Single Vision Lenses
The single-vision lens is used to correct many visual defects, for example, short-sightedness, long-sightedness and astigmatism.
Bifocal & Trifocal Lenses
Bifocal lenses are split into two sections by a dividing line. The upper part is for distance vision and the lower part for near vision. They are usually prescribed for people over the age of 40 whose focusing ability has declined due to presbyopia. Trifocal lenses are split into three sections by dividing lines. The upper part is for distance vision, the middle part for intermediate vision and the lower part for near vision.
Progressive or Multifocal Lenses
Progressive lenses are used for correcting presbyopia but unlike bifocal lenses have no visible dividing lines between the different corrections. They are a continuos gradient lens which focuses progressively closer as one looks down through the lens.
Anti-Reflection Coating or Multicoat
Spectacle lenses can be provided with anti-reflection coatings which virtually eliminate distracting reflections off the lens surfaces. Reducing reflected light is particularly helpful for computer users and for night driving. Anti-reflection coatings also improve the cosmetic appearance of your glasses and can make thick lenses look thinner.
Blue Light Multicoat
A coating that is effective in neutralising the blue light emitted by digital devices and protecting eyes from long term damage whilst offering more comfortable and relaxed vision.
Scratch-Resistant Coating or Hard Coating
All of our plastic lenses are supplied with a hard coating as standard to reduce scratching. These coatings help extend the life of your spectacles, although no coating can prevent all scratches.
Photochromatic Lenses or Transition Lenses
Photochromatic, sun sensitive or transition lenses react to light so that indoors or in dull conditions they have a light tint, and in bright light they darken to eliminate glare and protect the eyes against UV rays.
