The mirror lens is 40% brighter than rhodium and is designed to reduce eye strain and stress. This mirror exhibits shadow-free images and is more scratch resistant. In addition to these features, the mirror lens is flush with the plastic head, eliminating the gap that is found in stainless steel heads. This prevents the possibility of corrosion and plaque build-up in that area. The mirror is available in sizes #4 and #5, with a choice of 4 colors (blue, green, gray, and black).
