Presbyopia is a natural aging phenomenon that occurs as the elasticity of the eye's lens decreases with age, making it difficult to see close distances clearly.
It typically begins around the age of 40 and can occur in anyone.

What is a cataract?
Cataracts are a condition where the lens inside the eye, which functions like a camera lens, becomes cloudy, causing blurred vision.
A normal lens is transparent, accurately transmitting light to the retina. However, when cataracts develop, the lens becomes cloudy, causing vision to appear hazy like looking through fog and making light appear blurred.

Causes of Cataracts
Age
This is the most common cause of cataracts. As we age, the lens gradually hardens and becomes cloudy, leading to cataract formation.
Genetics
If someone in your family has cataracts, your chances of developing cataracts may be higher due to genetics.
Diabetes
People with diabetes have a higher risk of developing cataracts. High blood sugar can affect the proteins in the lens, leading to cataract formation.
Trauma
Damage to the lens following an eye injury or trauma can lead to cataracts.
medication
Steroid medications are a common type of drug that can cause cataracts.
UV exposure
Excessive exposure to ultraviolet rays can damage the cells in the lens, potentially leading to cataracts.
Cataract Treatment
Initial treatment
Follow-up observation and medication
In the early stages of cataracts, if vision loss is minimal and daily life is not significantly impaired, management can involve regular monitoring and slowing the progression with eye drops. However, eye drops alone cannot restore clarity to a clouded lens.
Fundamental treatment
Cataract surgery
The fundamental treatment for cataracts is surgery. The cloudy lens is removed, and an intraocular lens (IOL) is inserted in its place to restore vision.
