In the case of a freeform progressive lens, the back surface geometry includes the progressive design. The freeform process utilises semi-finished spherical lenses which are readily available in a wide range of base curves and indices. These lenses are accurately machined on the back side using state-of-the-art generating and polishing equipment to create the exact prescription surface.• the front surface is a simple spherical surface• the back surface is a complex three-dimensional surface<img src="https://sourcing-media.hktdc.com/product-original/Semi-20Finished-20Lens-20Lens-20Blanks-20for-20RX-20Lab/4c1b7279b3dd4c339db6d92dc7ac4065" style="width: 902px;" class="fr-fic fr-dib" data-productmediaid="4c1b7279b3dd4c339db6d92dc7ac4065">Technology for freeform lenses• Provides the flexibility to offer a wider range of high level products, even for the smaller optical laboratory• Only requires a stock of semi-finished spheres in each material from any quality source• Lab management is simplified with significantly fewer SKUs• Progressive surface is closer to the eye - providing broader fields of view in the corridor and reading area• Accurately reproduces the intended progressive design• Prescription accuracy is not limited by the tooling steps available in the laboratory• Accurate prescription alignment is guaranteed<img src="https://sourcing-media.hktdc.com/product-original/Semi-20Finished-20Lens-20Lens-20Blanks-20for-20RX-20Lab/f06c98d256e54ad99a044e044b65cc9b" style="width: 902px;" class="fr-fic fr-dib" data-productmediaid="f06c98d256e54ad99a044e044b65cc9b">

Optimum-vision runs the length of the lens to allow for each distance to be clear:<img src="https://sourcing-media.hktdc.com/product-original/Conventional-20Progressive-20Lens-20Stock-20Multifocal-20Lens/3aa03c8dfacb41b1825961f0ee60fefe" style="width: 858px;" class="fr-fic fr-dib" data-productmediaid="3aa03c8dfacb41b1825961f0ee60fefe">Top of lens: ideal for distance vision, driving, and walking.Middle of lens: ideal for computer vision, intermediate distances.Bottom of the lens: ideal for reading or completing other close-up activities.<h2 style="text-align: left;">Who Needs Progressive Lenses?</h2>As we age, it becomes more difficult to look at objects that are close to our eyes. This is a very common condition called presbyopia. Most people first notice when they have trouble reading fine print, or when they have headaches after reading, due to eyestrain. Progressives are intended for people who need correction for presbyopia, but do not want a hard line in the middle of their lenses.<img src="https://sourcing-media.hktdc.com/product-original/Conventional-20Progressive-20Lens-20Stock-20Multifocal-20Lens/a106a112f1f04a7f8a5da6f93e6a9aae" style="width: 902px;" class="fr-fic fr-dib" data-productmediaid="a106a112f1f04a7f8a5da6f93e6a9aae"><h2 style="margin-top: 13.5pt; margin-bottom: 9pt; text-align: left;">Benefits of Progressive Lenses</h2>With progressive lenses, you won't need to have more than one pair of glasses with you. You don't need to swap between your reading and regular glasses.Vision with progressives can seem natural. If you switch from viewing something up close to something far away, you won't get a "jump" like you would with bifocals or trifocals.<h2 style="margin-top: 13.5pt; margin-bottom: 9pt; text-align: left;">Drawbacks of Progressive Lenses</h2>It takes 1-2 weeks&nbsp;to adjust to progressives. You need to train yourself to look out of the lower part of the lens when you're reading, to look straight ahead for distance, and to look somewhere between the two spots for middle distance or computer work.During the learning period, you may feel dizzy and nauseas from looking through the wrong section of lens. There may also be some distortion of your peripheral vision.<img src="https://sourcing-media.hktdc.com/product-original/Conventional-20Progressive-20Lens-20Stock-20Multifocal-20Lens/41b364eab02a45fd84263750973aa115" style="width: 767px;" class="fr-fic fr-dib" data-productmediaid="41b364eab02a45fd84263750973aa115"><img src="https://sourcing-media.hktdc.com/product-original/Conventional-20Progressive-20Lens-20Stock-20Multifocal-20Lens/ae6ca31e6b814182992126f759433841" style="width: 804px;" class="fr-fic fr-dib" data-productmediaid="ae6ca31e6b814182992126f759433841">You Need A Pair&nbsp;of Anti-blue Progressive&nbsp;LensesAs blue lights nowadays is everywhere, anti-blue Progressive Lenses are ideal for indoor activities, such as watching TV, playing on the computer, reading books and reading newspapers, and suitable for outdoor walks, driving, traveling and daily wear throughout the year.<img src="https://sourcing-media.hktdc.com/product-original/Conventional-20Progressive-20Lens-20Stock-20Multifocal-20Lens/05606de323aa4792a4d82e03204122be" style="width: 902px;" class="fr-fic fr-dib" data-productmediaid="05606de323aa4792a4d82e03204122be">

