Blue light lenses

Blue light lenses, sometimes referred to as computer glasses or blue screen glasses, are blue light blocking glasses that have been treated to filter the amount of blue light wavelengths that reaches the eye. Prolonged exposure to blue light wavelengths, such as through extended use of devices like mobile phones, computers or tablets, has been proven to increase eye strain and the risk of certain eye diseases. Individuals who are exposed to digital screens for multiple hours each day will experience benefits of blue light glasses such as reduced eye fatigue at the end of the work day.
