    Photochromic lenses are also known as “photosensitive lenses”. According to the principle of reversible reaction of light color alternation, the lens can quickly darken under light and ultraviolet radiation, block strong light and absorb ultraviolet light, and show neutral absorption to visible light. Back to dark, can quickly restore colorless transparent state, ensure the lens transmittance. So the color changing lens is suitable for indoor and outdoor use at the same time, to prevent sunlight, ultraviolet light, glare on the eye damage.

    SETO 1.56 Photochromic Round top bifocal Lens HMC/SHMC

    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.

    When a person loses the ability to naturally change the focus of eyes due to age,you need to look at far and near vision for vision correction respectively and often need to be matched with two pairs of glasses respectively.It is inconvenient.In this case,two different powers made on the different portion of the same lens is called dural lens or bifocal lens.

    Blue cut lenses feature a special coating that reflects harmful blue light and restricts it from passing through the lenses of your eyeglasses. Blue light is emitted from computer and mobile screens and long term exposure to this type of light increases the chances of retinal damage. Wearing eyeglasses having blue cut lenses while working on digital devices is a must as it may help in reducing the risk of developing eye related problems.

    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.

    SETO 1.59 Photochromic Polycarbonate Lens HMC/SHMC

    The chemical name for PC lenses is polycarbonate, a thermoplastic material. PC lenses are also called “space lenses” and “ universe lenses”. PC lenses are tough,not easy to break and have strong eye impact resistance. Also known as safety lenses, they are the lightest material currently used for optical lenses, but they are expensive. Blue cut PC lenses can effectively block harmful blue rays and protect your eyes.

    Index 1.60 lenses are thinner than Index 1.499,1.56 lenses. Compared to Index 1.67 and 1.74, 1.60 lenses have higher abbe value and more tintability.blue cut lens effectively blocks 100% UV and 40% of the blue light, reduces the incidence of retinopathy and provides improved visual performance and eye protection, allowing wearers to enjoy the added benefit of clearer and shaper vision, without altering or distorting color percepyion.An added benefit of photochromic lenses is that they shield your eyes from 100 percent of the sun’s harmful UVA and UVB rays.

    Photochromic lenses change color in the sunlight. Typically, they  are clear indoors and at night and change to grey or brown when  exposed to direct sunlight. There are other specific types of  photochromic lenses that never turn clear.

    Blue cut lens is lens that prevents blue light from irritating the eyes. Special anti-blue light glasses can effectively isolate ultraviolet and radiation and can filter blue light, suitable for watching computer or TV mobile phone use.
