Automated vision screening apparatus and method
This invention is related to a self-service vision screening kiosk that allows individuals to screen their eyesight without assistance. The device includes subjective and/or objective tests via an interactive video and software program that measures visual acuity and contrast sensitivity. The invention is designed to provide a report with test results. The device and method may also provide a means for making referrals, scheduling appointments, ordering lenses, dispensing lenses and/or forwarding prescriptions to eye care professionals or lens manufacturers.
