Age related macular degeneration (ARMD) results from damage to the macula, a small spot near the centre of the retina. ARMD affects a person’s ability to see straight ahead, known as central vision, and makes reading, driving and recognising close faces and objects more difficult.
Cataracts is clouding of the clear lens, which produces blurring that affects both near and distance vision. Cataracts also increase sensitivity to glare and colours may seem faded or dull.
Glaucoma is a group of diseases that affect the optic nerve. Glaucoma leads to loss of peripheral vision and is often from an increase in pressure within the eye.
Diabetic retinopathy occurs when diabetes causes damage to the tiny blood vessels in the retina at the back of the eye. Symptoms may include blurred or distorted vision and can lead to blindness.
