There is an extensive range of spectacle lenses and coatings, which help to enhance your vision.
As independent Optometrists, we work with several manufacturers, providing freedom to choose the best lens for you.
SINGLE VISION LENSES
A single vision lens offers the same power through each point of the lens. They are used to focus distance, intermediate, near or any other particular distance, depending on the requirement.
A bifocal lens offers correction at two distances – typically at distance and near. This lens provides greater convenience if you have two different prescriptions for various distances but want the convenience of seeing at both distances in the same pair of spectacles.
An alternative to the bifocal would be a varifocal lens. This is the new generation multifocal lens.
Varifocal lenses are the more popular method of correcting vision at various distances.
The power of the lens changes gradually from the top of the lens (distance prescription) to the bottom of the lens (near prescription). This means that clear vision can be maintained at all distances.
A hard coat is applied to plastic lenses and offers some protection against scratches that can otherwise easily occur on the lens.
ANTI REFLECTION COATINGS
An anti-reflection (AR) coating is a micro-thin film applied to the lens in order to reduce reflections off the lens surface and allow more light to pass through the lens.
An AR coat helps to reduce glare and also improves the appearance of the spectacles by increasing the visibility of your eyes.
Your lenses can be tinted in numerous colours in order to decrease the amount of light entering your eye. Sunglasses are the best example of this. However, it is not necessary to have your lenses as dark as sunglasses. The depth of the tint can be varied depending on your need.
Photochromic lenses react with UV light turning the lens from clear to tinted in a matter of seconds. The latest generation of these lenses has greatly improved recovery times, which means that your lenses will react quickly as you move from indoors to outdoors.
These lenses are ideal for sensitive eyes and glare sufferers. They provide a good alternative to sunglasses, offering greater convenience due to their dual functionality.
All lenses are categorised by their refractive index. By choosing a lens with a higher refractive index, your lenses will be thinner, flatter and therefore lighter than a standard index plastic lens. As well as increasing the comfort of your spectacles, a high index lens improves the appearance of lenses with high prescriptions.
