Photochromic FlatTop lens: - - - - 1) How Do Bifocal Lenses Work? Bifocal lenses are perfect for people suffering from presbyopia- a condition in which a person experiences blurred or distorted near vision while reading a book. To correct this problem of distant and near vision, bifocal lenses are used. They feature two distinct areas of vision correction, differentiated by a line across the lenses. The top area of the lens is used for seeing distant objects while the bottom part corrects the near-vision. | | - - - - 2) Benefits of Photochromic Lenses # They are highly adjustable to varying lighting conditions in indoor and outdoor environments # Protect your eyes from harmful UVA and UVB rays of the sun # They eliminate the use of separate prescription glasses as they are suitable for most frames and prescriptions # Photochromic lenses are versatile as they can be enhanced using additional treatments like anti-glare coating and scratch-resistance coating # Can be used by both adults and children # Since they are distortion free, they can be worn in rains # Ideal for everyday use 3) Why Choose Photochromic Flat Top Lenses? ----Our Flat Top 28 Bifocal Photochromic lenses are manufactured using the same high quality NK55 material(imported from Japan)as our standard lenses, with ultraviolet filter and scratch resistant coating. Flat Top 28 Bifocals provide you with clear, sharp distance and reading vision. ----FT-28 Photochromic Lenses contain light-sensitive molecules that darken and lighten according to the intensity of ultraviolet light. Recent advances in Photochromic technology ensure that they perform consistently across a wide range of temperatures and climates. ----The greater the intensity of the UV rays, the darker the lens becomes. The moment the UV rays are no longer present, the lens begins to fade back to almost clear. Photochromic Lenses do not change while driving in a car. All Photochromic lenses come with 100% UV protection. III. AR coating: The most important benefits of anti-reflective (AR) coating may be the unseen advantagerelief from fatigue and eyestrain caused by glare. AR does have a big cosmetic advantage, but removing the distracting reflections and ghost images that contribute to eyestrain clearly is a bigger benefit. Being more comfortable in anything we do is a benefit, especially when wearing glasses. IV.

If you have these two confuse, photochromic progressive lens is the best choice for you. - - - - | # Progressive lens Progressive lensare also called No-Line Bifocals. They actually have three fields of vision distance, computer, and reading. You can custom your Rx so you can use them for different distances, but thats usually what people use them for.

They darken significantly within about a minute of exposure to bright light, and take somewhat longer to clear. A range of clear and dark transmittances are available. | - - - - III.

Features: Sunglasses protect your eyes from harmful ultraviolet (UV) rays, reduce eyestrain in bright conditions and protect you from flying debris and other hazards. Finding the right pair is key to your comfort, whether youre driving to work or climbing a mountain. All sunglasses offered at REI block 100% of ultraviolet light. 1) The darkness of the sunglasses lens. 2) The colors of the sunglasses lens. # Lens colors affect how much visible light reaches your eyes, how well you see other colors and how well you see contrasts. # Dark colors (brown/gray/green) are ideal for everyday use and most outdoor activities. Darker shades are intended primarily to cut through the glare and reduce eyestrain in moderate-to-bright conditions. Gray and green lenses wont distort colors, while brown lenses may cause minor distortion. # Light colors (yellow/gold/amber/rose/vermillion): These colors excel in moderate- to low-level light conditions. They are often great for skiing, snowboarding and other snow sports. They provide excellent depth perception, enhance contrasts in tricky, flat-light conditions, improve the visibility of objects and make your surroundings appear brighter. 3) The coating of the sunglasses lens. - - - - Mirrored or flash coating refers to a reflective film applied to the outside surfaces of some sunglass lenses. They reduce glare by reflecting much of the light that hits the lens surface. Mirrored coatings make objects appear darker than they are, so lighter tints are often used to compensate for this. | | - - - - III. Color Choices: If you need more color choices, please contact us.

