The straylight measurements in each group were compared in the different conditions.Results: In the near-emmetropic group, a significant effect (p<0.001) of each added negative diopter was found to increase straylight values with 0.006 log-units. In the second group, no significant correlation with type of correcting lens was found on straylight values.Conclusion: Refractive correction with high minus power (contact) lenses result in subtle increase of straylight values. These changes are relatively small and do not lead to visual disability in a clinical setting.Keywords: straylight, contact lenses, eyeglasses, glare, light scatter, refractive error
