The Acunis FL-41 filters are intended to shield eyes from glare and provide relief to people who are sensitive to light because of migraines, traumatic brain injury, or other eye disorders. One frequent side effect of migraines and other eye conditions is acute light sensitivity, which can make them worse. The Acunis lenses offer a more comfortable viewing experience by decreasing the transmission of certain light wavelengths that cause glare, as opposed to standard sunglass lenses that attenuate all light wavelengths equally. The brown stainless steel frames include rubber nose pads that are adjustable for a comfortable fit and top shields for further glare protection!

CR-39 optical quality lenses are the lens material.
