Cataract is a condition where the lens of the eye becomes cloudy, leading to a decrease in vision. It typically develops slowly and can affect one or both eyes. Cataracts are most commonly associated with aging, but they can also develop due to other factors, such as genetics, trauma, diabetes, smoking, and long-term use of certain medications like corticosteroids.

Symptoms of Cataract:
Blurred Vision: Objects may appear blurred, and it may be difficult to see at night.
Faded or Yellowed Colors: Colors may appear less vibrant or have a yellowish tint.
Glare or Halos: Bright lights may cause glare or halos around lights.
Double Vision: Seeing two images from a single object, especially in one eye.
Frequent Changes in Prescription Glasses: An increased need to change glasses or contact lens prescriptions.
Causes:
Aging: The most common cause, as the proteins in the lens begin to break down and form clumps.
Genetic Factors: Family history can increase the likelihood of developing cataracts.
Eye Injuries: Trauma to the eye can cause cataracts to develop.
Health Conditions: Diabetes, high blood pressure, and obesity are associated with an increased risk.
Medications: Prolonged use of corticosteroids or other medications can contribute to cataract formation.
Diagnosis:
An eye doctor (ophthalmologist) will perform a thorough eye exam, including:

Visual Acuity Test: Measures how well you can see.
Slit-Lamp Examination: Allows the doctor to examine the lens and other structures of the eye.
Retinal Exam: Checks the health of the retina and other parts of the eye.
Tonometry: Measures the pressure inside the eye, especially important if glaucoma is suspected.
Treatment:
The most common treatment for cataracts is surgery, which involves removing the cloudy lens and replacing it with an artificial intraocular lens (IOL). Cataract surgery is usually safe and highly effective, improving vision in most cases.

Non-Surgical Treatment: In the early stages, stronger lighting and new glasses or contact lenses may help manage symptoms, but these options cannot stop the progression of the cataract.
Prevention:
While cataracts cannot always be prevented, the risk can be reduced by:

Wearing sunglasses to protect from UV light.
Maintaining a healthy diet rich in antioxidants (e.g., vitamin C and E).
Avoiding smoking and excessive alcohol consumption.
Managing chronic conditions like diabetes effectively.
