Polarized sunglasses are most popular among people because of their outstanding ability to prevent any ultra violet and blue light to filter in easily. Some people wearing polarized sunglasses suffered from severe headaches and nausea because of the incident of wearing polarized lenses at the time of the ache. One of the reasons that a person might experience headaches while wearing polarized sunglasses is that the polarized screens and coatings on the lenses are only meant for use while outdoors. A person who wear their polarized lenses indoors as well as outdoors, are bound to experience headaches, as suitable amount of light does not penetrate through the lens, which produces a strained effect on the eyes. Another reason is the purchase and use of low quality polarized sunglasses which do not offer efficient protection from the ultra violet and blue light. These lenses do not filter the light completely, which results in the penetration of harmful sunlight through the lenses. The low quality polarized lenses also have uneven application of the polarization coating, which affects the vision of an individual, and poses strain which results in headaches. The defected lens of the sunglasses could also be a possible reason for the resultant headaches of wearing polarized lenses. Some individuals who view screens of different electrical devices which have special coatings, like laptops and tablets etc., might also experience nausea and headaches.
