Description
Technical Field
The utility model relates to a magnifying glass technical field especially relates to a cylinder magnifying glass.
Background
Magnifying glasses are simple visual optics used to view minute details of an object, and are converging lenses with a focal length much smaller than the apparent distance of the eye. The size of an object imaged on the retina of a human eye is proportional to the angle the object is at to the eye. The larger the viewing angle, the larger the image, the more detail of the object can be resolved. Moving closer to the object increases the viewing angle but is limited by the ability of the eye to focus. The magnifying glass is used to make it close to the eyes, and the object is placed in the focal point of the magnifying glass to form an erect virtual image. The magnifying glass has the function of magnifying the visual angle. The amplification effect of the existing magnifier needs to be manually adjusted and cannot be accurately controlled, so that visual fatigue is easily generated when people use the magnifier, and the human health is harmed.
