WHAT IS CATARACT?
Cataract is an eye disease in which the natural lens of the eye becomes cloudy or the transparency of your
lens is either greatly reduced or in some cases completely lost as a result of tissue breakdown and protein
clumping.
Cataracts cloud the eye's natural lens, which is located behind the iris and pupil, and this clouding blurs
vision, making it difficult to see clearly and perform daily tasks. It becomes difficult to do
In a condition in which the lens becomes cloudy, symptoms include blurred vision and cloudiness.
It is also a sign that a scene or more than one scene starts to look double
Difficulty seeing at night can also be experienced. Untreated cataracts can lead to blindness.
As mentioned earlier, a cataract is a cloud over the lens of the eye.
Before a cataract, this lens or this area is clear and transparent which must be called a great gift from God
But as the cataract deepens, it forms a wall between the lens of the eye and the retina, and light rays can
no longer pass through the lens and reach the retina.
The retina is a tissue lining that is very sensitive to light. It has also been reported that it is located at the
back of the eye.
This cloud of cataracts is formed when some of the proteins that make up the lens of the eye begin to
change their structure, and when this process begins, they stand up and obstruct the path of vision.
Another cause of cataracts is a buildup of protein in the eye that prevents the lens from sending clear
images to the retina.
Now let's see what role the retina plays in the eye. The retina has two special functions. Number one, it
converts light coming through the lens into signals. Number two, it sends signals to the optic nerve, which
carries them to the brain.
In cataracts, this lens becomes gradually cloudy when light passes through the lens so cannot be fully
focused on the retina. Just like if the sky is covered with clouds, the light of the sun or the moon does not
reach the earth fully, that is the reason why the patient of cataract sees everything dimly.

Cataracts are often seen in diabetic patients due to secondary medical conditions. A particular
type of cataract occurs in diabetic patients. In addition, high blood pressure can also cause
cataracts.
Obesity, high cholesterol level drug use, and long-term use of steroid corticosteroids are also
causes.
Cataracts can also be caused by vitamin B or vitamin C deficiency and ultraviolet radiation
With aging or injury, the proteins and fibers in the lens begin to break down, causing cataracts.
Hereditary diseases passed down from parents' past surgeries or other health problems are all
among the causes of cataracts.
Cataracts occur when protein forms a layer on the lens of the eye. This natural process continues
with age, leading to a cloudiness that turns into blindness.
Being over 50 years of age, smoking, drinking alcohol, or going out in the sun without sunglasses
are all possible causes.

Treatment
Medical procedure is the best way to dispose of a waterfall
Waterfall medical procedure is the best way to eliminate waterfalls and reestablish your reasonable
vision. During a cataract medical procedure, an ophthalmologist eliminates your obfuscated regular focal
point and replaces it with an intraocular focal point (IOL). An IOL is a counterfeit focal point that for all
time stays in your eye
