The image shows a black door with a white paper hanging on it. The paper has the letters "B" and "L" written on it in black ink. Below the letters, there is an eye chart with the words "B", "N", "C", "D", "E", "F", "G", "H", "J", "K", "L", "M", and "E" arranged in a grid-like pattern. The eye chart appears to be a visual representation of an eye test. The door has a red handle on the right side and a small window on the left side. The background is a gray wall.
