EPA Report: 22 Million Cataract Cases Will Be Prevented by Stronger Ozone Layer Protection
"The U.S. Environmental Protection Agency marked the beginning of Cataract Awareness Month by announcing a new peer-reviewed report predicting that more than 22 million additional cataract cases will be avoided for Americans born between 1985 and 2100 due to the Montreal Protocol. The environmental treaty, signed by 196 countries, was designed to reduce and eventually eliminate ozone depleting substances. Too much UV radiation not only increases the risk for skin cancer, but also increases the risk for cataracts -- a clouding of the eye’s lens that affects more than 20 million Americans age 40 and older.

“Since the 1970s, we have prevented millions of skin cancer cases and deaths through our work protecting the ozone layer,” said Gina McCarthy, assistant administrator for EPA’s Office of Air and Radiation. “I am excited to kick off Cataract Awareness Month by announcing that the science has now enabled us to estimate our impact on cataracts.”

Due to the success of the Montreal Protocol, the ozone layer is predicted to recover to pre-1980 levels after 2065. In the meantime, under a compromised ozone layer, more ultraviolet (UV) radiation reaches the Earth’s surface. While treatment for cataracts is widely available in the U.S., the costs are high, with direct medical costs estimated to be $6.8 billion per year..."
