<blockquote type="cite">The new "white" LED street lighting which is
rapidly being retrofitted in cities throughout the country has two
problems, according to the AMA. The first is discomfort and glare.
Because LED light is so concentrated and has high blue content, it
can cause severe glare, resulting in pupillary constriction in the
eyes. Blue light scatters more in the human eye than the longer
wavelengths of yellow and red, and sufficient levels can <a

seeing clearly for safe driving or walking at night.</blockquote>
