The New Frontier in Colour Blind Technology

Discover life from a more colorful perspective.

If you struggle to differentiate between different colours, then there is a good chance that you suffer from a condition known as colour deficiency. Colour deficiency, or colour blindness, affects around 8% of males and just 1% of females and is characterised by the inability to distinguish between colours, with the vast majority of these patients finding it impossible to tell the difference between shades of red and green. Unsurprisingly, the impact that this has on life can be huge. We use colours in more ways than we realise – to identify logos, read instructions and signs and when driving. Being unable to distinguish between them does not only make life trickier than we would like, but in many cases, it can put your health and safety at risk.

Fortunately, there is a solution that enables patients who are suffering from colour deficiency to enjoy the benefit of colour vision. It is known as EnChromaÆ and we are pleased to be able to offer patients the benefit of having their EnChroma® lenses for glasses supplied by us here at our optometry offices in Rosedale, Auckland.

About Colour Deficiency

Contrary to popular belief, patients with colour deficiency do not only see things around them in black, white and shades of grey. In fact, most patients who are colour deficient can see just as clearly as other people but are unable to fully see light that is red and/or green. However, this doesn’t mean that they only mix up these colours. They will also mix up colours that have some red or green light as part of the whole colour, for example purple and blue because they cannot see the natural red light that forms part of the colour purple.

All light contains colours in a complete spectrum. Our vision is determined by this light entering our eyes and hitting the retina, which is the sensitive layer of cells at the back of our eye. The retina has specific cells, called photoreceptors, that are sensitive to specific parts of the spectrum of light – namely the red, green and blue parts. Patients with colour deficiency have an overlap in the sensitivities of their photoreceptors that make it difficult to distinguish between certain colours. As we know, in most patients, this is the red and green colours. For this reason, sometimes people with this type of colour deficiency are referred to as being ‘red-green’ colour blind.

How does EnChroma® work?

EnChroma lenses are designed specifically to help patients who suffer from red-green colour deficiency. They work by selectively filtering out the red and green wavelengths of light at the precise point where the colour sensitivities overlap before hitting the retina, causing far greater contrast between the colours and enabling the patient to be able to distinguish between them.

EnChroma® lenses, which are made from cutting edge Trivex® lens material for optimal clarity, lightness, strength and 100% UV protection are available in a selection of modern, fashionable frames, making it possible for you to find a pair of EnChroma®glasses to suit your style, whatever that may be. The result, the clearer, more vibrant vision that you deserve provided by glasses that make you feel confident and ready for your bright and beautiful future.
