A novel retianl imaging laser eyewear (LEW) scans a narrow laser beam on the retina to enable wearers to see focus-free, full-color images. This LEW is expected to be useful as a visual aid for people with vision impairment. The purpose of this exploratory study is to assess the possibility of the LEW to improve visual ability of ophthalmology patients.
