Simply put, cataract is the phenomenon that the original transparent lens is cloudy. Clouding of the lens is affecting the view. Cataracts are common in the elderly. Cataracts affect one or both eyes, but they do not spread from one eye to the other. More than half of 80-year-old Americans have cataracts or have had cataract surgery.
The lens locates between the iris and the vitreous. Usually, the lens is transparent. After the light passes through the cornea, it must disassemble to display the image on the retina, just as the camera lens focuses on the light. The negatives are the same.
The lens inside the eye becomes cloudy, and when the eye sees it, the cloud forms inside the eye. Most of the cornea is associated with ageing. The disease is sporadic in the elderly. Aside from the age of 80, more than half of Americans have undergone endoscopy.
Remember, it may be in the eyes or both the eyes — the cornea not transmitted to the other eye.

Symptoms of Cataracts
The symptoms of cataract may include:
The Basic Symptoms
- The symptoms of cataract are mainly vision loss.
- In general, cataracts develop a slow and irreversible loss of vision.
- Compared to other eye diseases, cataracts cause less pain.
Possible Symptoms of Cataracts are as follows:
Factors that can accelerate cataract formation are:
- Blurred vision
- Fading of colours
- Changes in tone
- Crystalline myopia
- Halos around the light
- Dark spots in front of the eyes
- The late symptoms are deep vision
Finally, only the fingers can identify in front of the eyes, or only a light vision remains.
Cataract symptom 1:
Looks vague regardless of distance or near object, this is the most significant difference between cataract and presbyopia. The most apparent sign of cataracts is blurred vision because the lens becomes cloudy, and it is not clear if it is near or far.
Cataract symptom 2:
The sensation of cataracts and subsequent persistent images is related to the penetration of light through lens, which is disturbed by the opaque and diseased fibres of the lens.
Cataract symptom 3:
The degree of the glasses is inconsistent. Recently, it was difficult to see lens changes and the refraction of the light in the eyes have changed. The glasses that were originally equipped with diopters became too low or too high and, of course, could not be seen clearly.
Cataract symptom 4:
Sometimes you may feel that presbyopia suddenly improved. Presbyopia Increase due to the increase in the refractive power of the lens. At first, it thought that the vision would be “second spring.” It is myopia, or presbyopia will be more serious.
Cataract symptom 5:
The eyes are more prone to fatigue. The light is blocked, and the eyes need to adjust more effort to get lighter. Imperceptibly loads the eye muscles and makes the eyes more tired.
Cataract symptom 6:
The field of vision becomes like an old yellow-brown photo. In addition to turbidity, the lens will turn yellow. The world seems to have changed colour, contrast, intensity and sadness.
Cataract symptom 7:
Fear of light. I feel so dazzling when I see street lights, or car lights at night when the light penetrates the diseased lens, part of the light scatters around the bottom. The stimulation of people makes people feel dazzling and afraid of the light.
Causes of Cataract
Cataract is an eye lens.
The Basic reason
- The lens of the eye is usually transparent. It is like a lens in a camera, focusing the light behind the eyes.
- The shape of the lens does not change until about 45 years of age. It allows the lens to focus on an object, whether it is near or far.
- As we age, the lens proteins begin to break down. As a result, it becomes opaque. What your eyes see may appear blurry. This condition is called cataract.
Possible causes of Cataracts are as follows:
Factors that can accelerate cataract formation are:
- Eye trauma
- Eye inflammation
- Radiation exposure
- Family history of cataract
- Surgery for another eye problem
- Excessive exposure to ultraviolet light (sunlight)
- Prolonged use of corticosteroids (oral intake) or some other medicine
In many cases, the cause of cataracts is unknown.
Cataract Cause 1:
Senile cataract is the most common cataract. With increasing age, after four or fifty years, the lens will gradually harden and become cloudy, which will cause progressively visual impairment.
Cataract Cause 2:
Traumatic cataract caused by a car accident, blunt injury, puncture of sharp objects, or penetrating intraocular drugs.
Cataract Cause 3:
Concurrent cataract caused by iritis, glaucoma, epiploon pigmentation, etc.
Cataract Cause 4:
Metabolic cataract caused by diabetes, thyroid disease, etc.
Cataract Cause 5:
Drug-induced cataract caused by long-term use of drugs such as steroids.
Cataract Cause 6:
Congenital cataract due to inheritance, chromosomal mutations, intranatal infections, etc., white or grey dark spots can see in the baby’s pupil, and vision development is weak.
Cataract Cause 7:
Radiation Cataract eye damage can cause by the impact of various radiation rays on the electromagnetic spectrum in the eyes, such as microwaves, infrared, visible light, ultraviolet light, X-rays and R-rays. Neutron or proton beam irradiation also it can cause such damage.
How Cataract Forms?
In the eyes of healthy people, there is a biconvex transparent body called a lens. No matter what causes the lens to be degenerate or turbid, making it opaque and even affecting vision, it is called cataract.
Common senile cataracts generally consider being related to lens nutritional metabolism disorders, ultraviolet radiation, endocrine disorders, genetics and other factors. Local eye trauma and intraocular inflammation may be secondary to cataracts.
Cataracts may complicate certain eye diseases. Diabetic cataracts are due to elevated blood sugar Caused by; long-term use of steroid drugs, long-term exposure to radiation will also develop cataracts. Some people will undergo posterior cataracts after undergoing cataract surgery; genetic or congenital lens development disorders and other reasons will cause congenital cataracts.
If cataracts are not troublesome, surgery is usually not required. Cataracts typically do not harm the eyes so that surgery can perform when convenient. However, some people may have other eye diseases, such as diabetic retinopathy, which cannot treat without cataract surgery.
What causes Cataracts?
Sunlight, smoking or excessive exposure to ultraviolet light using certain medications are causes for the development of cataracts.
Who has Cataracts?
Cataracts occur more frequently in people over 55, but occasionally in young people, including newborns.
When Cataracts occurs in the eyes?
Twenty or thirty years ago, in the absence of ultrasonic crystal emulsification, deep-tissue surgery underwent major trauma and the suture and reconstruction period were long. As a result, he had been familiar with the operation and had undergone surgery in difficult times.
Can Cataracts treated with medicine?
The development of the cornea is one day, not two days or a month or two. It is slowly improving; therefore, when the cornea is in its early stages, the doctor will delay the use of the drug.
What are the signs/symptoms of Cataract?
Cataracts usually develop slowly and painlessly. Some signs of possible cataracts include blurred or blurred vision, decreased color perception or a feeling of covering the eye.
What is the cause of Cataract formation?
The viscosity of Cataract is due to the turbidity of the crystal protein due to mutation. It is not recoverable after turbidity, because modification of the protein is reversible.
How often do traditional Cataract surgery result in eye damage?
Although cataract surgery has been completely standardized and achieved excellent results, cataract surgery does not exempt the general rule that there is no risk without surgery. Therefore, your ophthalmologist cannot formally guarantee the success of the intervention.
How is a Cataract treated?
In the early stages of cataracts, you need to dispense your glasses. Lens removal is a general operation and can be removed or replaced.
When Should I Get Surgery?
Patients generally accept as true with that the cornea properly developed earlier than the surgical treatment is needed. If this is not the case, your eye specialists need to see glaucoma and be aware any visual impairment before you begins asking for the options that your eye medical doctor can recommend.
What your doctor needs?
Your doctor doubts your suspicions about the symptoms based on your age and medical history (diabetes, prescription with corticosteroids) and your symptoms.
