Computer glasses are made specifically for people who spend hours before their computer. Usually computer glasses come with two basic properties- anti reflection and special tinted. Computer screens emit high amounts of light and eyes have to bear this constant light. Eye fatigue and strain is normally associated with this high amount of light and this makes computer glasses really beneficial. Anti reflection coating for the computer glasses makes it reflect the lights from the screen and provide the eyes a better image. This reduces eye strain and fatigue.
