As the old saying so nearly goes: there are lies, damn lies and advertising. Never was a truer word written. Being a consumer these days is a difficult task. Companies use so much creative license when it comes to describing their products that it's impossible to know where truth ends and the myth begins. To demonstrate the difficulty of judging product value let's look at one particular example: the marketing of Purevision Toric Contact Lenses.
These are part of a new generation of contacts that are revolutionising the eye care industry. Made from a new material called silicon hydrogen they offer previously un thought of levels of comfort and safety. They are highly permeable allowing as much as 98 percent oxygen permeability through to the eye. All that comes at a price. However the manufacturers say its worth it. Anyone who once shunned contacts can now wear them in comfort.
They're not the only brand on the market. In fact if you go looking there are all sorts of products offering varying spins on the silicon hydrogel technology. Acuvue has a range of advanced products that allow people with sensitive eyes to wear contacts without fear. Alternatively, look to Ciba Vision with its Optix Aqua range or indeed Biofinity from Coopervision. All of them make the same bold claims and they all say that only their product has cracked the golden rule.
So how do we tell which one is telling the truth. The only sure fire way is to have a look at the hard cold facts included alongside the marketing speak. To do that we need to know how a product such as Purevision Toric Contact lenses work.
The big advance in silicon hydrogel products is the amount of oxygen they allow through to the eye. Permeability can be up to 98 percent. In other words: virtually natural levels of O2. Why is that important? Eyes need oxygen from the air because they cannot draw it from the blood. Placing a traditional contact over the cornea substantiall reduces the amount of oxygen that can reach the eye. Therefore it quickly begins to suffer if worn for a prolonged period of time.
All products including Purevision Toric contact lenses should include details of their performance on the packaging. The more information provided the more you feel able to trust the information presented. Scrutinise the packaging for details of oxygen permeability and other factors such as length of wear. Next take advice from specialists as well as friends who have used the product. Only then can you make an informed decision.
