• Spectacle Lenses

  • Gone are the days when a pair of glasses involved a frame and two simple pieces of glass ground to the correct prescription. With the help of modern technology, both the manufacturing and the design of the spectacle lenses (single vision, bifocal and progressive lenses) have improved greatly. Lenses have become clearer, lighter and visually much more comfortable to look through than anything that was possible just a few years ago.

  • A lens made up to any amount of long or short-sightedness is precision work. It is also vitally important that the wearer looks through the right part of the lens so that there is as little distortion as possible.

    The “Position of wear” affects the visual performance of the lens. Of course we take exact measurements of how the frame fits your face so that the lenses are in the correct position in front of your eyes, thus maximising the clarity of the lens. But the lenses we use incorporate those values into the actual design of the lenses. This results in a larger field of view, less distortion especially in the periphery and better ’teamwork” between the eyes.

  • Many people benefit from “Hi Index” lenses which are up to 40% thinner and lighter than conventional plastic lenses. By using these special plastics your glasses can be made much more comfortable  by reducing the weight and bulk of the lenses. They are also a lot tougher than ordinary plastic and are therefore ideal for rimless frames.

  • All lenses will reflect light whether they are glass or plastic, high or low prescription, bifocal or single vision. These reflections are at best annoying and at worst they reduce contrast, create glare and impair the visual performance of your glasses - you can't see as well with them. An antireflection coating is a very simple yet extremely effective way of eliminating these problems.

    When lenses are being manufactured they can have a special treatment applied to the front and back surfaces that allows more light to pass through the lens and less to be reflected. This helps eliminate the distracting reflections and is cosmetically much more appealing since the lenses basically disappear.

    A hard protective coating is often combined with an antireflection coating and indeed it is very common to have the coating water repellent and easy to clean too. The science behind these coating is quite astonishing and so are the results.

  • Photochromic lenses have a tint that varies automatically depending on the light levels. These lenses react to natural daylight and as the sun gets brighter a chemical reaction within the lens itself makes the lens get darker. Indoors and at night modern photochromic lenses with an antireflection coating are so transparent they are indistinguishable from clear plastic lenses.

  • Many people spend their day either looking at a computer screen or constantly looking from an electronic gadget (phone/tablet, etc) to distance targets, back to gadget then to distance and so on. This creates eyestrain and visual discomfort that needs a modern solution. 

    We now recommend new types of correction to alleviate these problems ranging in the form of vocational lenses. They are designed to give both clear and crisp intermediate and reading vision in one lens. Another option is a lens that bridges the gap between single vision and progressive designs. The latter have additional help for focussing on close work in the lower part of the lens. By the end of the day your eyes will feel more comfortable, clearer and not nearly as tired.
