Eyeglass lenses are glass or plastic optical items that fit inside eyewear frames to enhance and/or correct the wearer's vision. Due to the increasing demand for eyewear, quartz and beryl lenses were virtually replaced by glass lenses. The convex lens was the first optical lens used in glasses to aid the correction of farsightedness, but other corrective lenses followed, including the concave lens for the correction of near-sightedness, and more complex lenses for the correction of astigmatism. More than 80 percent of all eyeglasses worn today have plastic lenses, but plastic lenses have not always been the lens of choice. The glass lens remained dominant until 1952, when plastic lenses were introduced. The plastic lens rapidly grew in popularity because the lens was lighter and less prone to breakage. Today, the manufacture of plastic eyeglass lenses far exceeds the manufacture of glass lenses, but the process has remained much the same for both types. Plastic as well as glass lenses are produced by successive stages of fine grinding, polishing, and shaping. While the same process is used to produce lenses for telescopes, microscopes, binoculars, cameras, and various projectors, such lenses are usually larger and thicker and require greater precision and power. Ophthalmic glass blanks are manufactured in a limited way in India in organized sector. A huge quantity of blanks is imported. At present the importers of lens blanks select the lens making units to whom they supply blanks in required quantity and the lens manufacturers return the finished lenses to the raw material supplier. Thus the small lens manufacturing units get an assured market for their readymade lenses. Most of the people are using lenses of various types very often. Thus the demand is spiraling high. Applications of optical lenses in a wide range of equipments e.g. microscopes for various needs of students, medical and technical laboratories, Photo enlargers, projectors and over head projectors are well known . In the eyewear industry, it is estimated that 35 per cent of India’s population are in need of vision correction, which may be done by surgery, laser therapy, spectacles or contact lenses. However, only about 25% of people have their vision corrected. Approximately 94 per cent of these wear spectacles, 6% wear contact lenses and 2.5% wear both. The eyewear industry is broadly divided into three categories: eyewear (Sunglasses/ Frames), vision care (Contact lenses) and others (Surgical/Healthcare). In India, eyewear is at the forefront compared to the global markets where vision care has a strong presence. A near stagnant market has been converted into one of the fastest growing industries recording a 20% growth annually. Nevertheless, in global terms the industry in India remains underdeveloped even today. While the Optical retail business is estimated to be approximately 2,300 crore, it is anticipated that the impact of the WTO regime will result in the flow of a larger variety of brands through normal channels in the near future. It is also expected that duties will get lower over the next few years facilitating entry and variety. There is a good scope and market potential in this sector. New entrepreneurs should venture into this field. Few Indian Major Players are as under: Autolite (India) Ltd. Chetan Genthe & Co. Ltd. Forbes Forbes Campbell & Co. Ltd.
