Innovative Devices To Help Low Vision Patients - Arohi Eye Hospital

Low vision, as the name itself suggest, is the
condition that involves a vision that is lower
than the normal levels of an individual. But,
this isnt like the normal refractive error of
the eyes that can be corrected with the help of
glasses or contact lenses. In fact, it involves
the least minimal ability to see, which isnt
possible to correct with any such corrective
measures.
This is why science has come up with certain
special devices for such low vision patients,
which can help the individuals use their
residual vision to the maximum, to enable them to
continue reading, writing, and performing other
preferred activities effectively and easily.
These low vision devices can range from simple to
complex, depending upon the needs of an
individual. The simplest low vision devices
include lamp, reading stand, writing guide, and
signature guide. Other devices include
Microscopic glasses

These devices are easily available and
easy-to-carry devices that can help with reading
and writing, and looking at objects from a near
range. These glasses offer a wider field of view
and are thus psychologically acceptable.
However, exact reading distance is important
with microscopic glasses for proper magnification
and clarity. Hand magnifiers These devices are
also easily available and easy to carry.
Available in powers ranging from low to high,
these devices are absolutely inexpensive. They
are helpful to read even the tiniest of things
printed. But, one disadvantage is that these
devices need to be held by hand, thus they
arent suitable for work involving the use of
both hands, such as typing. If you are planning
to use hand magnifiers, remember not to hold the
magnifier close to the eye, but instead, close
to the page, screen, or object that you are
reading from, as this is one thing that people
tend to go wrong with. Stand magnifiers Just like
hand magnifiers, stand magnifiers also help to
read from objects that are close. But, this is
more convenient to use because of the stand that
helps the object to be placed down. Also, the
stand does not make the distance restricted. The
distance between the eye and lens can be
adjusted as required. These devices are very easy
to use, and are available in different powers.
They are also light in weight as they are
basically made from plastic. Stand magnifiers are
great to use for patients with a constricted
field of vision, and for those suffering from
macular degeneration too. But, they may result
in poor posture after prolonged usage. Hand-held
telescopes These devices are useful to read from
objects at a distance. It may help to read from
a blackboard, from an advertisement banner, a
bus number, street signs, etc. The best part is
that these telescopes

are very small in size, lightweight,
easy-to-carry, and very compatible. However, one
disadvantage is that it is difficult to read and
write simultaneously while using a
telescope. Fresnel prism This is a thin
transparent plastic sheet that induces a
prismatic effect, that is, alters the direction
of the image entering the eye. The sheet is
attached to the lens of the glasses you wear,
with the other side consisting of a series of
angular grooves or prisms. These prisms are used
to correct several visual disorders like macular
degeneration, diabetic retinopathy, nystagmus,
and strabismus and are also useful as a field
expander in case of hemianopias. With all such
amazing innovations, low vision patients have
boosted up their spirits and are living a much
better life. You can also use one or more of
these devices to help with your reading hobbies,
habits, and careers. However, you need to receive
an early and appropriate guidance and training
to use all these devices. Also, you need to be
advised as to which of these devices will be most
helpful in your case, and of which power (for
those devices that vary in power). So, when you
feel you are suffering from low vision, or in
fact any problems of the eyes, you must
immediately walk into or seek an appointment at
Arohi Eye Hospital, the best eye hospital in
Mumbai. The professionals here can help you with
every aspect of diagnosis, determining, and
treatment of any and every eye condition. For
