About the Sharp VA Digital Acuity Technology

You’ve probably seen a computer image that has been enlarged/changed size…it becomes pixilated; and thus, you probably should consider monitor quality & image quality if you’re presenting something as important as optotypes. It seems silly to me to create optotypes out of images that can be distorted. The Sharp VA software is the only acuity software to employ “object-oriented graphics” (vector graphics) for each optotype. Vector graphics use geometrical primitives such as lines, points, and curves. Each optotype is based on geometrical calculations, so one can indefinitely zoom in on our optotypes and they remain crisp. This can be verified with a magnifying loupe. The "sharpness" of the optotypes is limited only by the quality of the monitor (not by image file quality & monitor quality as in other acuity programs). When it comes to presenting optotypes, this seems pretty important to me.
