Eye
The eyes are the sensors that detect the reflected light from
an object, pre-process it into a neuron signal and transmit
it to the brain. The brain, after referring to its memory data
bank, then identifies the object.
The eye is an almost
spherical organ, about an inch in diameter, fitted with fatty
tissues inside the eye socket of the skull. The sclera is the
tough protective outer layer of the eye, which we see as the
white of the eyes. The cornea is made of transparent, strong
and smooth material that covers the colored portion of the eye.
Its semi-spherical shape directs light into the pupil.
The iris
The iris, the colored portion of the eye, is made of flexible
muscles, and the aperture in the center is known as the pupil.
The iris muscles contract or expand to different light conditions
and determine the size of the pupil. Heredity decides the color
of the melanin pigment in the iris. Behind the iris is the lens.
The lens focuses the light coming in through the pupil onto
the retina by altering its own shape.
The retina
The retina detects the light, does the initial processing and
transmits it to the brain. The eyelids, along with the lacrimal
gland (tear gland), protect the eyes from injury, dust, germs
and other toxic substances by automatic reflex action We have
two eyes located at a fixed distance apart, so they send two
slightly varying signals according to the angle. The brain processes
these and arrives at a three-dimensional image.
Eye Problems
In an inherited condition like myopia, or near-sightedness,
the distance between the lens and the retina is more than normal,
so the eyes cannot see the distant objects. In the old-age problem
of hyperopia, or farsightedness, the eyeball structure alters,
the distance between the lens and the retina is reduced and
the eyes cannot see close objects. Glasses or contact lenses
can correct both these conditions. A cataract is a condition
where the lens gets clouded and the vision deteriorates. Surgically
replacing the lens with a synthetic lens successfully corrects
the problem. Other eye diseases include conjunctivitis, astigmatism,
glaucoma, sty, tumors, ectropion and entropion.
Simple precautions,
such as wearing goggles in dusty areas like workshops and laboratories,
and wearing sunglasses when there is harsh sunlight, go a long
way in keeping these vital organs functioning smoothly for life.
It's been said that
‘Beauty lies in the eyes of the beholder' but have you
given any thought to those eyes which help you capture this
beauty. By adopting various patterns of life we can give your
eyes a much needed boost. Bringing changes in your lifestyle
and in your eating habits will help you see your eyes in a new
light.

medicine name Triphala is considered to work immensely in favor
of your eyes.
• Consuming
blueberry juice also considered to be very useful for your eyes.
Exercises
• Close both the eyes very tightly by shutting the lids
firmly. Open them suddenly which allows you to feel the stretch.
Once open arch your brows and stretch your face. Repea this
several times a day.
• Look as far
as possible and inhale then look down as far as possible and
exhale. Blink your eyes more than dozen times. Do the same procedure
by turning to your left and right then diagonally up to left,
down to right, up to right and down to left followed by rapid
blinking.
• Rotate your
eyes in all the directions. Slowly and steadily concentrate
one eye at a time. Do this exercise more than dozen times and
try doing this with your eyes shut.
• By using palming
which can be stated as a revised version of the thousand-year-old
yoga tradition known was Hatha Yoga. It relieves strain and
stress from your mind and eyes which needs the required break.
For this you have to warm your hands by rubbing them together
vigorously. Once it’s warm cover the eye without touching
the eyelids. This relaxes the nerves and helps in blood circulation.
• You can also
try sunning which means to use sun's light for your eyes. Move
your head from side to side for the heat to benefit the eyes.
After a while try stretching the eyes to allow more sunlight
to your eyes. Directly looking at the sun is never good. It
is great method to reduce light sensitivity.
• Perform Netra
Basti which is bathing your eyes with clarified butter to reduce
eye strain and to improve eyesight.

What are dark circles
under eyes?

with oil glands unlike the skin on rest of the body. Due to
various reasons the skin under the eyes becomes thin and dry.
Veins below eyes appear prominently when the under eye skin
becomes dry and thin. This lends the area a dark appearance.

Cataract eye surgery
is no exception. But with the development of microsurgical procedures,
cataract eye surgery is quick, generally without discomfort,
and will dramatically restore your vision to the point where
you may require prescription glasses for distance vision or
reading only.
Primarily distinguished
by the clouding of the lens of the eye, a cataract doesn't cause
blindness but instead gradually reduces your vision. It does
this as it grows from a small area of cloudiness that often
goes unnoticed to a much larger area of cloudiness that covers
the entire lens. Initially, you may not even be aware of a change
in your vision. However, over time, cataracts tend to enlarge
to the point where your vision does become affected.
Very basic and straightforward,
cataract eye surgery involves removing the clouded lens and
replacing it with a plastic lens.
There are two fundamental
approaches to this eye surgery.
Phacoemulsification
The first is called Phacoemulsification and is generally the
preferred approach to cataract removal. It involves the use
of sound waves to break up the cataract. Here's how it works:
a small incision is made on the side of the cornea, (the clear,
dome-shaped surface that covers the surface of the eye). The
tip of a microsurgical instrument is inserted into the eye.
This instrument emits high frequency waves which break up the
lens into tiny fragments. The fragments are then removed by
suction, using the same instrument.
Extracapsular
The second fundamental approach is called Extracapsular surgery.
In this approach, a longer incision is made on the side of the
cornea and the core of the cloudy lens is removed in a single
piece. Any remaining fragments of the lens are removed by suction.
Extracapsular surgery requires stitches to close the larger
incision and generally takes six to eight weeks to properly
heal.
In both cases, after
the cornea is removed and replaced with a tiny prescription
lens referred to as an intraocular lens (IOL). Using a alculated
corrective prescription, the IOL clearly focuses light onto
the retina, which dramatically improves vision. The new lens
feels completely natural, you won't notice it at all, just as
you didn't previously notice your cornea.
There are two types
of intraocular lenses used for cataract surgery:
Monofocal
With the monofocal lens implant, the lens acts the same as your
natural lens, except it cannot adjust focus. The lens is shaped
to provide good vision for either farsightedness or nearsightedness,
but is unable to improve both distances. Depending on whichever
range you choose (most often the monofocal lens is used to improve
farsightedness), the other vision distance will require glasses
or regular contact lenses.
Multifocal
With the newer multifocal intraocular lens implant, you’ll
experience normal vision at all distances, which may eliminate
the need for prescription glasses. There are some cautions,
however. Around 4% of those who receive multifocal lenses exerience
some night time glare and halos {spheres of illuminated haze
surrounding sources of light). These side effects tend to decrease
over time and may be minimized with the use of eye drops or
prescription glass for night driving.
As with any surgery,
there can always be complications. Complete healing for cataract
eye surgery may require several weeks, though you should be
able to return to your normal routine fairly quickly. You'll
likely experience some dryness and itching in your eye during
the healing process. Be sure to use your prescribed eye drops
and closely follow your doctor's instructions.
Though cataract eye
surgery may sound a little unnerving, the procedure is generally
quick and painless. More important, it brings with it a 98%
success rate. Don't let the process scare you. Talk with your
ophthalmologist about your particular situation and the best
way to improve your vision.
