A new kind of contact lens, known as the Corneal Refractive Therapy (CRT) lens, only needs to be worn when the user sleeps for them to have perfect eyesight during the following day.
This is according to India Today, which reported that the All India Institute of Medical Sciences could approve the lenses in the Asian country soon.
Assistant professor of ophthalmology at the Dr Rajendra Prasad Centre for Ophthalmic Sciences told the publication: "The CRT lens is similar in appearance to standard contact lenses. We are using it on some people to see the results and they haven"t complained of any infection so far."
There are a few drawbacks however, as those contact lens wearers with long-sightedness will not be able to use the CRT lens.
Researchers at the University of Florida recently carried out work on contact lenses with vitamin E, which would effectively extend the amount of time glaucoma medication bathes an afflicted eye.
