Physical Defects, Maintenance and Handling of Ophthalmic Lenses by Students of Kwame Nkrumah University of Science and Technology
Journal Title: Ophthalmology and Vision Science - Year 2018, Vol 2, Issue 1
Abstract
Introduction: Optical glasses to aid vision are the means for correcting eyesight defects when owned as complete glasses, or when adapted to the ultimate wearer or consumer. A vast majority of people go for corrective lenses to correct their refractive errors and consequently have improved vision. The study was conducted among students at Kwame Nkrumah University of Science and Technology who wear spectacles to determine the physical defects of the spectacles, the level of maintenance and handling of ophthalmic lenses exhibited them. Materials and Methodology: A descriptive cross-sectional study was carried out in Kwame Nkrumah University of Science and Technology (KNUST), Kumasi, Ghana. A simple random sampling strategy was used to select a specified number of students wearing ophthalmic lenses from the six colleges for this study. Thus, 300 students from KNUST were involved in the study. Results: Three hundred (300) students were involved in the study. Of the 300 students, 202 (67.3%) were males and 98 (32.7%) were females. College of Engineering recorded the highest number of males and Colleges of Science and Arts and Social Sciences had majority females. Out of the 98 female students, 18 (18.4%) had a visual effect (asthenopia, diplopia or blurred vision). Similarly, 50 male students out of the 202 had a visual effect. This shows a percentage of 24.7%. Majority (179) students had bent temples, 119 had scratches on their spectacles and students with cracks on their spectacles recorded the least (17). A total of 123 students from all the Colleges used handkerchief to clean their spectacles and lens surfaces. Forty-eight (48) students used tissue, 58 used lens cleaner and 60 students used cotton wool to clean their spectacles. Hundred and eighty-three students keep their spectacles in their cases. A few kept their spectacles anywhere and also in their pockets. Conclusion: The prevalence of the rate of use of dry cloth by students in this study to clean their spectacles shows a deviation from the use of the right spectacle cleaning material (warm soapy water and towel). It can be deduced that a lot of students exhibit poor maintenance habits. Most students do not take good care of their ophthalmic corrective lenses.
