Purpose This study was carried out to determine the efficacy and characteristics of contact lenses mono-vision as presbyopia optical management in optometry practice in Gaza Strip. Methods 17 subjects were included in this study. Visual functions measured were both eyes distance, intermediate and near vision, stereo-acuity, contrast sensitivity function and reading speed. Comparisons were done between before and after intervention. Contrast sensitivity and reading speed were measured after the intervention only, thus, the results were compared with normal limits. Questionnaire was administered for all participants to evaluate the visual performance and satisfaction level for many daily tasks such as mobility, TV watch, reading newspaper and other tasks. Results contact lenses mono-vision correction significantly improved near vision but intermediate vision was found to be worse with correction. Stereo-acuity showed significant reduction whereas contrast sensitivity remains within normal limits. Reading speed was found to be ideal for fluent reading. All subjects showed adaptation at dispensing visit with significant high level of general satisfaction. Conclusion it has been concluded that contact lens mono-vision correction is an excellent option for presbyopic subjects in Gaza. And it is recommended that this option should be considered widely in presbyopia management by optometrists in Gaza.
