A comparative study of visual function of young myopic adults wearing contact lenses vs. spectacles.

PURPOSE

To evaluate the impact of contact lenses wear vs. spectacles wear on visual function of young adults with mild to moderate myopia.

METHODS

57 students (27 male and 30 female) with a mean age of 23 years old participated in the study. Their mean best corrected visual acuity was 10/10 binocularly, all suffered from mild to moderate myopia (-3.75 sph/SD 1.25 sph) and they were both contact lenses and spectacles wearers. The VF-14 questionnaire was administered to assess the contact lenses wear vs. spectacles wear impact score on general daily living among the young individuals. It was used translated in Greek after following the 'translation-back translation' procedure.

RESULTS

The mean VF-14 score among spectacles and contact lenses wearers was 100 and 86.78 (SD 4.08) respectively. Although there was a significant difference between the two groups (p<0.05), both scores were related to a satisfactory functional vision for daily living. The contact lenses wearers were facing difficulty especially while driving at night, seeing steps, as well as doing fine handwork (i.e. sewing, knitting or carpentry).

CONCLUSIONS

The use of both spectacles and contact lenses provides satisfactory visual functioning for daily activities in young individuals suffering from mild to moderate myopia. However, there is a spectacles' wear superiority in personal satisfaction when compared to contact lenses.
