Introduction to the magnifying glass:

　　A magnifying glass consists of a lens and a handle. The lens of a magnifying glass is a convex lens. The convex lens has the function of magnifying the image of the object, and it is a whole piece of transparent or translucent object. Its refracting surfaces are two spheres, or one sphere and one plane. Magnifier lenses are characterized by being clear and thicker (raised) in the middle. Looking at objects with a magnifying glass can see more details. Magnifier lenses feature a thick center and thin edges. It feels very smooth, not bumpy. Usually surrounded by material.

Precautions for using the magnifying glass:

(1) Do not put it naked in humid air.

(2) Do not wipe with hard objects, so as not to scratch the lens.

(3) Do not use it to watch the sun, so as not to burn the glasses.

(4) Avoid exposure to the sun and place it near fire sources.

The principle of the magnifying glass:

The magnifying glass uses the principle of refraction of light to form an image, which is essentially the refraction of light. In order to see tiny objects or the details of objects clearly, it is necessary to move the object closer to the eye, which can increase the viewing angle and form a larger real image on the retina. But when an object is too close to the eye, it becomes impossible to see clearly.

How to use the magnifying glass correctly:

1. Let the magnifying glass approach the object to be observed, the object to be observed does not move, and the distance between the human eye and the object to be observed remains unchanged, and then the hand-held magnifying glass is moved back and forth between the object and the human eye until the image is large and clear.

2. Keep the magnifying glass as close to the eyes as possible. Keep the magnifying glass still and move the object until the image is large and clear. In order to see tiny objects or the details of objects clearly, it is necessary to move the object closer to the eye, which can increase the viewing angle and form a larger real image on the retina. But when an object is too close to the eye, it becomes impossible to see clearly. In other words, to see clearly, not only should the object have a large enough opening angle to the eye, but also a suitable distance should be taken.
