AccuVein uses near-infrared light to illuminate subcutaneous veins and project a live map onto the skin. To get a clear and reliable image, the device must be held at a specific working distance above the site. About seven inches provides the best balance between a wide enough field of view and sufficient light return to differentiate veins from surrounding tissue. At shorter distances, the image can be too small or overly bright, making it harder to distinguish small or deep veins. At a greater distance, the light signal weakens and image resolution drops, reducing visibility of veins. Keeping roughly seven inches away helps maximize vein visualization for easier, safer venipuncture.
