Samenvatting
An attempt is made to get hold on the complex phenomena of glare. It is made plausible that the domain between 10 and 1000 cd /m² is optimal for the perception of fine detail. Ideas are formulated about the mechanism of dazzle and its possible meaning as a warning against ocular damage. Attention is paid to ultraviolet and infrared radiation. No special car is needed for the transmission of sunglasses in this particular domain. Conclusions are drawn in terms of specific technical requirements to be made to sunglasses.
