The UV spectrum is divided into subcategories according to wavelengths as measured by nanometers (nm). A single nanometer is one billionth of a meter (3.3 feet). The HEV range includes wavelengths between 400 nm and 515 nm.
Most quality sunglasses today block virtually all ultra-violet (UV) rays, but many researchers now believe rays in the near-UV range can also cause eye damage over time. The near-UV range is called high-energy visible (HEV), because it includes visible blue/violet light. HEV sunglasses filter out a large portion of this spectrum.
HEV damage is believed to be cumulative, appearing later in life in the form of macular degeneration. Macular degeneration is a condition of the retina that causes a loss of fine detail in vision. This is a chronic condition without cure. Protecting the eyes from near-UV light with HEV sunglasses can help to prevent potential problems later. If damage has already occurred, HEV sunglasses can minimize future exposure, lessening added damage. (Please see Materials Availability Chart)
