In this first of a three course series, the history of contact lens development is discussed leading to current lens materials, soft lens design and manufacturing techniques. Parameters such as DK, DK/L, wetting angle, water content, thickness, edge, diameter, monocurve versus multicurve design and sagittal depth will be discussed.
