Plastic lens and manufacturing method thereof |
| abstract |
(57) [Abstract] [Purpose] To obtain a plastic lens having a predetermined shape with high accuracy and no surface distortion. [Structure] An ultraviolet-tight mold 6, 6'forms an airtight cavity 8 which is the final shape of the lens. These molds 6 and 6 ′ can be divided from the parting surface 14, and these are divided to insert the lens blank 3 into the cavity 8. The lens blank 3 is free from optical distortion, but because of this, the surface shape is distorted. With the lens blank 3 inserted in the cavity 8, a syrup 4 made of a plastic material having a refractive index substantially the same as that of the lens blank 3 is filled, and ultraviolet rays are irradiated from the outside into the cavity 8 through a mold 6 or 6 '. This allows The syrup 4 is polymerized and becomes integral with the lens blank 3. |
