We've had our eyes on contact lenses
which aim to deliver medicine
for several years. Now, a team of biomedical and chemical engineers from Alabama's Auburn University (AU) claims to have designed the first disposable lenses capable of delivering controlled doses of medication for as long as they're being worn.
If you suffer from hyperopia, more commonly known as farsightedness or longsightedness, you may be interested to know that the world's first contact lens to correct the condition has been developed. The correction, however, is temporary – a custom-made lens is worn overnight to reshape the cornea, and when the patient wakes up and removes the lens they have perfect vision for the day.
If you’re one of the hundreds of thousands of people who spend many hours a day in front of computer or TV monitor you could be suffering from a complaint commonly referred to as eye fatigue. And while you might think your sight is deteriorating and you’re losing your 20/20 vision, it could be that your eyes are just plain tired. Eyewear specialist Gunnar Optiks has a range of glasses with special lenses that are designed to relax your eyes and help avoid tiredness, sore eyes and even headaches associated with gazing at screens all day.
We have seen some interesting and innovative medical uses for contact lenses recently, including dispensing drugs
and even stem cells
to help restore sight. The latest medical breakthrough - contact lenses that change color when glucose levels vary – could signal the end of the sometimes painful and inconvenient process of drawing and monitoring blood throughout the day... a welcome relief for most diabetes
The humble contact lens has long been used to improve people’s vision, but now researchers have restored sight in patients suffering corneal damage using a technique where contact lenses are cultured with stem cells. Fast, cheap and non-invasive, the groundbreaking technique even has the potential for regrowing skin and other organs.
Eye-drops may be a simple way of medicating the eye, but patients don't always get the right dose at the right time. Eyenovations has developed contact lenses that can deliver drugs to the eye in measured doses for a month or longer. The start-up company’s initial focus is developing a lens to help glaucoma patients. However, it believes the technology can be used to help other eye conditions and deliver antibiotics following surgery.
