How Manufacture The Contact Lenses

There are a few different ways to manufacture contact lenses. The most common method is injection molding, where the lens material is melted and injected into a mold. This method is used for mass production of lenses and results in a very consistent product.

Another common manufacturing contact lens expert uses laser cutting, where a lens blank is mounted on a lathe and machined to the desired shape. This method can be used to produce custom or one-off lenses, and allows for more complex shapes to be created.

It begins with the creation of a mold of the cornea, which is then used to create a negative of the lens. From there, a casting process is used to create the positive lens. Once the Silicone hydrogelis created, it goes through a series of finishing processes which includes polishing and hydration.

The manufacturing process of contact lenses is a complex and precise one. Once the lenses have been manufactured, they need to be polished and finished. This usually involves adding a coating to the lens surface to improve durability and reduce reflections. Finally, the technology transfer are inspected for quality control before being packaged and shipped. After that, the lens is ready to be worn!
