Nova Eyewear, the global brand behind new-age vision solutions for nurturing healthy vision for healthy living, has stepped-up its innovation to address the growing concerns with rising Myopia.
Myopia is more commonly referred to as nearsightedness or the inability to see objects clearly at a distance. On an average, this condition sets in from the age 4 to 12 years, which could affect children’s learning and development. With Myopia on the rise, in terms of frequency and its severity, it calls for measures for prevention and control.
The reason for its escalation has been attributed to two factors, genetics and changing lifestyle habits. Children with either one or both parents with myopia are more likely to be myopic and children who spend more time on activities like reading using handheld devices instead of spending time outdoors are more likely to be myopic.
Further, according to studies, myopia affects almost 30% of the world’s population. Myopia is also estimated to affect 50% of the world’s population and high myopia will affect 10% of the world’s population as per projections.
To address such challenges posed to healthy vision and help control the progression of myopia, Nova has introduced an external solution, namely Nova Myosafe, a revolutionary single vision lens designed under the theory of Horizontal Defocus management. The key concept is the correction of the peripheral ‘hyperopic shift’ that reduces the advance of eye elongation and thus, of slowing the myopia progression in young wearers.
Nova Myosafe lenses focus on the peripheral hypermetropic defocus through horizontal meridian. This allows to slow down the elongation of the eye that, without correction, would have continued the work of accommodation to adapt to the peripheral focal point, causing blurring in the vision of objects at an intermediate/far distance.
The optical design features of Nova Myosafe lenses consist of a central vision area, which provides stable refraction at the geometric center, surrounded by a progressive peripheral vision with asymmetrical positive/myopic defocus in the horizontal meridian.
Nova Myosafe lenses consider specific features of myopic eye’s central and peripheral refraction around horizontal and vertical meridians, providing optical balance by creation of an emmetropic refraction profile. These lenses create peripheral defocus in myopic eyes, providing conditions to influence local neuro regulating mechanisms of eye growth.
These lenses increase accommodation. The visual axis of each eye-reaching lens area where optical power is higher when gazing, the image becomes blurred on fovea, providing conditions to stimulate relaxation of accommodation.
These lenses also induce positive spherical aberration in the eye. The progression of light rays going to the eyes on the edge of the pupil, which creates a positive spherical aberration in the eyes. Nova Myosafe lenses contribute to the preservation of high binocular visual acuity.
