What are zero power glasses?
Zero power glasses also known as Plano Spectacles are spectacles with no corrective power. These are widely used as protective glasses to shield the eyes from wind and dust. People with contact lenses often use them for additional protection over contact lenses when they go outdoors. People with eye dryness issues are advised to use zero power glasses, if they do not have spectacle power, to protect from the wind and air-condition blast worsening the dryness.
Two-wheeler riders use zero power glasses as protective eyeglasses, especially at night when they cannot use sunglasses. Stylish people and celebrities often use zero power spectacles as accessories to complete a look. Some professionals use zero power spectacles to create a sophisticated or geeky look for themselves. Hence, zero power glasses have been around for a long time and have diverse functions.
Zero powered glasses with special anti-reflection treatments that filter electro-magnetic rays and blue light from digital devices are also referred to as computer glasses. These glasses are different from prescription glasses since they have no power. Computer glasses with zero power glasses are believed to reduce the digital eye strain. Hence, these are very popular among youngsters who spend long hours on digital devices and IT professionals. However, this is more of a myth created by irresponsible marketing. Just having spectacles with blue filtering properties does not actually do anything to relieve eye-strain or reduce eye-fatigue.

These spectacles have lenses that have a power booster zone. Due to this booster, the eyes feel comparatively less tired after working at near continuously for long hours. If at all there are any glasses that qualify as true computer vision glasses, then it is this category of spectacles.
Most international brands like Essilor, Zeiss, Nikon and others make these special lenses. The same principle is also incorporated in contact lenses by Cooper Vision.

This is instinctive, not intentional. In some people, this leads to recurrent low grade infection. It causes unnecessary irritation. With zero power spectacles, the hands are literally restricted from touching the eyelids. Hence, such unwanted infections can be prevented.
