Vision loss and visual impairment are among the most significant challenges affecting quality of life.
Their causes vary between genetic and acquired conditions, with the most common including:

Glaucoma:

Glaucoma is a group of eye diseases that damage the optic nerve, often due to increased pressure inside the eye (intraocular pressure). If left untreated, it can cause gradual and permanent vision loss. 

Main Causes:

1. High intraocular pressure

2. Family history of glaucoma

3. Advanced age

4. Diabetes or high blood pressure

5. Eye injuries or long-term use of steroids

1. Gradual loss of peripheral (side) vision

2. Blurred or tunnel vision
