years, 70% of wearers of progressive
glasses have different prescriptions between the two eyes , therefore it is a
very common situation.
Binocular harmonization technology (BHT) represents the
solution to this challenge . BHT is an innovative solution that considers the
difference in prescription between the right eye and the left eye to calculate
the optimal design of progressive lenses , ensuring that the distribution of
the gradation and the length of the progression channel of each lens are
exactly what that the eye needs.
Progressive glasses
of the latest generation with BHT technology
BHT technology makes your progressive lenses more
comfortable, in case you have different prescriptions between the two eyes. It
is effective with small and large differences between the two lenses, but also
with strong or weak corrections . This innovative technology helps to read for
a longer period of time, without fatigue, allows you to devote more time to
digital devices and decrease stress when changing focus over different
distances, as happens when passing from near to far.
The BHT technology for progressive glasses of the latest
generation specifically helps to relieve the tension and discomfort that can
occur in various ways. Common symptoms include :
Headache
Difficulty focusing or moving from distant objects to nearby
objects
Blurred or split vision
Dry and tired eyes
Burning, painful or tired eyes
These symptoms can be caused by a variety of things , such
as an inaccurate prescription, the wrong type of spectacle lenses, prolonged
use of digital devices or
activities that require continuous focus, such as reading. The Your optometrist
can help you determine the root cause that triggers these symptoms and provide
you with professional support to eliminate them by choosing the best among the
available lenses.
So how does BHT work?
BHT technology takes prescription for both eyes into account
when building your glasses. By designing the lens design , we make sure that
both eyes have adequate and balanced support, to ensure eye comfort in all eyes
. Since with this technology your eyes work perfectly together, without having
any hassles or disturbances, you will be able to use progressive glasses in
comfort.
Is BHT technology the
right choice for you?
You are probably wondering if BHT is the right choice for
you and how you can proceed to get it.
The first thing to note is that this technology is designed
for presbyopes , that is, for people who need progressive lenses. You may not
be familiar with this visual disturbance and may not know exactly its symptoms
and causes.
Briefly, presbyopia is a physiological phenomenon that
occurs to all of us around 40/45 years old and we notice this change because it
becomes more difficult to read closely and we feel the need to help us with
reading glasses . To have a good correction of the problem, it is necessary to
take into account any differences in gradation between the two eyes, a
phenomenon known as anisometropia.
The first thing to do in these cases is to consult vision professionals, then
ophthalmologists, optometrists and opticians.
These professionals will be able
to work with you to determine whether BHT technology can bring specific
benefits for you and what the options are for your glasses.
BHT technology is in fact used in premium progressive lenses
and you should consider the various choice and customization options for your
latest generation progressive glasses , so that they perfectly adapt to your
lifestyle and your needs.
Your optometrist will be able to take into consideration
your visual needs , prescription, lifestyle and any other considerations, when
he will help you choose the right glasses for you. In fact, as progressive lens
technology has improved dramatically in recent years , superior quality lenses
can be customized taking into account how you spend your time.
In conclusion, this allows you to have a truly satisfying
visual solution and to minimize the initial effort of adaptation, without
risking encountering obstacles due to the different gradation of your eyes.
