Residents with visual acuity worse than 20/40 within their better-seeing eyes had been also examined by an ophthalmologist to determine the main cause for reduced eyesight. Cataract was the leading reason behind low vision in both African American and white residents , and was a far more common cause of vision reduction among African American patients than white individuals . Macular degeneration caused low vision in 29 % of white residents and 7 % in African American patients. In four % of white citizens and ten % of African American citizens, glaucoma caused low vision. The higher prevalence of cataract among African American individuals can be attributed to any of several factors. Previous study. Indicates that African American individuals are less likely to go to an ophthalmologist, plus they obtain cataract surgery in lower rates than white colored people, the authors write.The Global Solar UV Index will certainly help raise awareness of the importance of sun protection and ideally will have an impact on reducing the amount of epidermis cancers and cataracts in years to come. With more than one million new situations of skin cancer diagnosed each year in Canada and america, the Global UV Index will not only help people become more aware of the need for sun protection, but help guarantee a consistent approach to educating the general public world-wide also. Other WHO Member States currently using the UVI are Argentina, Australia, Czech Republic, Finland, France, Germany, Greece, Israel, Mexico, Norway, Poland, Portugal, Spain, Switzerland and Sweden.
