Effect of TLT Absorption Glasses on the Progress of Myopia in Children

Overview

The incidence of myopia is increasing worldwide. At the last VIIIth internationalconference on myopia held in June 2000 in Boston attention was aroused by thework of Quin et al. on the influence of noctural illumination in rooms wherechildren slept on their subsequent development ofmyopia. Our working hypothesispresented in Hakone in 1996 presumes also a negative effect of light and heatwhich initiate the development ofmyopia but on eyes with an inborn disposition.We considered asa solutionwearing spectacles withglasswhichallowtopenetrateonly visible light and absorb the other wavelengths. These glasses were suppliedby Karel Kuběna -TL Technologies. The authors followed up for four years twogroups of children with progressive myopia. The progression of myopia duringthe first two years of the follow up was almost identical in the two groups: in thegroup 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 groupwith the absorption glasses was 0.34 D/year and in the control group 0.59 D/year.
