LENS MATERIALS
ACTIVE (Poly-Carbonate)
Active lenses are thinner, flatter and lighter than CR-39 and 10 times more impact resistant. Active lenses are more scratch resistant than CR-39 and include UV protection. Active lenses more than comply with the necessary ASA standards.

LENS DESIGNS
SINGLE VISION
Lenses have one focal length or "power" and are used to correct distance or near vision. If the wearer requires spectacles for distance vision and near vision another lens design may be more suitable.

BIFOCAL
Lenses have two focal lengths and are mainly used to correct distance vision and near vision. This is achieved by the eye looking through different segments of the lens. The reading segment is used when the person looks down and inwards to read. Bifocals are available in many designs, however the most common is the Flat Top design. The bifocal has largely been replaced with the Progressive lens design but still has its place. Some wearers find bifocal's the simplest multi-focal lens to be become accustomed to.

PROGRESSIVE
Lenses are designed to correct all distances by a progression of power from the middle of the lens to the lower edge. This lens design offers the wearer a complete eyewear solution for general optical requirements from long distance to middle distance (arm's length) to close up for reading, etc.

ENHANCE (INTERVIEW LENS)
This lens is designed for computer users allowing uninterrupted vision from approx 35cm to 3 meters through a progression of the power from the top to bottom of the lens. Work stations my need to be modified to accommodate wearers of this lens â the screen may need to be raised or lowered depending on the wearers preferred working angles. This lens may also be useful for workshop (machine operators) use. This lens is not suitable for driving or long distance vision.

LENS TREATMENTS
TRANSITION
A variable tint lens that varies according to changing light conditions and has UV protection built-in.

POLARISED
Up to 85% density tint in a neutral grey, green or brown colour. It is particularly good for use outdoors where reflected light is a problem - bright surroundings or water based activities. Includes a built in UV protective filter.

UV PROTECTIVE FILTER
This is a filter that is built into all active (polycarbonate) lenses. The UV filter is colourless and increases the UV protection of the lens to 100%, as required by Australian and New Zealand optical regulations.

ANTI REFLECTIVE COATING
As the name suggests this coating minimises the effects of reflections. It is recommended for all users of VDU appliances and wearers in an office environment. It also offers benefits to professional drivers at night.

ASSEMBLY
All complete prescription safety glasses dispensed by Luxottica Retail Vision Services are certified to the current ASA 1337.6 standards covering prescription safety eyewear for industrial application within the workplace.

The explanations above are a guide only. As each optical prescription is specific to the wearer, individual requirements can only be determined after consultation with our optometrists or optical dispensers.
