Blindness

Blindness is the inability to see or a significant lack of vision. In severe cases, it means being unable to perceive even light. This condition cannot be corrected with eyeglasses, contact lenses, eye drops, or surgery.

Optic Neuritis

Optic Neuritis is because of an inflammation of the optic nerve, which connects the eye to the brain. This swelling causes decreased vision.
It is characterized by inflammation affecting the optic nerve. This disrupts the seamless connection between the eyes and the brain. Eventually, this causes a breakdown of the transmission of visual information from the retina to the brain.

Glaucoma and Diabetes

Diabetes affects the entire body, and the eyes are no exception. The high blood sugars, along with insulin resistance, damage the small blood vessels. In fact, diabetes increases the incidence and rate progression of both, cataract and glaucoma.
