Abstract
A lens structure formed by materials in different refractive indexes includes a sphere, a first lens and a separation layer which is disposed between the sphere and the first lens. The sphere and the first lens have a different refractive index and the sphere is a round ball. The first lens is formed on the sphere that part of the sphere is exposed out of the first lens, and the first lens includes a first light absorption curve. The separation layer includes a transparent section opposite to the first light absorption curve. When a light beam passes through the second portion of the sphere to form a first light condensing effect and enter the sphere, the light beam will then pass through the transparent section to enter the first lens, forming a second light condensing effect after passing through the first light absorption curve.
