Drops that are strictly mydriatics, with no cycloplegic drug added, like phenylephrine, dilate the eye for several hours. The side effects of pupil dilation are light sensitivity and blurred vision. Headache and pain in the brow can also occur, according to the Mayo Clinic.
What Are CFCs? CFCs are short for the compound, chlorofluorocarbon, which contain carbon, chlorine, and fluorine. Chlorofluorocarbons are more commonly referred to as CFCs or, when used for refrigeration, CFCs are also known as freon. Developed in the 1930s as a safe alternative to ammonia, usage of CFCs grew rapidly because of its usefulness and convenience throughout most of the 20th century.
What are chlorofluorocarbons (CFCs)? Chlorofluorocarbons (CFCs) are a group of manufactured chemical compounds that contain chlorine, fluorine, and carbon. This group includes CFC-11, CFC-12, CFC-113, CFC-114, CFC-115, and many forms of Freon. They are colorless, odorless, nontoxic, nonflammable, and stable when emitted. When they are emitted and reach the stratosphere, they break apart and release chlorine atoms, which destroy the earthâs ozone layer. CFCs can last for more than 100 years in the stratosphere. Because they destroy the ozone layer, CFCs have been banned from production in the United States since December 31, 1995.
