The Acunis FL-41 filters are intended to aid those with light sensitivity brought on by migraines, traumatic brain damage, and other eye problems, as well as to shield against bothersome glare. Acute light sensitivity is a frequent complication of migraines and other visual conditions that can make them worse. The Acunis lenses offer a more comfortable viewing experience by reducing the transmission of certain light wavelengths that cause glare, as opposed to standard sunglass lenses that attenuate all light wavelengths equally. The lightweight, stylish anthracite frames are made of aluminum.

CR-39 optical quality lenses are the lens material.
