Abstract
Maģistra darbs ir uzrakstīts latviešu valodā uz 47 lapaspusēm. Satur 27 attēlus, 5 tabulas, 57 atsauces uz literatūras avotiem un 3 pielikumus. Darba mērķis bija izvērtēt afokālo izeikonisko lēcu radītā palielinājuma ietekmi uz tāluma redzes asumu. 26 pētījuma dalībniekiem (vidējais vecums 21 ± 2 gadi) tika izvērtēts, cik lielu subjektīvo palielinājumu dod afokālās izeikoniskās lēcas (4,45 % un 7,90 % palielinājums). Noteikts, cik lielu subjektīvo redzes asuma uzlabojumu tālumā dod izmantotās lēcas. Ar FrACT10 programmu un modificēto datorizēto anizeikonijas testa palīdzību tika konstatēts, ka 4,45 % un 7,90 % attēla palielinājumu subjektīvi izjūt kā 3,61 % un 6,92 %. Šīs lēcas uzlabo redzes asumu attiecīgi par 0,05 un 0,13 LogMAR vienībām.
The master’s thesis is written in the Latvian language and contains 47 pages. It includes 27 pictures, 5 tables, and 57 references and 3 appendixes. The master's thesis aimed to evaluate the effect of magnification produced by aphakic iseikonic lenses on distance visual acuity. For 26 participants (mean age 21 ± 2 years) assessed how big the subjective magnification was provided by aphakic iseikonic lenses (4.45% and 7.90% magnification). Also was determined the subjective improvement in distance visual acuity of the used lenses. Using the FrACT10 software and the modified computerized aniseikonia test, the 4.45 % and 7.90 % image magnification were subjectively perceived as 3.61% and 6.92%. That improves visual acuity by 0.05 and 0.13 LogMAR units.
