The FocusSpecs is a revolutionary technological innovation that enables anybody to fit their own spectacles, and thus correct their own vision. It's a simple as turning a dial. Each lens consists of two optical elements. The strength of each lens changes by shifting the two elements relative to each other.
Adjustable focus glasses are a revolutionary technological innovation. They were invented following years of research and development, during which time the ideas of a Nobel prize winning experimental physicist (Dr. Luis Alvarez) were applied. The FocusSpec® is a low-cost, universal, variable focus spectacle that corrects presbyopia (‘old eyes’) and hyperopia (far-sightedness) with a power range of +0.5 to +4.5 dioptre, and myopia (near-sightedness) at a range between -1.0 and -5.0 dioptre. Each individually adjustable lens consists of two inversely-shaped optical elements, placed exactly behind one another. The strength of each lens changes by shifting the two elements relative to each other.
With such an extensive dioptric range, the FocusSpec® corrects 90% of all refractive errors. In addition, its ease of use means that a lay person can be trained quickly to perform vision screening for others, and then instruct them in the adjustment and fitting of the spectacles. Since the glasses can always be adjusted, more than one person can share a single pair of glasses; and young people can strengthen the power of the lenses as their vision changes over time.
Refractive error (near- and far-sightedness) affects 3.5 billion people globally; and it is increasing rapidly due to an aging population. Luckily, visual impairment has a simple and highly effective treatment: prescription eyeglasses. Nonetheless, up to 2.5 billion people currently live with uncorrected refractive error, 90% of them in the developing world. If the solution is so simple, why does the problem even exist, let alone persist? There are two main reasons. In many countries people lack access to i) eye care professionals, and ii) affordable spectacles. Our innovation surmounts both hurdles, enabling the delivery of corrected vision to anyone, anywhere.
Corrected vision in improves general safety and mobility, and it reduces traffic accidents and road fatalities. It contributes to a safer public space.
Corrected vision drastically improves a person’s quality of life and ability to reach their personal potential. It increases learning in young people, and independence in old age.
Clear vision increases earnings and employment opportunities, and work productivity. Visual impairment is a major development issue, costing low-income countries over $400 billion / annum.
