Myopia is one of the leading causes of visual impairment worldwide and is linked to severe eye diseases that can cause permanent blindness. The overall prevalence of myopia has increased substantially in recent years and is estimated to be approaching 50% of the world’s population. Despite the identification of risk factors for myopia progression such as age of onset, genetics, visual environment, and peripheral defocus, the causes of myopia are not fully understood. One theory being investigated is eye’s longitudinal chromatic aberration (LCA). LCA is the dispersion property of optical lenses (including the eye) that shorter wavelengths of light produce shorter focal length than longer wavelengths of light. This means that when white light (visible spectrum) enters the eye, blue and red light are focused in front of and behind the focal point of green light, respectively. Therefore, it was hypothesized that the eye uses this property as a signal to detect sign of defocus which in turns determines whether the eye needs to grow more or stop. This invention is based on this hypothesis. The invention is to propose that reversing LCA i.e. blue and red light being focused behind and in front of green light, respectively, could provide a signal for the eye to slow down (if not stop) the growth. The method that allows for reversing LCA is to use a diffractive lens that is capable of making the eye have opposite sign of the dispersion property.
