    Progressive lens is a multi-focal lens, which is different from traditional reading glasses and bifocal reading glasses. Progressive lens does not have the fatigue of the eyeball having to constantly adjust the focus when using bifocal reading glasses, nor does it have a clear dividing line between the two focal lengths. Comfortable to wear, beautiful appearance, gradually become the best choice for the elderly.

    As the name suggests the round bifocal is round at the top. They were originally designed to help wearers reach the reading area more easily. However, this reduces the width of near vision available at the top of the segment. Because of this, round bifocals are less popular than the D Seg.
    The reading segment is most commonly available in 28mm and 25mm sizes. The R 28 is 28mm wide at the centre and the R25 is 25mm.

    Photochromic progressive lens is the progressive lens designed with “photochromic molecules” that adapt to varying lighting conditions throughout the day, whether indoors or outdoors. A jump in the amount of light or UV rays activates the lens to turn darker, while little lighting causes the lens to revert back to its clear state.
