Optik Eyecare is proud to be a Nikon Lens Specialist. Nikon cameras and ophthalmic lenses have been renowned for their quality and clarity of vision for over 60 years.
Nikon is a pioneer in lens coatings, including exceptional anti-reflective, scratch-resistant and anti-smudge treatments for increased comfort. They also specialise in progressive lenses using the latest digital production technologies for increased comfort and precision.
Nikon manufactures some of the thinnest, flattest and most precise lenses in the world. Thanks to Nikon, people who wear glasses can find the ideal solution, not only in terms of visual quality, but also aesthetic appeal. In providing you with a Nikon lens we know that you will have great vision through your new glasses.
When it comes time to get new glasses, sometimes all the different terms and options can be a bit overwhelming. Below is an explanation of some of the commonly used terms and lens options.
Most modern optical lenses come with a multicoat on the lens surface. The multicoat reduces the reflected light off the surface of the lens, repels dust and fingerprints, and gives the lens extra strength against scratching. A multicoat is also helpful to reduce visual fatigue when working on computer screens and night time driving.
High index lenses
One of the problems that people with high prescriptions encounter is thick unsightly lenses.
With a high index lens we are able to get a much thinner lighter lens to improve the comfort and appearance of your glasses.
High index lenses are also tougher than basic lens materials, and so your optometrist will recommend them if you choose a rimless or semi rimless frame, to prevent the lenses chipping with use.
After the age of 40, many people begin to notice a deterioration in the clarity of near vision. This is due to an age related change to the focusing lens in the eye, called presbyopia. With the onset of presbyopia the lens required to focus you clearly for distance vision is different to that required for near work. There are a number of lens options to allow presbyopes to have clear vision at all distances. These include bifocals, full progressives and occupational progressive lenses.
Bifocal glasses have the distance prescription at the top of the lens, and a segment of near power towards the bottom of the lens. This allows for clear distance and near vision, but often there is still an area of blurred vision in the intermediate range, which makes bifocals a poor choice for people who do a lot of computer work.
Progressive addition glasses are similar to bifocal, with distance focus at the top of the lens, and near focus towards the bottom. However progressive lenses have a gradual transition between these two powers, enabling a range of different focal distances, depending on which part of the lens you are looking through.
Occupational glasses work in a similar way to progressive glasses, but they are biased more towards intermediate and near work. This type of lens is perfect for someone who spends a lot of time working on the computer and in meetings. Nikon have developed a range of progressives specifically to cater for the visual demands of the modern digitally orientated workplace and home enviroment.
Prescription sunglass lenses come in two main forms, tinted lenses and polarised lenses. Tinted lenses have a UV protectant coating and cut down the brightness of all objects equally. Polarised lenses not only protect against UV light, they also give effective protection from the glare caused by the polarised nature of reflected sunlight. Polarised lenses are particularly helpful to people who spend a lot of time on the water or snow, and to cut down the reflections off windshields of oncoming traffic when driving.
Wearing suitable sunglasses lenses can improve contrast, enhance colour perception, reduce glare and of course protect from harmful UV light. For more information please visit our sunglasses page
Change tint lenses
Change tint lenses, commonly known as the brand name 'transitions' lenses are lenses that are almost clear when indoors, but when outdoors the UV light causes a reaction to a dye that is inserted in the lens in the making process which tints the lenses into sunglasses. Below is a video about transition brand lenses.
