Depending upon the vision defects a person is prescribed suitable lenses for long vision or short vision. Generally after 40 years age a person may have both the defects and accordingly 2 different types of spectacles may be required. One spectacle is required for viewing and another for reading. Many people prefer to go for one spectacle instead of two by opting for Bi focal glasses. In Bi focal glasses, both the types of lenses are combined into one lens. This is very convenient as it gets rid of two glasses. Like any conventional glasses, sunglasses can also be provided with bi focal lenses.
