Description

Foldable multifunctional rechargeable dimming magnifier

Technical Field

The utility model relates to the technical field of magnifying lenses, in particular to a foldable multifunctional rechargeable dimming magnifying lens.

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 (viewing angle) an 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. Historically, the use of magnifying glasses was said to be proposed by the leading Russian Tess in the United kingdom of the 13 th century.
