Sažetak
Purpose: The purpose of research was to evaluate the relationship about contrast sensitivity functions and glare with patients supplied with gas permeable and soft contact lenses, as well as the behavior of contrast sensitivity and glare in a control group. Methods: There were no restrictions of gender, age or race. In the GP group, n= 82 eyes were tested, ages ranged from 20 to 41 (31.29 ± 5.97). In the soft contact lens group, also n= 98 eyes of subjects were recruited between the age of 20 to 45 (29.79 ± 6.06). The healthy volunteers were in the control group, n= 98 eyes from 20 to 38 years old (27.17 ± 5.65). The KR- 800S Auto Kerato-Refractometer was used, a device provided from Topcon Inc. with which different measurements, such as objective and subjective refraction, examination of contrast sensitivity and also visual acuity under glare condition, as well as pupil size, could be done Results: The study has shown that BCVA decreases in all groups when decreasing contrast (p<0.01). Further, there is a measurable decrease in BCVA under glare conditions in each group (p<0.01). Repeated ANOVA measures revealed statistically significant differences for low contrast visual acuity values between groups and control group (p<0.01). Additionally, it was shown that BCVA in all groups does not differ from the control group. Conclusions: The major outcome of this study is that visual acuity decreases if contrast decreases or if measured with an additional glare source. This means that even in the healthy population, who do not require any optical devices ; low contrast and glare have impact on vision.
