Contact lenses for dry eye worn overnight only while sleeping enable short-sighted dry eye sufferers who normally wear daytime contact lenses to work in climate-controlled office environments and deal with extensive screen-based activities without experiencing major comfort issues. The latter often result in sufferers spending significant amounts of money on eye drops, medication or special devices aimed at treating this condition which now affects millions of people in the UK. Dry eye syndrome has become increasingly prevalent over the past ten years as people spend much more time indoors where air-conditioning systems remove moisture from the air. Additionally, the substantially greater time spent staring at PCs, TVs, smartphones and gaming devices reduces blink rates by up to 80% thus dramatically reducing tear flow to the surface of the eyes.
With the rapid growth in daily disposable contact lens wear, many short-sighted dry eye sufferers find that comfort problems worsen throughout the day but their reluctance to switch to glasses - usually for appearance reasons - often means they will be willing to spend significant sums on dry eye remedies which offer some degree of relief. Over the course of a year, if optician appointments are also taken into account the sufferer could be incurring a total cost equivalent to a two week overseas holiday to simply try and keep the problem to an endurable level. This is why the new ortho-k contact lenses for dry eye are now believed to offer a better and more cost-effective treatment.
Based on the optical science of orthokeratology, overnight ortho-k contact lenses for dry eyes are custom-designed for each individual's eye and work by gently flattening the surface of the eye during sleep. This corrects the focusing distance so that light lands directly on the retina at the back of the eye rather than in front of it which is why distant objects appear blurred to short-sighted people. When the lenses are removed each morning, the wearer has perfect natural vision all day long until the lenses are reinserted at night. Even better is the cost comparison. Not only can those expensive dry eye remedies be forgotten - the ortho-k lenses themselves cost less than a daily cappuchino.
