The first thing that you are going to find out about prescription computer glasses is that they are specially designed for viewing electronic devices that emit blue lights. They are mainly used for doing work close to an electronic device and should not be worn for driving or other general purposes. The nice thing about wearing these glasses is that they provide some welcome relief from the stress that you would otherwise feel when working in front of a computer screen or other electronic device. They provide the right amount of shielding from blue lights that are being emitted by electronic devices.
