Cataract occurs when the lens of an eye becomes cloudy or opaque, severely diminishing someone’s capacity to see. It’s very common among an ageing population, with the prevalence of cataracts rising from 2.5% for people in their 40’s to 99% for people in their 90’s. Cataracts are the result of a person’s lenses becoming stiffer with age. This condition allows less light to pass through, limiting and scattering the light reaching the retina.
As cataracts progress, the clarity of vision is significantly reduced, with the possibility of the condition reaching a point where neither glasses or Contact Lenses can help.