Photochromic lens: Photochromic lenses lenses that are clear indoors and darken when exposed to sunlight offer a convenient way to protect your eyes outdoors from UV rays and bright light without having to carry around a pair of sunglasses. The molecules in photochromic technology work by reacting to UV light. However, temperature can have an effect on the reaction time of the molecules. - - - - # When the lenses become cold the molecules begin to move slowly. This means that it will take somewhat longer for the lenses to adapt from dark to clear. # When the lenses become warm the molecules speed up and become more reactive. This means that they will fade back faster. It can also mean that if youre outside on a hot sunny day, but sitting in the shade, your lenses will be quicker to detect the diminished UV rays and lighten in color. | | - - - - In general, photochromic lenses are bothfor indoor and outdoor activities lens.In the room or at night, the lenses color are basically transparent, the same as the ordinary lenses, like high light transmission performance, relieve visual fatigue,make you see the world more clear.Lens under the action of ultraviolet light in the sun color, ultraviolet dark color change, deep, shallow light-colored ultraviolet light, isolated from UV damage, anytime, anywhere to protect your eyes. Photochromic lenses, when exposed to sunlight/UV rays, will on average take approx 30 seconds to a minute to darken and will continue to darken for a further 10 minutes to full sunglasses tint/shade, returning to an almost clear state within 2 minutes and fully cleared within 5 minutes although excess temperature will affect this.

Photochromic lens: - - - - # What is photochromic lens? Photochromic lenses are [optical lenses] that darken on exposure to specific types of light of sufficient intensity, most commonly [ultraviolet (UV)] radiation. In the absence of activating light the lenses return to their clear state. They are principally used in [eyeglasses] that are dark in bright sunlight, but clear in low ambient light conditions. They darken significantly within about a minute of exposure to bright light, and take somewhat longer to clear. | | # How do photochromic lens work? In the technology, molecules of silver chloride or another silver halide are embedded in photochromatic lenses. They are transparent to visible light without significant ultraviolet component, which is normal for artificial lighting. These processes are reversible; once the lens is removed from strong sources of UV rays the photochromic compounds return to their transparent state | - - - - # Advantages of photochromic lens Reduced costs buying a single pair of dual purpose photochromic glasses that can provide vision for both indoors when clear and providing sunglasses protection outside is more cost effective than buying two separate pairs. UV protection - Photochromic lenses provide full protection against the harmful UV rays of the sun and direct exposure to sunlight can cause serious eye problems and in some cases blindness. Convenience - You only need to own 1 pair of glasses for both indoors and outdoors in the sun as opposed to needing to switch between 2 pairs of regular glasses to sunglasses. You only need to remember to take one dual purpose pair of glasses with you as no doubt at some point we have all forgotten to take our sunglasses out with us only to be caught out by the glare of the sun or even left them behind never to be seen again. Eye Health Reducing your exposure to the suns harmful UV rays can lower the risk of cataracts or other eye/age related problems III. Our equipment: IV.

What is the RT-28? - - - - RT-28 lenses hastwo different lens powers that aid in seeing objects at various distances once the aging process reduces your ability to do so. These are usually prescribed to adults older than 40 years, although some children and younger adults may also need them for focusing problems, which strain the eyes while reading. | | - - - - - - - - | Whatever the reason one might need to obtain prescription for correction of near-vision, bifocals work similarly. That is, the small lower lens segment (also called "seg") has the refractive power you require to correct near vision while the other part of the lens works for distance vision. In using bifocals, you would look through the upper part of the bifocals to focus on farther objects and look down through the lower segment to read or focus on objects at a distance of 18 inches or less. | - - - - Tips of wearing the bifocal lenses. A simple way of wearing bifocals, is to put them on and focus for distance through the upper segment, then, without moving the head (this is most importantno head movement) to lower the eyes to read a book held 18" away and down at an angle of 30 degrees. One thus uses the lower segment for reading. This exercise must be repeated over and over again so that the brain and the eye adapt to a new system of reading. III. Power range IV. Company shows V.

Features 1) The advantages of the 1.56 # Lenses with a 1.56 index are considered the most cost effective lens on the market. They possess 100% UV protection and are 22% thinner than CR39 lenses. # 1.56 lenses can cut to fit the frames perfectly, and these lenses with knife edge finishing would suit those irregular frame sizes (small or large) and would make any pair of glasses look thinner than ordinary. # 1.56 single vision lenses have higher Abbe value, can offer wearers excellent wearing comfort. 2)What are bifocal glasses. Bifocals are two prescriptions combined into a single lens. Trifocals are three prescriptions combined into one lens. Bifocals were originated by Benjamin Franklin in the 18th century when he cut the halves of two spectacle lenses and fitted them into one frame. Bifocals are needed because the distance glasses do not suffice to focus sufficiently for near. As age increases, (in India 38-40 years is the presbyopic age) reading glasses are required to read at a comfortable distance. Rather than taking out the distance glasses and putting on near glasses - - - - | | | - - - - 3)The advantages of the bifocal lenses. With a bifocal, distance and near are clear but the intermediate distance (between 2 and 6 feet) is blurred. Where intermediate is essential for a patient a trifocal or varifocal is required. Take the instance of a piano player. He can see distance and near, but the music notes he has to read are too far away. Hence, he has to have an intermediate section to see them. A lady who plays cards, can see the cards in her hand but cannot see the cards laid on the table. III. Power range IV. Process of the production V.

