The occurrence of cataract is not limited to a particular age; it occurs at any age, but the chances of getting the disorder increase with increasing age. Cataract is the number one cause of blindness in the world, and it is the leading cause of vision impairment in the U.S. Globally, about 285 million individuals are visually impaired as a result of the cataract. Approximately 20.5 million persons in the United States of America above the age of 40 years have the cataract, and about 6.1 million individuals have gone through an operation to remove their lens. Center for Disease Control and Prevention further estimates the population with cataract to elevate to 31.1 million people by 2020 (Center for Disease Control and Prevention, 2015). According to Mayo Clinic (2016), cataract is the clouding of the clear lens of the eye resulting in decreased vision. A cataract develops gradually, and it can affect either one or both eyes. People with cataract have difficulties in reading, driving and recognizing faces. Some of the causes of cataract include aging, damage of tissues making the lens of the eye, other eye conditions, medical conditions including diabetes, past eye surgery, steroid medications when used for long, and it is also hereditary. Additionally, other factors can increase chances of getting cataract including extreme exposure to sunlight, smoking, high, blood pressure, obesity, and excessive drinking of alcohol. Cataract affects vision in two manners including through clumping of the proteins thereby clouding the lens hence reducing the image sharpness reaching the retina and by changing the clear lens to brownish/yellowish color, making ones vision acquire a brownish tint (National Eye Institute, 2015). However, the good news is that cataract is removable through surgery. Mayo Clinic (2016) indicates that surgery (phacoemulsification) is the safest and effective procedure for cataract treatment.
