Whatever your requirements, at Morrison's Family Eyecare you will find the solution to suit your vision and lifestyle requirements. We are up-to-date with the latest lens technology including thinner, flatter and lighter materials and anti-reflection coatings to minimise reflections and improve clarity of vision.

Single Vision Lenses
A single vision lens is a lens that serves only one purpose. It is usually used for either reading or for seeing in the distance. The most common material that a single vision lens is made out of is CR39 (plastic), however, they are also available in glass or photochromatic or a plastic that darkens in the sun - called Transitions Lenses.
A bifocal lens is most commonly described as the lens with the line on it. The top section is used for the patient to see in the distance. The bottom section, which is called the seg (segment), is used for reading. There are different types of bifocals, but the most commonly used is called the 28mm D-Seg.
A progressive lens is one that increases in power gradually towards the lower portion of the lens. It is not divided into sections, hence has no visible lines on it. When looking straight ahead, you should be able to see in the distance. When you move your eyes towards the bottom of the lens, you should be able to read. In between, you should be able to look at intermediate distances clearly.
Spectacle Lens Extras
Eliminates nearly all reflections which reduce clarity and look unsightly, it also protects against scratches.
- Reduces reflective glare when working under artificial light
- Reduces 'dazzle' when driving at night
- Prevents annoying ghost images whilst watching a computer or TV screen
- Improves appearance (people will see your eyes not your lenses thus making spectacles even more attractive)
Transitions Lenses automatically adjust to changing light. Indoors, they're as clear as regular lenses. But outdoors, they adjust to the amount of light present, becoming as dark as sunglasses. Transitions Lenses provide convenient protection from several types of glare, including the kind that can seriously diminish vision. In sunlight, mid-light, or indoors, Transitions Lenses are the optimal choice for your everyday lenses.
Exposure to the sun's UV rays is one of the greatest dangers to your vision. Research shows that long-term, unprotected exposure to UVA and UVB radiation can lead to serious eye conditions, such as Cataracts and Macula Degeneration.
Transition Lenses offer you a variety of styles, prescriptions, and materials that best fit your needs.
Transitions Lenses are approved by Optometrists Association Australia for people requiring vision correction and practical UV protection.
Your sight is too precious to trust to just any pair of lenses. With Transitions Lenses you can have quality vision now, while protecting the health of your eyes long-term. Ask us at Morrison's Family Eyecare Centre about Transitions Lenses.'
The high contrast polarising filter helps make vision clearer and brighter by reducing or eliminating glare. Even better, the lens colour automatically adjusts to varying light conditions, further optimising your vision.
Although traditional polarised lenses do a great job of blocking glare, most are too dark to offer optimal vision in the range of light conditions encountered whilst driving or outside.
And whilst traditional photochromic lenses have worked well for people moving between outdoors and indoors, they do not darken significantly behind the windshield of a car, since the windshield blocks the ultraviolet (UV) light that activates the photochromic material. Nor do the traditional photochromic lenses offer polarisation, which is the only way to effectively block blinding glare.
DriveWear lenses are designed to change colour, as they react to varying light conditions both outside and inside the car, to give you the best possible vision in all conditions.

Overcast - Low Light Conditions
At low lighting conditions, Drivewear lenses provide high transmission of light to maximize the total information to all the eye's visual receptors. This results in maximum visual acuity at this low lighting level. The high contrast polarizer removes glare that would otherwise destroy vision in low light conditions. In this stage Drivewear lenses are a high contrast green/yellow colour. Simply, there is no better designed lens for either outdoors or while driving under low light, overcast conditions.
Bright Light - Driving
During bright light conditions behind the windshield of a car, Drivewear lenses provides lower overall transmission to control light intensity for optimum visual acuity. Drivewear lenses promote preferential activation of the eye's red cones (and to a lesser extent, green cones) and result in the best possible vision at these higher light levels. Drivewear's high contrast polarizer is absolutely essential behind the windshield of the car, because it blocks out blinding glare, one of the most dangerous of all driving hazards. Under these conditions, the Drivewear lenses turn a copper colour which many feel is the optimum colour for a driving lens. This unique behind-the-windshield response protects against bright light and glare and provides better sensitivity to the "visual signal" that is vital for safe driving.
Bright Light - Outdoors
In outside bright light conditions, the eyes visual receptors, the rods and cones, can easily get "overpowered" and "oversaturated" with light. Under these bright outside conditions the Drivewear lens is designed for maximum filtration of this excess light. It achieves its maximum dark colour under these conditions. Here again, it is important to provide maximum protection from blinding glare, and only polarized lenses can do this. Drivewear is designed to provide maximum comfort to the wearer in these high outdoor light conditions
