The incidence of myopia is increasing worldwide. At the last VIIIth international conference on myopia held in June 2000 in Boston attention was aroused by the work of Quin et al. on the influence of noctural illumination in rooms where children slept on their subsequent development ofmyopia. Our working hypothesis presented in Hakone in 1996 presumes also a negative effect of light and heat which initiate the development ofmyopia but on eyes with an inborn disposition. We considered asa solutionwearing spectacles withglasswhichallowtopenetrate only visible light and absorb the other wavelengths. These glasses were supplied by Karel Kuběna -TL Technologies. The authors followed up for four years two groups of children with progressive myopia. The progression of myopia during the first two years of the follow up was almost identical in the two groups: in the group with the absorption glasses 0.75 D/year and in the control group 0.77D/year. After two years of wearing the absorption glasses the progression in the group with the absorption glasses was 0.34 D/year and in the control group 0.59 D/year.
