Progressive Series

Progressive lenses, also known as progressive multifocal lenses, are lenses with multiple focal points that are commonly used to correct vision problems and are particularly suitable for middle-aged and elderly people. The design inspiration for this type of lens comes from the shape of an elephant's nose, which continuously increases the curvature of the front surface of the lens from top to bottom, thereby achieving a corresponding change in refractive power.

Progressive lenses, also known as progressive multifocal lenses, are specially designed eyeglass lenses with multiple focal points that can simultaneously meet various visual needs such as farsightedness, myopia, and presbyopia. The design inspiration for progressive lenses comes from the shape of an elephant's nose, where the curvature of the front surface of the lens increases continuously from top to bottom, resulting in a gradual change in refractive power. This design allows the upper part of the lens to be the distance zone, the middle part to be the medium distance zone, and the bottom to be the near zone, providing clear far, medium, and near vision.

Progressive lenses are lenses with multiple focal points on the same lens. This design allows a pair of glasses to simultaneously meet the visual needs of long-distance, medium distance, and close distance, avoiding the hassle of frequent glasses replacement.
