Featured is a polycarbonate lens in circular shape. The lens exhibits excellent clarity, refraction index and abbe value. It possesses a&nbsp;lightweight property, which makes it highly ideal for spectacles. <br>
<ul>
    <li>Refraction index (Nd.): 1.591.</li>
    <li>Abbe value: 31Vd.</li>
    <li>Gravity: 1.20g/cm3.</li>
    <li>Ultraviolet protection: 390nm.</li>

Featured is a polycarbonate lens&nbsp;showcases outstanding refraction index and abbe value.&nbsp;Coming in circular shape, the lens possesses a lightweight property. It is&nbsp;highly suitable for&nbsp;manufacturing eyeglasses. <br>

    <li>Abbe value: 31Vd.</li>

This photochromic lens is a clear lens that reacts with UV and produces a tint effect based on the amount of UV present. It can provide&nbsp;a correct amount of protection for varying light conditions. However, when driving, your car windscreen will block a certain amount of UV which is required to make the lens react so they do not work as they do outside of the car.
<ul>
    <li>When wearing photochromic lenses even&nbsp;in&nbsp;a dull day, some reaction will occur producing a very pale tint.</li>
    <li>When wearing on a very bright day when more UV is present, they will turn quite dark.</li>
    <li>When wearing them indoors they will become clear.</li>
</ul>

This is a PC lens that is well-made with special aerospace materials to offer 100% UV protection and avoid the cataract effectively. It&nbsp;has a&nbsp;hard coating processed by the nanometer technique, which ensures this PC lens performs much better in scratch-resistance than hard coated resin lenses. This exquisite lens is an ideal choice for the frameless and semi-frame eyeglasses.
<ul>
    <li>PC HC/HCT lens.</li>
    <li>Developed from the 10 patents of Riccino, we guarantee the lowest inner stress and own the precise optical resolving power.</li>
    <li>25% thinner and 45% lighter than the normal resin lens.</li>
    <li>6% thinner than the 1.60 high index resin lens.</li>
    <li>Highest impact-resistant lens is available and up to 12 times more impact-resistant than the regular plastic lenses, 60 times to the glass lenses.</li>
    <li>Certification: FDA and CE.</li>
</ul>

This is a progressive addition lens that can avoid the discontinuities in the visual field created by bifocal and trifocal lenses and are more cosmetically attractive. The additional lens power required for clear vision at different viewing distances can be adjusted by users by tilting his or her head to sight through the appropriate part of vertical progression. The lens location of the correct addition power for the viewing distance usually only requires small adjustments to the head position since near vision tasks such as reading are usually low in the visual field and distant objects are&nbsp;higher in the visual field.
<ul>
    <li>Since bifocal and related designs are associated with 'old age', proponents have suggested the lack of segments on the lens surface of a progressive lens to appear more 'youthful',&nbsp;and then&nbsp;the single vision lenses are associated with younger wearers which are free of segments or lines on the surface.</li>
    <li>Excellent craftsmanship.</li>
