Protection of Ozone Layer Prevents Cataracts, Says EPA
The Montreal Protocol, the international treaty in effect since 1989 to limit the use of ozone-depleting substances, may save your eyes. According to a report from the U.S. Environmental Protection Agency (EPA), the more robust ozone layer resulting from the Montreal Protocol will prevent more than 22 million cases of cataracts for Americans born between 1985 and 2100; increased exposure to ultraviolet radiation, which occurs with a thin ozone layer, increases the potential for cataracts. The report also notes that the ozone layer, which is broken down by common refrigerants and foam insulation blowing agents that have been largely phased out under the protocol, is expected to recover to pre-1980 levels by 2065.
