Sorry I misunderstood, you mean to block blue lights from computer?
Polarised glasses are to reduce glare, more for outdoor sunglasses, not good for computer use.

Blue light lenses
With a technical name of ‘Crizal Prevencia’, this coating helps reduce harmful blue light emitted by the electronic devices we use day to day. Over time, blue light can have an impact on the retina and has been associated with age-related Macular Degeneration^. Continuous use of digital devices can lead to a variety of eye strain symptoms such as tired or dry eyes, blurred vision, headaches as well as back, neck or shoulder pain. The Crizal Prevencia coating, through its blue-light filtering increases visual comfort for the wearer. |
