Abstract
Bakalaura darbs ir uzrakstīts angļu valodā uz 44 drukātām lapām, tas satur 30 zīmējumus, 7 grafikus un 3 tabulas. Galvenais darba mērķis bija noskaidrot, kā minerālā stikla lēcas, salīdzinot ar organisko materiālu lēcām, saglabā redzes defektu nemainību. Eksperimentālie pētījumi veikti Itālijā 62 subjektiem vecumā no 11 līdz 19 gadiem, 38 sievietēm un 24 vīriešiem. Ametropiju izmaiņas tika novērotas 9 gadu garumā vienu reizi gadā. Optiskās korekcijas tika veiktas ar minerālā stikla lēcām (indeksi 1,523, 1,6 un 1,7 ) un organiskajām lēcām (1,50, 1,56 un 1,6). Redzes analīze veikta ar ninicist optometrijas 6 punktu testiem. Rezultāti parāda, ka subjektiem, kas 9 gadus nēsāja tikai organiskās lēcas, miopijas pieaugums bija apmēram 2,50 D, kamēr minerālo lēcu nēsātājiem miopijas pieaugums vidēji bija tikai 1,25 D.

This Bachelor work is written in English on 44 printed pages, contains 30 figures, 7 graphics and 3 tables. The main goal of this thesis was to highlight how glass lenses compared to organic material lenses maintain unalterability of the visual defects. Experimental study was made in Italy on 62 subjects aged between 11 and 19 years, 38 female and 24 male. Ametropia changes were monitored for nine years, once a year. Optical correction was made with monofocal glass lenses (index 1,523, 1,6 and 1,7) and organic lenses with index 1.50, 1.56 and 1.6. For visual analysis are using 6 point tests unicist optometry. Results show that for subjects that were for nine years corrected only with organic lenses, averaged myopia increases were about 2.50 dioptres, but for carriers of glasses with mineral lenses myopia increase was in average of 1.25 dioptres. Key words: myopia increase, visual analysis, mineral glass lenses, organic lenses.
