3 inch Bifocal Lens Hand-held Magnifying Glass For Discovery New Thing

~Wholesale Handheld Magnifier~

Magnifiers are all familiar to everyone. Through water, glasses and a newspaper. Fill a cup with a large amount of clear water, so that the glass gives the water a curved surface, like a thick, thin convex lens in the middle. Pick up a newspaper in your left hand and pick up a glass in your right hand. Look carefully through the water in the glass. What will be the difference between these words? Through the glass reading newspapers, the word of the newspaper has become much larger, the same as using a magnifying glass to see things. This phenomenon is caused by the refraction of light. Light refracts after it enters glass and water. The surface of the transparent body is curved, and the angle of the reflected light is different. It seems that the object will have different changes. When the glass is made into a convex lens, it can make the object appear larger than the original.

Magnifier Use Magnifier Use Magnifier is a simple visual optic used to observe the details of a magnifier. It is a condenser lens with a focal length that is much smaller than the eye's apparent distance. The size of an object that is imaged on the retina of the human eye is proportional to the angle (viewing angle) that the object makes to the eye.
