Many of us have been in the situation – wanting to close our eyes on a long plane journey or doze off in a comfy armchair after a night out. Then we realise that we are still wearing our contact lenses and we have two choices: take the lenses out or pay the price of leaving them in and waking up with red, sore eyes. Wouldn’t it be great if you could just ignore your lenses and go to sleep, safe in the knowledge that you could wake up and see with clear fresh, healthy eyes? Well, now you can.
Following ten years of trial and development worldwide Bausch & Lomb have introduced lenses that allow healthy and comfortable continuous wear - PureVision™, made from the breakthrough Silicone Hydrogel material, Balafilcon A™. This unique material allows much more oxygen through to your eyes than most of today’s disposable contact lenses. Overnight corneal swelling, an indicator of ocular health, with the PureVision™ lens is comparable to wearing no lens at all.¹ So even when you are asleep your eyes still ‘breathe’ and eye health is maintained.¹
Unlike conventional soft contact lens materials, PureVision™ contact lenses are specifically designed to be worn all the time - even while you're sleeping - for up to 30 days. PureVision™ lenses provide clear, comfortable vision at all times. A major benefit of PureVision™ lenses is that they only have to be taken out and changed every 30 days eliminating the need to clean and handle contact lenses everyday. So if you want a contact lens that gives you the ability to live in, sleep in and forget for up to 30 days*, contact your optometrist today and ask about PureVision™ continuous wear lenses.
