发明名称 VISION TESTING APPARATUS
摘要 A vision test apparatus includes a viewing assembly connected to a chassis wherein the viewing assembly creates an optical path between an image display and at least one front lens. A near/far assembly includes a secondary lens selectively operable with the front lens to create virtual visual distances. An optional transparent panel intersects the optical path and operates at least partially obscure the image display so that the vision testing apparatus has a means to isolate a portion of the image display. A lifting mechanism is operable to raise or lower the viewing assembly for patients of various heights. The viewing apparatus is also rotatable independently of said chassis to present natural lines of sight to a patient during near and far testing.
