Aim: to Know the benefits of low vision aids on visual acuity of low vision patients. Material and Methods: This longitudinal hospital based study, was carried out at Makkah eye complex at low vision clinic. Records of 100 patients with low vision attended in the period from January 2017 to December 2018 to Makkah eye complex were collect. Refraction was done objectively by retinoscope (RISTER), and subjective verification was performed using trial lenses and frame for distance and near, monocular and binocular. Visual acuity was tested for distance by Log mar chart and near by Sudan test. Suitable low vision aid was prescribed for each patient. The measures of each patient were recorded in first visit and at follow up appointment after 6 months. Results: Two hundred eyes of patients with low vision were included in this study. Females were more frequent than males (67% and 33%, respectively). 100% improve vision at baseline, with range <0.3 64% (0.4 – 0.8) 25% >0.8 11% (P value 0.00). Distance visual acuity with low vision aid at baseline was better that after 6 months. The majority of low vision patients were patients were aged 21 to 40 year (38%). The causes similar to that found in most developing countries. Optic atrophy 15%, Glaucoma 11%, retinitispigmentosa 11%, nystagmus 10%. The power of distance low vision aids <3.0 57%, (3-4) 25%, >4.5 18%. Binocular telescope was frequently used as distant correction 38%. Conclution: This study found that there were benefit of low vision aids. So awareness of low vision clinics is necessary.
