Effect of Contact-Lens Hygiene Education on Safe Contact-Lens Practices among University Students in Nigeria

Abstract

Contact-lens use is an important eye-health concern among university students because improper handling, cleaning, storage, wearing, and replacement of contact lenses may increase the risk of eye irritation, corneal infection, conjunctivitis, corneal injury, and other vision-related complications. University students may use contact lenses for vision correction, cosmetic purposes, or both, but some may obtain lenses from inappropriate sources or use them without adequate professional guidance. Unsafe practices such as sleeping with lenses when not recommended, swimming or bathing while wearing lenses, using tap water or saliva to clean lenses, sharing lenses, exceeding recommended wearing periods, reusing expired solutions, and failing to maintain clean storage cases may increase the risk of ocular complications. Contact-lens hygiene education provides an opportunity to improve students' knowledge of appropriate lens care, safe handling, hygiene, replacement, and healthcare-seeking. Against this background, this study investigates the effect of contact-lens hygiene education on safe contact-lens practices among university students in Nigeria. The study will be anchored on the Health Belief Model, Health Literacy Framework, and Social Cognitive Theory. The Health Belief Model explains how students' perceptions of susceptibility to contact-lens-related eye problems, perceived severity, perceived benefits of appropriate lens hygiene, perceived barriers, and cues to action may influence their practices. The Health Literacy Framework emphasizes students' ability to access, understand, evaluate, and apply information concerning contact-lens care and eye health. Social Cognitive Theory emphasizes observational learning, self-efficacy, peer influence, reinforcement, and environmental factors in developing and maintaining appropriate contact-lens practices. Collectively, these theoretical perspectives provide a suitable framework for explaining how contact-lens hygiene education may influence safe contact-lens practices among university students in Nigeria. The study will adopt a quantitative quasi-experimental or analytical cross-sectional research design. The study population will comprise undergraduate and postgraduate students aged 18 years and above who use contact lenses and are enrolled in selected public and private universities across Nigeria. A multistage sampling technique will be used to select geopolitical zones, states, universities, faculties or departments, levels of study, and eligible contact-lens users. Contact-lens hygiene education will be assessed using indicators such as exposure to educational sessions, frequency and duration of education, information on hand hygiene, lens insertion and removal, cleaning and disinfection, appropriate contact-lens solutions, storage-case hygiene, replacement schedules, wearing duration, sleeping with lenses, water exposure, swimming and bathing precautions, lens sharing, cosmetic lens safety, professional eye examinations, recognition of eye infection symptoms, and appropriate healthcare-seeking. Safe contact-lens practices will be assessed using indicators such as washing and drying hands before handling lenses, appropriate cleaning and disinfection, using recommended contact-lens solutions, maintaining clean storage cases, replacing lenses and solutions according to professional recommendations, avoiding contact with tap water and saliva, avoiding lens sharing, observing recommended wearing schedules, avoiding inappropriate overnight wear, removing lenses when experiencing discomfort or irritation, obtaining lenses from appropriate sources, attending recommended eye examinations, and seeking prompt professional care when signs of eye infection occur. Data will be collected using structured questionnaires, standardized contact-lens knowledge and practice assessment tools, practical observation checklists where appropriate, and relevant university eye-health or optometry records. Descriptive statistics will be used to summarize students' characteristics, contact-lens use patterns, reasons for contact-lens use, sources of information, exposure to hygiene education, and safe contact-lens practices. Inferential statistical techniques, including chi-square tests, t-tests, correlation analysis, and logistic or multiple regression analysis where appropriate, will be used to determine the effect of contact-lens hygiene education on safe contact-lens practices. Where a quasi-experimental design is adopted, safe-practice scores before and after the educational intervention may be compared with those of a comparison group to determine changes associated with the intervention. Diagnostic tests will also be conducted to assess the reliability, validity, and robustness of the findings. The study is expected to find that contact-lens hygiene education has a significant positive effect on safe contact-lens practices among university students in Nigeria. Students exposed to structured and practical contact-lens hygiene education are expected to demonstrate safer contact-lens practices than students without comparable exposure. Education may improve students' understanding of the relationship between poor lens hygiene and eye complications and encourage appropriate handwashing, cleaning and disinfection, safe storage, timely lens replacement, and adherence to recommended wearing schedules. Practical demonstrations may help students avoid unsafe practices such as using tap water or saliva to clean lenses, sharing lenses, sleeping in lenses when inappropriate, and exposing lenses to swimming or bathing water. Education may also improve recognition of symptoms such as persistent redness, pain, discharge, blurred vision, and unusual sensitivity to light, thereby encouraging timely professional eye care. However, cosmetic motivations, peer influence, social-media information, cost of appropriate lens-care products, limited access to optometrists or ophthalmologists, and easy availability of contact lenses from informal sources may reduce the effectiveness of education alone. The study therefore expects accessible, practical, evidence-based, and sustained contact-lens hygiene education, supported by professional eye-care services, to contribute significantly to improved safe contact-lens practices among university students in Nigeria. The study is expected to contribute to the literature on contact-lens hygiene, eye health, ocular infection prevention, university student health, health education, vision health, cosmetic contact-lens safety, health literacy, and public health in Nigeria. The findings will provide useful information to the Federal Ministry of Health and Social Welfare, Federal Ministry of Education, universities, university health centres, optometrists, ophthalmologists, pharmacists, healthcare professionals, public health practitioners, student organizations, eye-health organizations, development partners, and policymakers regarding strategies for improving contact-lens safety. The study will also provide evidence-based recommendations for integrating contact-lens hygiene education into university eye-health programmes, strengthening access to professional eye-care services, improving student awareness of contact-lens-related risks, promoting safe lens-handling and storage practices, strengthening regulation and awareness concerning cosmetic contact lenses, and developing effective health communication strategies for preventing contact-lens-related eye complications among university students across Nigeria.
