| Abstract: | Colour vision is important in everyday life and colour vision deficiency generally lowers the quality
of life. The objective of the study was to perform tests and measurements to investigate the effects
of gelatine filters on colour vision. Colour vision measurements were carried out using the Ishihara
and Dvorine colour test plates. The visual acuity measurements were obtained using the Snellen
letters. A total number of 12 subjects were tested. The results of the measurements showed that
colour vision improved significantly using the red and orange filters but worsened using the green
and blue filters. Therefore the use of red and orange filters as spectacles is recommended for those
individuals with red-green deficiency. |
