How To Manufactured The Eye Lenses
To keep the eyes safe and comfortable, contact lenses are made of many different materials. The major material used in the manufacturing of the contact lens, is a high-grade plastic polymer. Through research into new materials including the new types of polymer the three types of contact lenses were developed over the course of time. They are the hard, soft and gas-permeable contact lens. The gas-permeable lenses are made from Silicone hydrogel. It only takes a couple of hours for the wearer to get used to this type of lens. Since the beginning of the mass popularity of contact lenses, there have been some changes. Manufacturing contact lenses has helped to reduce corneal problems in many contact lens wearers. These new materials are also permit increased efficiency in manufacturing of disposable contact lenses. All of the materials used in the lenses are flexible and gas permeable. Technology transfer contain more than 10% water by weight referred to as hydrophilic. The hydrop...
