OUI Inc. is a japanese medical startup founded by ophthalmologists from Keio University School of Medicince. We team up with professionals in the fields of Medicine, Engineering and Business. Our vision to protect health of patients all over the world through our technologies and solutions focused on ophthalmology. We invented Smart Eye Camera (SEC), smartphone attachment medical device which uses light source and camera function of the smartphone to observe the anterior segment of the eye with equal function to Slit-Lamp Microscope. Thre are 43 million people blind worldwide, and the figure is going to increase to 120 million by the year 2050. More than half of these patients are blind because of the reasons which are preventable and curable, since they are residents in the marginalized areas suffering from access to eyecare itself. We aim to make a difference to this situation with our Smart Eye Camera. In collaboration with ophthalmologists, non-ophthalmologist medical doctors, and healthcare workers all around the world, we delivere proper eyecare to these patients and overcome 50% of the world blindness!!
