Smart Eye Camera

Spread the ophthalmologists' view to the world

Blindness continues to remain a major problem worldwide.WHO announced that at least a billion people have a visual impairment that can be prevented or has yet to be addressed. Over half of these blindness incidents were caused by cataracts.

We found that one of the major problems is that there is no diagnostic device in the areas where blindness is increasing.Therefore, we invented a solution that has the potential to overcome this problem. The solution, Smart Eye Camera (SEC), is a smart phone attachment that can record and evaluate ophthalmological images and video to help make a diagnosis online.

SEC makes it possible diagnose diseases in the eyelids, conjunctiva, cornea, anterior chamber, iris, cystal lens and anterior vitreus due to its portable slit-lamp comparable to that of professional grade slit-lamp microscope... all within a smart phone attachment.It is a Japan approved medical device, with some of the toughest regulations worldwide, that was invented through the wisdom of the OUI Inc. founded doctors.
*We have evidence which demonstrates SEC's equivalent functionality when compared to a professional slit-lamp microscope in animal experiment.
