Driven by passion for innovation and development, multifocal lens manufacturers are constantly moving boundaries. By use of extensive research and cutting-edge technology the latest free-form multifocal lenses provide clarity in a split second.

Our work situations and needs are not all the same, as the symmetry of our faces are also not all the same, and for this reason you have been supplied with Individualized multifocal lenses, that have been specially customized for your eyes and facial symmetry to meet your specific visual needs. These lenses are the cutting edge of optical lens development worldwide and with the advancements in digital technology and control systems, it is now possible to best satisfy your specific needs. The distance, intermediate, and near zones on these lenses has been customized and blended to meet your individual needs.

Recent research among progressive lens wearers in seven European countries demonstrated that there are five main aspects that contribute most to wearer satisfaction:

1. Ease of switching between the distance and near sections.
2. Ease of finding the reading section.
3. Viewing comfort while reading.
4. Clarity of image (absence of blur).
5. Ease of adaptation.

There is always an Adaptation period for progressive lenses, especially if it is ones first pair. Minor peripheral distortions are unavoidable in progressive lenses. It is impossible to create a seamless (line-free) multifocal lens that has multiple powers for different viewing distances without also creating unwanted distortions somewhere in the lens.

Lens designers and manufacturers have made significant strides in minimizing these distortion areas and "pushing" them to the periphery of modern progressive lenses. But peripheral distortions will be present even when progressive lenses are flawlessly produced using the latest manufacturing equipment and processes — they are an unavoidable optical limitation of all progressive lenses. If you glance to the far right or left, especially when looking down, you might notice your vision is slightly blurred. Peripheral distortions initially might cause you to experience a sensation of "swim" when you make quick head movements.

It is normal for you to experience these problems when you start wearing a new pair of progressive lenses. You can usually eliminate them by making slight head movements to look more directly at objects. A simple rule is to point with your nose where you want to see, and then slowly lift your chin, to find the clear spot on the lens that is suited to your viewing distance. Try to avoid moving closer or further from the object you are looking at, but rather move your chin up or down slowly to find the position on the lens that is suited to that distance.

Most people who notice peripheral vision problems when wearing progressive lenses find that these issues are relatively mild and disappear as they adapt to wearing the lenses over a period of a few days. Be fair to yourself by giving yourself a few days to adapt to your new lenses.

These lenses are available in plastic material. Technological and chemical advancements have produced Plastic materials that are well suited to spectacle lenses. The plastic material most commonly used is known as CR39 ("Columbia Resin 39"). It is a thermal-cured plastic developed in the early 1940s. CR-39 plastic remains a popular material for spectacle lenses because of its light weight (about half the weight of glass), low cost and excellent optical qualities.

A newer lightweight lens material with very good impact resistance called Trivex was introduced for eyewear in 2001. The advantage of this material is its superior optical properties, and great impact resistance properties.

Various newer materials offering a variety of refractive indices are also available.

The refractive index of lenses refers to the light bending properties of the specific material. The more “dense” the material, the higher the refractive index. For example, Air has a refractive index of 1. And pure water has a refractive index of 1.33, and the densest clear material known to man is a diamond, which has a refractive index of 2.4. the higher refractive index also means the specific material reflects light more, as the light cannot enter it easily due to the increased density of the material, that is why diamonds “sparkle” as they do because they reflect the light more.

The refractive index of plastic ranges from 1.498 (CR-39 plastic) to 1.74 (a specific variety of high-index plastic). So, for the same prescription power and lens design, a lens made of CR-39 plastic will be the thickest and a lens made in 1.74 index plastic will be the thinnest. The lens power will determine which refractive index material is best suited for you.

The higher index lenses on tend to reflect light more, and for this reason it is essential to treat the surfaces of these lenses with an Anti-reflective coating.

Tints of virtually any color can be applied to lenses. Lighter tints are often used because these lenses are predominantly used in an office or classroom environment. The tints in these cases are often to just reduce the effect of flicker from fluorescent lights, or the slight flickering of the computer screen. Some users find relief from a slight tint when working in an office, specifically when using a computer most of the day. Color can be added to a lens as a solid tint, where the entire lens has the same color density, or as a gradient tint, where the color density is darkest at the top of the lens and gradually fades to clear or nearly clear at the bottom.

Different colors can be applied to lenses for different purposes. Green, Blue, Green/grey, Grey, Soft Pink and Brown tints used in varying densities depending on user preference, are the most popular for these lenses.

These lenses are also available in different variable tint options, which are light-reactive lenses that adapt to their surroundings, so your eyes don’t have to.

Variable tint lenses:--

1. Give you comfortable vision in all light conditions.
2. Perform consistently in all climates, seasons and circumstances.
3. Darken swiftly to sunglasses outdoors.
4. Fade quickly back to full clarity indoors.
5. Provide 100% protection against UV-A and UV-B rays.
6. Are available in three different colours: bronze brown, silver grey and green.

As a sunglass option, these lenses are also available in polarizing material.

An ultraviolet protective coating can be applied to plastic lenses to block out the harmful Ultraviolet rays. Most high-index plastic lenses have 100 percent UV protection built-in, due to absorptive characteristics of the lens material. Anti-reflective coatings improve vision, reduce eye strain and makes your spectacles look more attractive. These benefits are due to the ability of AR coating to virtually eliminate reflections from the front and back surfaces of your lenses. With reflections gone, more light passes through your lenses to optimize your vision with fewer reflections and ghost images. Apart from the optical benefits, this enhances your appearance by drawing more attention to your eyes and helping you make better "eye contact" with others.

Blue light filtering coatings are also recommended for these lenses, as research has shown that blue light can be a major factor and contributor to fatigue associated with continued computer use. Blue light filter coatings eliminate the harmful portion of blue light while allowing the good portion of blue light to pass through. You can actually see the protection at work as blue light is being reflected off the lens. Due to the reduced amount of blue light entering the eyes, contrasts are improved by reducing screen brightness, flickering and eye fatigue to provide a strain-free visual experience while providing the most complete protection. Apart from the blue filter coating, one should routinely take a short break every hour if your work situation requires extended periods of continuous computer use.

All lightweight plastic lens materials have surfaces that are significantly softer and more prone to scratches and abrasions than glass lenses. Polycarbonate is the softest lens material but is also the most impact resistant. All plastic and high-index plastic lenses require a factory-applied anti-scratch coating for adequate lens durability. Most of today's modern anti-scratch coatings (also called scratch coats or hard coats) can make your lenses nearly as scratch resistant as glass.
