Cataracts, age-related macular degeneration (AMD), glaucoma, retinopathy … the eye can be affected by serious and often degenerative diseases. They can cause further decline in visual acuity and a decreased field of vision. Some can lead to blindness. Anyone can suffer from low vision at any age but the prevalence is higher among the elderly. ‘Low vision’, is the term used for moderate or severe visual impairment that cannot be improved by medication, glasses, contact lenses or surgery.
