In contrast to sun protection filters, which reduce the overall visible light in a relatively even manner, cut-off filters only filter out a specific [...] for good vision. Good, glare-free illumination provides a high contrast. In addition, lens coatings, cut-off filters and glasses with side protection can also help. Electronic magnifiers can improve vision [...] specific area of the spectrum, whilst the remaining components of light are able to pass through the cut-off filters virtually unhindered. The areas between transmitted light (transmission) and filtered out
