Increasing Cataract Awareness in order to Prevent Blindness – Right to Sight

Cataract is responsible for 51 percent of world blindness, according to the World Health Organization. India is a signatory to the World Health Organization resolution on Vision 2020: The right to sight. Efforts of all stakeholders have resulted in increased number of cataract surgeries performed in India. June has been internationally declared as Cataract Awareness Month to educate the public on risk factors, symptoms and treatment options. Cataract is a clouding of the eye’s lens which blocks or changes the passage of light into the eye. Cataracts usually form in both eyes, but not at the same rate. They can develop slowly or quickly, or progress to a certain point, then not get any worse. 1 Besides aging, other factors may cause cataracts to form. Eye infections, some medicines (such as steroids), injuries or exposure to intense heat or radiation may cause cataracts. Too much exposure to non-visible sunlight (called UV or ultraviolet light) and various diseases, such as diabetes or metabolic disorders, may also contribute to cataracts forming. 3 Age-related– 95 percent of cataracts are age-related, usually after age 40. Congenital– These are present at birth, usually caused by infection or inflammation during pregnancy; possibly inherited. Traumatic– Lens damage from a hard blow, cut, puncture, intense heat or chemical burn may cause cataracts. Secondary– Some medicines, eye disease, eye infection, or diseases such as diabetes cause these cataracts. Radiation– Cataracts can develop after exposure to some types of radiation. 4 As cataracts develop, they often result in a change in the eyeglass prescription. Therefore, at this early stage, new eyeglasses may restore good vision. Regular eye tests are therefore recommended which will help in early detection and subsequent correction of vision.
