The Contact Lens, Academics, and Self-Perception (CLASP) Study is a small investigational study which seeks to determine the effects refractive error correction has on students from the Franklinton Preparatory Academy (FPA). Previous literature has shown that refractive correction using eyeglasses can be detrimental to one’s self-perception, and opinions about one’s physical appearance. Other studies show evidence that contact lens correction of refractive error can possibly improve one’s self-esteem and their perception of their appearance. In this study, students at FPA were screened according to The Ohio State University College of Optometry’s vision screening guidelines over the course of 3 years. Students who failed the vision screenings were offered a chance to join the CLASP study to receive a comprehensive vision exam with the potential to be fit in soft contact lenses, if the patient wanted. The Self-Perception Profile for Adolescents (SPPA) was performed on all 9th and 10th graders during the 2017-2018 academic year to create a baseline measure and provide initial measures for subjects recruited. This baseline data was also used to perform a Rasch Analysis on the SPPA. The SPPA was later re-administered to subjects during the 2018-2019 academic year to investigate changes in self-perception from refractive error correction. Overall, the vision screening results showed a large unmet need for refractive correction in the student population of FPA, with referral rates nearing 50% every year a screening was performed. The Rasch analysis on the SPPA showed that only the Athletic Competence, Physical Appearance, and Scholastic Competencies can be used to reliably rank subjects. Utilizing mean differences, it was found that subjects fit in contact lenses experienced modest improvements in their Physical Appearance, Athletic Competence, Social Competence, and Global Self-Worth subscales on the SPPA, whereas those in spectacles experienced decreases in all nine subscales. Although these changes were found, they must be interpreted with caution due to the small sample size provided by the subjects, as well as large standard deviations present in all mean measurements. While the SPPA data for this phase of the CLASP study has proven inconclusive, anecdotal evidence exists to suggest that some positive effect on self-perception may exist in the subjects, though the current instrument used may not be sensitive enough to determine this effect, or the sample size needs to be increased in future studies.