The sun emits 3 types of UV rays: UVA, UVB and UVC. UVC is absorbed by the Earth’s atmosphere; UVB is partially blocked; UVA rays are not filtered and can therefore cause the most damage to your eyes1. While a variety of sunglasses are available, not all sunglasses provide UV protection – it is important to choose lenses that offer UVA and UVB protection when purchasing sunglasses. Sunglasses help prevent sun exposure around the eyes which can lead to skin cancer, cataracts and wrinkles. Sunglasses are also proven safest visual protection for driving and provide the best overall wellness and UV protection for your eyes outdoors.<img src="https://sourcing-media.hktdc.com/product-original/Sun-20Lens-20Drive-20Lens-20Fashion-20Eyeglasses-20Lens-20Tinted-20Sun-20Lens/caeb5e787eea4b73b81d9a0393a3bf1d" style="width: 902px;" class="fr-fic fr-dib fr-fil" data-productmediaid="caeb5e787eea4b73b81d9a0393a3bf1d">What types of lenses are available?Shades of Gray Tint<img src="https://sourcing-media.hktdc.com/product-original/Sun-20Lens-20Drive-20Lens-20Fashion-20Eyeglasses-20Lens-20Tinted-20Sun-20Lens/b1b0bb0358de45109c1aef9f07d238c2" style="width: 902px;" class="fr-fic fr-dib fr-fil" data-productmediaid="b1b0bb0358de45109c1aef9f07d238c2">Blue Light Blocking Brown/Amber<img src="https://sourcing-media.hktdc.com/product-original/Sun-20Lens-20Drive-20Lens-20Fashion-20Eyeglasses-20Lens-20Tinted-20Sun-20Lens/7a3574e775094ba58b06650e731c420e" style="width: 902px;" class="fr-fic fr-dib fr-fil" data-productmediaid="7a3574e775094ba58b06650e731c420e"> Get into the Green Scene<img src="https://sourcing-media.hktdc.com/product-original/Sun-20Lens-20Drive-20Lens-20Fashion-20Eyeglasses-20Lens-20Tinted-20Sun-20Lens/f4eebeb7d32a43e6ae84a9b82b08e90f" style="width: 902px;" class="fr-fic fr-dib fr-fil" data-productmediaid="f4eebeb7d32a43e6ae84a9b82b08e90f"> Say Hello to Yellow Lenses<img src="https://sourcing-media.hktdc.com/product-original/Sun-20Lens-20Drive-20Lens-20Fashion-20Eyeglasses-20Lens-20Tinted-20Sun-20Lens/951a32c8d0864e0280b526a5aaa525bf" style="width: 902px;" class="fr-fic fr-dib fr-fil" data-productmediaid="951a32c8d0864e0280b526a5aaa525bf"> Blue Sunglass Lenses<img src="https://sourcing-media.hktdc.com/product-original/Sun-20Lens-20Drive-20Lens-20Fashion-20Eyeglasses-20Lens-20Tinted-20Sun-20Lens/bfb94332c1e7480fbadc737d19b2a7d3" style="width: 902px;" class="fr-fic fr-dib fr-fil" data-productmediaid="bfb94332c1e7480fbadc737d19b2a7d3"> Rockin’ Red Sunglass Lenses<img src="https://sourcing-media.hktdc.com/product-original/Sun-20Lens-20Drive-20Lens-20Fashion-20Eyeglasses-20Lens-20Tinted-20Sun-20Lens/34ddbef7ab724b67a3f241a714fa471b" style="width: 902px;" class="fr-fic fr-dib fr-fil" data-productmediaid="34ddbef7ab724b67a3f241a714fa471b">

UV rays can penetrate clouds, which is why photochromic lenses are capable of darkening on cloudy days. Direct sunlight is not required for them to work. They shield eyes from 100 percent of the harmful ultraviolet rays from the sun. This mechanic is also used inside most windshield glasses in cars. Windshields are designed this way to help drivers see in sunny conditions. This also means that since the UV rays that enter a car are already filtered by the windshield, spin coat photochromic eyeglasses will not themselves darken.<img src="https://sourcing-media.hktdc.com/product-original/Photochromic-20Eyeglasses-20Lens/e3e899f3fe5b42a4945dbe28f0342564" style="width: 902px;" class="fr-fic fr-dib" data-productmediaid="e3e899f3fe5b42a4945dbe28f0342564">Blue Block Spin Coat Photochromic Lenses Help Protect Against Harmful Blue LightSpin Coat Photochromic Lenses is available in blue block and non blue block.

It uses three core technologies to control myopia progression, and provides clear vision and myopic defocus simultaneously at all viewing distances.(1) How do the YOULI myopia control lenses that can help slow or prevent myopia progression? Myopia defocus control technology is the answer.Well from the pictures above you can find -- it can change the way light focuses on the retina between the central and peripheral retinal areas. &nbsp;Peripheral defocus theory suggests that this designs work at controlling myopia because they create that all important peripheral myopic defocus, interrupting the feedback loop for the eye to continue lengthening that is our bane in glasses and single vision lens wear.<img src="https://sourcing-media.hktdc.com/product-original/Myopia-20Control-20Eyeglasses-20Lens-20Defocus-20Lens-20Children-20Lens/860d676774be471590354467408adc42" style="width: 902px;" class="fr-fic fr-dib" data-productmediaid="860d676774be471590354467408adc42"> (2) Central refractive correction technologyAccording to the imaging theory of emmetropia, the core optical zone of the YOULI myopia control lens is around 12mm, and the luminosity is basically not reduced. The retina forms a clear object image to achieve the refractive correction effect.