In the past few years, the optical industry has made great strides in creating new lens technologies designed to filter bad blue light, thus decreasing eye strain, reducing head and neck pain, sleep deprivation and posture problems from viewing digital devices. Optical manufacturers and opticians are successfully improving the whole digital experience for users with the newest computer and office lenses, along with specialized anti blue ray lenses. - - - - | # UV420-cut lens ----UV+420cut technology filters out not only UVA&UVB, but also high-energy visible light(HEV light) of 400nm-420nm ----Latest reasearch has shown that blocking UV and HEV light is critical for protecting eyes against cataracts and age-related macular degeneration(AMD). ----We are still exposed to 60% of Ultraviolet rays on cloudy days and 20%-30% on rainy days. Oue blue cut lens can provide protection under all weathers. | - - - - III. Coating Choice: Hard Coating: Employed to enhance the corrosion resistance or abrasion resistance of the treated surface.

Features Why need the bofical lenses? The aging process includes changes in vision that makes everyday reading more difficult than usual because of the loss of ones ability to focus naturally. This condition is called presbyopia. It is often relieved by wearing special reading glasses. People who have been wearing prescription eyeglasses because of nearsightedness or farsightedness will need bifocals or eyeglasses with two different lens powers to help them see objects at different distances. - - - - Bifocals have two different lens powers that aid in seeing objects at various distances once the aging process reduces your ability to do so. These are usually prescribed to adults older than40 years, although some children and younger adults may also need them for focusing problems, which strain the eyes while reading. | | - - - - The advantages of the bifocal lenses. Some presbyopes opt for progressive multifocal lenses, which gradually change powers from the top portion to the bottom of the lens, without lines to separate them. However, conventional bifocals offer some advantage over progressive lenses, such as providing wider lenses for computer work and reading compared to progressive lenses.

Features: - - - - | # Semi Finished Lens The starting point for freeform production is a semi-finished lens, also known as a puck due to its resemblance to an ice hockey puck. These are produced in a casting process that is also used to manufacture stock lenses. The semi-finished lenses are produced in a casting process. Here, liquid monomers are first poured into moulds. Various substances are added to the monomers, e.g. initiators and UV absorbers. The initiator triggers a chemical reaction that leads to hardening or "curing" of the lens, while the UV absorber increases the UV absorption of the lenses and prevents yellowing. | - - - - # CR39 1).Low Weight: Lenses of hard resin have a gravity 1.31/cm3, almost half of that of standard crown glass.The low weight of the lenses give comfort for the spectacle wearers. 2).Safety: Lenses of hard resin have excellent impact resistance lenses with a centrethinkness of 2mm or more comply with the cen lens-strength norm and the FDA balldrop test norm. 3).Optical Quality: Lenses of hard resin have a very high light transmission(among the highest for optical plastics). The Abbe number is high(57) CR-39 monomer gives a sharp defined image for plastic lens wearers. 4).Special Lens Treatment: Monomer allow for special treatment such as rimless frames, color tinting for style or sunglass. UV-protection and photochromic. 5).Lens Curve Stailing: The impact resistance of CR-39 monomer gives plastic lenses the strength to sustain stable curve design. # AR Coating: - - - - In the dipping process a lacquer is applied to the lens to make it scratch-resistant. Specially adapted lacquers are used for the various plastic materials with different refractive indices. The hard protective coating is about two microns thick. After ultrasonic cleaning the anti-reflective coatings are applied in a vacuum deposition process. The individual lenses are arranged in special racks known as calottes. A modern coating has up to 9 individual layers the overall package is around 400 nanometers thick. The most important benefits of anti-reflective (AR) coating may be the unseen advantagerelief from fatigue and eyestrain caused by glare. | | - - - - III. Technical Data: IV. Prodcution Process: V.
