OPTICAL LENS
An optical lens for being passed through by an image light includes a first lens, a second lens, and a first shading layer. The first lens has a first optical valid area and a first optical invalid area surrounding the first optical valid area. The second lens has a second optical valid area and a s...

| description | An optical lens for being passed through by an image light includes a first lens, a second lens, and a first shading layer. The first lens has a first optical valid area and a first optical invalid area surrounding the first optical valid area. The second lens has a second optical valid area and a second optical invalid area. The second optical valid area faces the first optical valid area. The second optical invalid area surrounds the second optical valid area. The first shading layer is disposed on a side peripheral surface of the first optical invalid area and a side peripheral surface of the second optical invalid area, providing the function of blocking the non-imaging light, reducing the number of light-shielding parts, reducing the cost of parts, and shortening the assembling time. |
