For those who have light sensitivity as a result of migraines, traumatic brain injury, or other eye disorders, the FL-41 Rose Filters are made to be helpful. The rose-colored lenses offer eye relief and prevent glare. For a snug fit, frames have bend-to-fit temples. The Light Rose tint color has a 50% light transmission and is suggested for indoor use. The Dark Rose tint color, which has a light transmission of about 25%, is advised for outdoor use. UVA and UVB rays are completely blocked by both rose filters. Each pair of FL-41 Rose Filters includes a microfiber pocket that may be used to clean the lenses as well as bend-to-fit temples that offer a comfortable, customized fit.
