The progression of myopia may be slowed by wearing dual-focus soft contact lenses, particularly in children, a recent study has claimed.
Dr John Phillips and Dr Nicola Anstice, researchers in the Department of Optometry and Vision Science at the University of Auckland, developed a dual-focus soft contact lens with a central zone that corrects refractive error and presents a clear retinal image.
They found that 70 per cent of children who wore this saw myopia progression slow by 30 per cent or more, while visual acuity and contrast sensitivity were no different in eyes wearing the dual-focus lenses.
The authors concluded that "sustained myopic defocus, even when presented to the retina simultaneously with a clear image, can act to slow myopia progression without compromising visual function".
Contact lenses can "easily treat" irregular astigmatism, which is why lenses have gained so much popularity in recent times, according to UK News Reporter.
