A lightweight, pocket-sized, hand-held near vision test apparatus (18) that selectively retroilluminates different near vision test objects (40) located on an interchangeable near vision test card (32), or alternatively, selectively diplays near vision test objects (40) on a flat panel display screen. The apparatus allows the examiner to electronically direct the patient's attention to selected near vision test objects (40), while providing a baseline amount of contrast illumination. |
