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 hydrogel is 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...
