Abstract

A filter, for protection against the sun, of improved contrast sensitivity has a spectral transmission (T lambda ) which for wavelengths ( lambda ) of the incident radiation in the range lambda < 350 nm </=1% and in the range 350< lambda <400 nm is less than 20%, and which in the range 400< lambda <500 nm reaches a value of 5-30% and thereafter, proceeding from the value for T500, increases linearly with the wavelength to its maximum value. This progression is achieved by coating or colouring the filter material. In this case, it is advantageous to provide a component of the coating or colouring so that the spectral transmission (T lambda ) outside the visible spectral range, i.e. for values lambda >780 nm, quickly reaches a value <1% again. <IMAGE>
